Cisco MGC Node Operations

---

This chapter contains recommended operating procedures for the Cisco Media Gateway Controller (MGC) node. In these procedures, the assumption is that all components have been correctly installed, configured, and provisioned in accordance with the instructions provided in the relevant documentation. All components are assumed to have been successfully started, as described in "Cisco MGC Node Component Startup and Shutdown Procedures."

---

Note Operation of the Cisco MGC node should be performed by someone who has been trained in the complexities of the system, who has some experience administering the system, and who understands UNIX at the system administrator level.

---

This chapter contains the following sections:

•Daily Tasks

•Periodic Maintenance Procedures

•Regular Operations

Daily Tasks

The following section detail the procedures you should perform on a daily basis on the Cisco MGC. These procedures use Man-Machine Language (MML) and UNIX commands. These procedures can also be performed using the optional Cisco MGC Node Manager (CMNM) application. For more information on using the CMNM to operate the Cisco MGC, refer to the Cisco MGC Node Manager User's Guide.

The tasks you should perform on a daily basis are found in the following sections:

•Starting an MML Session

•Verifying the Platform State of the Cisco MGC Hosts

•Verifying That Processes Are Running

•Monitoring the Alarms Status

•Verifying the Status of all Destinations

•Verifying State of all SS7 Routes

•Verifying CIC States

•Verifying Available Disk Space

•Verifying Available Virtual Memory

•Verifying Available RAM

•Verifying CPU Utilization Level

•Verifying the Number of Active Processes

•Verifying the Number of Users

•Verifying Available Memory on the Cisco SLTs

Starting an MML Session

When a procedure requires that you start an MML session, you must perform the following steps:

---

Note We recommend that you run your MML sessions from the active Cisco MGC, unless the procedure indicates otherwise.

---

---

Step 1 Log in to the active Cisco MGC.

Step 2 Enter the following command at the UNIX prompt:

mml

If you receive an error message indicating that sessions are already in use, enter the following command:

mml -s session number

Use any session number from 2 through 12 and repeat until you find a vacant session. Once you have successfully started an MML session, the prompt changes to:

machine_name mml>

---

Verifying the Platform State of the Cisco MGC Hosts

You can determine which of your Cisco MGC hosts is the active Cisco MGC and which is the standby Cisco MGC. If your system uses a Cisco MGC in a simplex configuration, the single Cisco MGC host is always active. To do this, complete the following steps:

---

Step 1 Log into one of the Cisco MGCs, start an MML session, and enter the following command to determine its platform state:

rtrv-ne

The system should return a message, similar to the following, if it is currently the active Cisco MGC:

   Media Gateway Controller 2000-03-29 14:15:22

M  RTRV

   "Type:MGC"

   "Hardware platform:sun4u sparc SUNW,Ultra-5_10"

   "Vendor:"Cisco Systems, Inc.""

   "Location:Media Gateway Controller"

   "Version:"7.4(12)""

   "Platform State:ACTIVE"

The valid values for the Platform State field are ACTIVE, STANDBY, or OOS.

Step 2 Log into the other Cisco MGC, start an MML session, and enter the following command to determine its platform state:

rtrv-ne

The system should return a message that indicates that it is in either the active or standby platform state.

If the Cisco MGC hosts have changed their platform state, determine why the switchover occurred by searching the contents of the active system log file, as described in the "Viewing System Logs" section.

If the platform state of either Cisco MGC host is OOS, check the alarms as described in the "Monitoring the Alarms Status" section, and take the actions necessary to correct the condition that caused the associated alarm(s). The alarms that require you to take corrective action and their associated actions can be found in the "Alarm Troubleshooting Procedures" section. A complete listing of alarms can be found in the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide.

If the platform state of both Cisco MGC hosts is active, proceed to Step 4.

Step 3 Verify that the active configuration has not changed by entering the following UNIX commands:

cd /opt/CiscoMGC/etc

ls -l

The system returns a response similar to the following:

total 35350

-rw-r--r--   1 mgcusr mgcgrp     38240 May  8 10:46 02.trigger

-rw-rw-r--   1 mgcusr   mgcgrp     20488 Oct 10  2000 64eisup.bat

lrwxrwxrwx   1 mgcusr   mgcgrp        43 Aug  1 18:55 active_link -> 
/opt/CiscoMGC/etc/CONFIG_LIB/CFG_pol-addipl

-rw-rw-rw-   1 mgcusr   mgcgrp     30907 Jul 24 15:29 alarmCats.dat

-rw-rw-rw-   1 mgcusr   mgcgrp      2064 Jun  4 10:57 alarmTable.dat

-rw-rw-rw-   1 mgcusr   mgcgrp         0 Jun  4 10:57 auxSigPath.dat

Identify the active_link file. The listing indicates which configuration is currently active. The active configuration in the example is CFG_pol-addipl.

If the configuration has changed, you may want to compare the active configuration to the previous configuration.

Step 4 Contact the Cisco Technical Assistance Center (TAC) for assistance. Refer to the "Obtaining Technical Assistance" section for more information on contacting the Cisco TAC.

---

Verifying That Processes Are Running

To verify that the processes on your Cisco MGC are running, perform the following steps:

---

Step 1 Log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-softw:all

The system returns a response similar to the following:

Media Gateway Controller - MGC-04 2000-04-05 08:06:03

M  RTRV

   "CFM-01:RUNNING ACTIVE"

   "ALM-01:RUNNING ACTIVE"

   "MM-01:RUNNING ACTIVE"

   "AMDMPR-01:RUNNING ACTIVE"

   "CDRDMPR-01:RUNNING ACTIVE"

   "DSKM-01:RUNNING IN N/A STATE"

   "MMDB-01:RUNNING IN N/A STATE"

   "POM-01:RUNNING ACTIVE"

   "MEASAGT:RUNNING ACTIVE"

   "OPERSAGT:RUNNING ACTIVE"

   "PROVSAGT:RUNNING ACTIVE"

   "MGCP-1:RUNNING IN N/A STATE"

   "Replic-01:RUNNING ACTIVE"

   "ENG-01:RUNNING ACTIVE"

   "IOCM-01:RUNNING ACTIVE"

   "TCAP-01:RUNNING IN N/A STATE"

   "FOD-01:RUNNING IN N/A STATE"

   "EISUP-1:RUNNING IN N/A STATE"

   "SS7-A-1:RUNNING IN N/A STATE"

---

Note If this MML command is entered on the standby Cisco MGC, the state of the processes is either RUNNING STANDBY or RUNNING IN N/A STATE.

---

Step 2 If any of the processes are initializing, wait a few moments and repeat Step 1. If that process is still initializing, contact the Cisco TAC for assistance. Refer to the "Obtaining Technical Assistance" section for more information on contacting the Cisco TAC.

If any of the processes are stopped, contact the Cisco TAC for assistance. Refer to the "Obtaining Technical Assistance" section for more information on contacting the Cisco TAC.

---

Understanding Processes

The Cisco MGC software contains processes and process groups that perform various functions. These functions include managing the I/O channels; generating alarms, call detail records (CDRs), and logs; and performing signal conversion. All these processes are managed by the process manager process of the Cisco MGC software.

Three different monitoring levels are offered:

•Active process—Controlled and monitored directly by the process manager.

•Passive process—Does not communicate with the process manager.

•Monitoring process—Periodically runs an executable or script and sets or clears an alarm based on the return code. This type of process can monitor other processes or tasks that can be checked programmatically. Some examples are the amount of available disk space, system daemon existence, and established process dependency.

Table 3-1 shows the system processes and process groups controlled by the process manager.

Table 3-1 Processes Controlled by the Process Manager 

Group	Process	Description
ENGG-01		Engine Group
	Replic-01	Replicator controller. It is an active process. If it should go down, it causes a critical out-of-service alarm.

Monitoring the Alarms Status

If you monitor the alarm status of the Cisco MGC continuously, you can determine how often a particular alarm occurs in a specific period of time. To monitor the alarm status of the Cisco MGC on a continuous basis, perform the following steps:

---

Step 1 Log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-alms::cont

The system returns a response that shows all active alarms:

Media Gateway Controller 2000-02-26 11:41:01

M  RTRV

   "LPC-01: 2000-02-26 09:16:07.806,"

   "LPC-01:ALM=\"SCMGC MTP3 COMM FAIL\",SEV=MJ"

   "IOCM-01: 2000-02-26 09:17:00.690,"

   "IOCM-01:ALM=\"Config Fail\",SEV=MN"

   "MGC1alink2: 2000-02-26 09:17:47.224,ALM=\"SC FAIL\",SEV=MJ"

   "MGC1alink3: 2000-02-26 09:17:47.225,ALM=\"SC FAIL\",SEV=MJ"

   "MGC1alink4: 2000-02-26 09:17:47.226,ALM=\"SC FAIL\",SEV=MJ"

   "MGC2alink1: 2000-02-26 09:17:47.227,ALM=\"SC FAIL\",SEV=MJ"

   "MGC2alink2: 2000-02-26 09:17:47.227,ALM=\"SC FAIL\",SEV=MJ"

   "MGC2alink4: 2000-02-26 09:17:47.229,ALM=\"SC FAIL\",SEV=MJ"

   "dpc5: 2000-02-26 09:17:47.271,ALM=\"PC UNAVAIL\",SEV=MJ"

   "ls3link1: 2000-02-26 09:16:28.174,"

   "ls3link1:ALM=\"Config Fail\",SEV=MN"

   "ls3link1: 2000-02-26 09:18:59.844,ALM=\"SC FAIL\",SEV=MJ"

Step 2 If an alarm appears, you can determine the appropriate course of action by referring to the listing for that alarm in the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide. Detailed descriptions of the actions required to resolve the problems associated with the alarm are found in "Troubleshooting the Cisco MGC Node."

You can also find additional information on the conditions that caused the alarms by viewing the system logs. The logs can be viewed using the log viewer, part of the Cisco MGC viewer toolkit. For information on using the log viewer, see the "Using the Log Viewer" section.

---

Note Once you have begun monitoring alarms continuously, you will need to open another MML session to perform any additional tasks. Refer to the "Starting an MML Session" section for more information on starting additional MML sessions.

---

Understanding Alarms

The following subsections describe each of the message components for the typical alarm response shown below:

"LPC-01: 2000-02-26 09:16:07.806,"

"LPC-01:ALM=\"SCMGC MTP3 COMM FAIL\",SEV=MJ"

"IOCM-01: 2000-02-26 09:17:00.690,"

"IOCM-01:ALM=\"Config Fail\",SEV=MN"

"MGC1alink2: 2000-02-26 09:17:47.224,ALM=\"SC FAIL\",SEV=MJ"

"MGC1alink3: 2000-02-26 09:17:47.225,ALM=\"SC FAIL\",SEV=MJ"

Component ID

The first element of the alarm message identifies the system component that generated the alarm, using the customer-defined description of the component given during system configuration. In our example, these are LPC-01, IOCM-01, MGC1alink2, and MGC1alink3.

All system components are described in the Cisco Media Gateway Controller Software Release 7 Provisioning Guide.

Time Stamp

The second element of the alarm message identifies the time of the alarm by year, month, day, hour, minute, hundredths, and thousandths of a second (milliseconds). The time displayed is the system time. In the example, these would be 2000-02-26 09:16:07.806, 2000-02-26 09:17:00.690, 2000-02-26 09:17:47.224, and 2000-02-26 09:17:47.225.

Alarm Category

The third element of the alarm message identifies the alarm category. It indicates the MML description of the alarm/event. In our example:

•ALM=\"SCMGC MTP3 COMM FAIL\" indicates an SCMGC-MTP3 communications failure.

•ALM=\"Config Fail\" indicates a configuration failure.

•ALM=\"SC FAIL\" indicates a signal channel failure.

Severity Level

The last element of the alarm message identifies the severity level of the alarm. The four levels are

•Critical (CR)—A serious problem exists in the network. Critical alarms cause a switchover, where the active Cisco MGC switches processing to the standby Cisco MGC. Because critical alarms affect service, they should be cleared immediately.

---

Caution Critical alarms cause the system to automatically switchover. While a switchover is in progress, new calls are dropped and in-progress calls are sustained.

---

•Major (MJ)—A problem exists that disrupts service. Major alarms should be cleared immediately. These alarms differ from critical alarms in that they do not cause a switchover from the active
Cisco MGC to the standby Cisco MGC.

•Minor (MN)—Minor alarms should be noted and cleared as soon as possible. You might also want to research how often this alarm is appearing, because it may be an indicator of a bigger problem.

•Informational (IN)—This severity level applies to messages that provide information about typical events and conditions. Informational messages do not require corrective action. Examples are timer expirations, values that have exceeded preset thresholds, and unexpected responses from endpoints to signaling messages sent by the Cisco MGC. Events with a severity level of informational are retrieved only by the SNMP Manager.

Verifying the Status of all Destinations

To verify the status of all of the destination point codes (DPCs) provisioned on your Cisco MGC, perform the following steps:

---

Step 1 Log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-dest:all

The system returns a response similar to the following:

   Media Gateway Controller - MGC-04 2000-04-05 08:05:36

M  RTRV

   "dpc1:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

   "dpc2:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

   "dpc3:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

   "dpc4:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

   "dpc5:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

   "dpc6:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

   "eisupftsvc:PKG=EISUP,ASSOC=SWITCHED,PST=IS,SST=UND"

   "eisupsvc1:PKG=EISUP,ASSOC=SWITCHED,PST=IS,SST=UND"

---

Note If the rtrv-dest:all MML command is entered after a switchover has occurred, the state of some of the destinations might be listed as undefined (UND). UND is the default state for a destination when the system starts. In this instance, UND states indicate that the Cisco MGC has not received a service state message from the associated destination since the switchover occurred. No user action is required.

---

Step 2 If the primary service state is not IS for any of the destinations, check your alarms retrieval MML session for signaling-related alarms. The method for setting up an alarms retrieval MML session is described in the "Monitoring the Alarms Status" section.

If a signaling-related alarm appears, you can determine the appropriate course of action by searching for the corrective actions for that alarm in the "Alarm Troubleshooting Procedures" section. If the alarm is not in that section, corrective action is not required. More information on the alarm can be found in the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide.

You can also find additional information on the conditions that caused the alarms by viewing the system logs. The logs can be viewed using the log viewer, part of the Cisco MGC viewer toolkit. For information on using the log viewer, see the "Using the Log Viewer" section.

---

---

Note You can use the also use the rtrv-dest MML command to retrieve information on individual destinations. For more information, refer to the Cisco Media Gateway Controller Software Release 7 MML Command Reference Guide.

---

Understanding the Destination State Information

The following sections describe the information returned by the system when you enter the rtrv-dest command, as in the example below:

"dpc1:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

"dpc2:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

"dpc3:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=UND"

Destination

The first field lists the MML name of the DPC. In the above example, this is dpc1, dpc2, and dpc3

Package

The PKG field lists the protocol package associated with the destination. In the example, the protocol is SS7-ANSI.

Association

The ASSOC field shows the type of association, either unknown, switched, or a specific channel for the destination. In the example, the association type is SWITCHED.

Primary Service State

The PST field shows the current primary service state of the destination. In the example, all of the destinations have a primary service state of IS. Table 3-2 lists the valid primary service state values:

Table 3-2 DPC Primary Service States 

Link State ID	Link State	Description
AOOS	Automatically out-of-service	The system has taken the DPC out-of-service (OOS).
INB	Install busy	When a system is first configured, all signaling links default to this state and must be manually set in-service (IS) through the use of the set-sc-state MML command.
IS	In-service	The link to the DPC is IS and fully operational. This is its normal operating state.
MOOS	Manually out-of-service	The link to the DPC has been manually taken OOS.
OOS	Out-of-service	The link to the DPC is OOS from the remote end. The system is actively trying to restore the link.
TRNS	Transient	The state of the link to the DPC is currently being changed.
UNK	Unknown	The state of the link to the DPC is not known.

Secondary Service State

The SST field shows the current secondary service state of the specified destination. In the example, all of the DPCs have a secondary service state of UND. The valid states are listed below:

•CEA—Commanded into emergency alignment.

•CIS—Commanded in service.

•CONG—Congestion.

•COOS—Commanded out of service.

•CINH—Commanded to the inhibited state.

•CRTE—Created.

•CUINH—Commanded to the uninhibited state.

•DLT—Deleted.

•EIS—Engine in service.

•EOOS—Engine out of service.

•FLD—Failed.

•FOOS—Forced out of service.

•RST—Reset.

•RSTO—Restored.

•UND—Undefined.

---

Note If the rtrv-dest:all MML command is entered after a switchover has occurred, the state of some of the destinations might be listed as undefined (UND). UND is the default state for a destination when the system starts. In this instance, UND states indicate that the Cisco MGC has not received a service state message from the associated destination since the switchover occurred. No user action is required.

---

Verifying State of all SS7 Routes

To verify the status of all of the SS7 routes provisioned on your Cisco MGC, perform the following steps:

---

Step 1 Log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-rte:all

The system returns a message similar to the following:

MGC-01 - Media Gateway Controller 2001-05-22 11:35:46

M  RTRV

   "dpc1:linkset1,APC=244.001.040,PRIO=1,PST=IS,SST=NA"

   "dpc1:linkset2,APC=244.002.040,PRIO=1,PST=IS,SST=NA"

   "dpc2:linkset1,APC=244.001.041,PRIO=1,PST=IS,SST=NA"

   "dpc2:linkset2,APC=244.002.041,PRIO=1,PST=IS,SST=NA"

   "dpc4:linkset1,APC=244.001.044,PRIO=1,PST=IS,SST=NA"

   "dpc4:linkset2,APC=244.002.044,PRIO=1,PST=IS,SST=NA"

Step 2 If the primary service state is not IS for any of the routes, check your alarms retrieval MML session for signaling-related alarms. The method for setting up an alarms retrieval MML session is described in the "Monitoring the Alarms Status" section.

If a signaling-related alarm appears, you can determine the appropriate course of action by searching for the corrective actions for that alarm in the "Alarm Troubleshooting Procedures" section. If the alarm is not in that section, corrective action is not required. More information on the alarm can be found in the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide.

You can also find additional information on the conditions that caused the alarms by viewing the system logs. The logs can be viewed using the log viewer, part of the Cisco MGC viewer toolkit. For information on using the log viewer, see the "Using the Log Viewer" section.

---

Understanding the SS7 Route State Information

The following sections describe the information returned by the system when you enter the rtrv-rte command, as shown in the example below:

"dpc1:linkset1,APC=244.001.040,PRIO=1,PST=IS,SST=NA"

"dpc1:linkset2,APC=244.002.040,PRIO=1,PST=IS,SST=NA"

"dpc2:linkset1,APC=244.001.041,PRIO=1,PST=IS,SST=NA"

"dpc2:linkset2,APC=244.002.041,PRIO=1,PST=IS,SST=NA"

Point Code

The first field lists the MML name for the target point code associated with the SS7 route. In the example, the point codes are dpc1 and dpc2.

Linkset

The second field lists the MML name for the linkset associated with the SS7 route. In the example, the linksets are linkset1 and linkset 2.

Adjacent Point Code

The APC field lists the point code for the adjacent point code (APC) associated with the SS7 route. In the example there are four point codes:

•244.001.040

•244.002.040

•244.001.041

•244.002.041

Priority

The PRIO field lists the priority provisioned for this SS7 route. In the example, all of the SS7 routes have a priority of 1.

Primary Service State

The PST field shows the current primary service state of the destination. In the example, all of the SS7 routes have a primary service state of IS. Table 3-2 lists the valid primary service state values:

Table 3-3 SS7 Route Primary Service States 

Link State ID	Link State	Description
AOOS	Automatically out-of-service	The system has taken the SS7 route out-of-service (OOS).
INB	Install busy	When a system is first configured, all signaling links default to this state and must be manually set in-service (IS) through the use of the set-sc-state MML command.

•ACKD—SS7 Acknowledgement delay

•BSNR—SS7 backward sequence number received (BSNR)

•CIS—Commanded in service

•CONF—Configuration failure

•COOS—Commanded out of service

•ENGR—Call engine reset

•LINK—Link failure

•LINS—Linkset failure

•NA—Cause not available

•OOSPEND—Out of service, pending

•PRHB—SS7 prohibited

•RBLK—SS7 remote blocked

•RCNG—Congestion, remote

•RINH—SS7 remote inhibit

•RSTR—SS7 restricted

•SERR—SS7 signal error

•STBY—Cause standby

•SUPPENT—Supporting entity

•TPATH—Traffic path

•UNK—Cause unknown

Verifying CIC States

We recommend verifying the status of your circuit identification codes (CICs) in groups, to ensure that you have current state information. Retrieving the status of all of your CICs at once can take a while to obtain, and then a long time to page through.

To verify the status of CICs provisioned on your Cisco MGC in groups, perform the following steps:

---

Step 1 Log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-cic:dest_pc:cic=number[,rng=range]

Where:

•dest_pc—MML name of the DPC associated with the CICs to be displayed.

•number—A valid CIC number.

•range—Specifies a range of CICs to be retrieved. The status of all CICs between number and number+range are displayed.

For example, the MML command listed below retrieves bearer channel information for CICs 1-20 on destination point code dpc1:

rtrv-cic:dpc1:cic=1,rng=20

When the Cisco MGC software is used on a nailed network, the system returns a response similar to the following:

   Media Gateway Controller - MGC-04 2000-04-05 08:05:54

M  RTRV

	"dpc1:CIC=1,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=2,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=3,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=4,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=5,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=6,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=7,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=8,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=9,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=10,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=11,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=12,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=13,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=14,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=15,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=16,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=17,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=18,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=19,PST=IS,CALL=IDLE,BLK=NONE"

	"dpc1:CIC=20,PST=IS,CALL=IDLE,BLK=NONE"

When the Cisco MGC software is used on a switched network, the system returns a response similar to the following:

   Media Gateway Controller - MGC-04 2000-04-05 08:05:54

M  RTRV

   "dpc1:CIC=10,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=11,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=12,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=13,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=14,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=15,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

Step 2 If the primary service state is not IS for any of the CICs, or a CIC is blocked, check your alarms retrieval MML session for bearer-related alarms. The method for setting up an alarms retrieval MML session is described in the "Monitoring the Alarms Status" section.

If a bearer channel-related alarm appears, you can determine the appropriate course of action by searching for the corrective actions for that alarm in the "Alarm Troubleshooting Procedures" section. If the alarm is not in that section, corrective action is not required. More information on the alarm can be found in the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide.

Understanding CIC States

The elements of the output from the rtrv-cic MML command is described in the paragraphs that follow.

Circuit Identification

The output of this command identifies the MML name of the associated signaling channel and the number for each CIC.

Primary Service State

The PST field shows the current primary service state of the CIC. Table 3-4 lists the valid primary service state values:

Table 3-4 CIC Primary Service States 

Link State ID	Link State	Description
IS	In-service	The traffic channel or CIC is IS and fully operational. This is its normal operating state.
OOS	Out-of-service	The traffic channel or CIC is OOS from the remote end. The system is actively trying to restore the link. Individual CICs can be OOS even if the destination is IS, due to signaling events such as Q.931 service messages.

Call State

The CALL field identifies the current call state of each CIC. After a call is initiated, a circuit does not return to the Idle (available) state until all related release signaling is satisfactorily completed (the correct release sequence). In and Out call states indicate that the CIC is not available for new calls. Table 3-5 describes the various call states.

Table 3-5 CIC Call States

State	Description
In	Incoming call is in progress. Bearer channel is not available for new call.
Out	Outgoing call is in progress. Bearer channel is not available for new call.
Idle	Circuit is available for use.

Media Gateway State

The GW_STAT field identifies the current state of the media gateway associated with each CIC. Table 3-6 describes the various media gateway states.

Table 3-6 Media Gateway States 

State	Description
CARRIER_FAILURE	A carrier has failed. This is no longer a valid state as of Release 7.4(12).
INTERFACE_FAILURE	This state is valid in Release 7.4(12) and up. An individual CIC has failed. If this state is seen for all CICs associated with a T1 or E1, this indicates that the associated T1 or E1 has failed.
GW_HELD	The call has been held at the media gateway
CXN_IS	The connection is in service
CXN_OOS_ACTIVE	The connection is out of service on the active system
CXN_OOS_STANDBY	The connection is out of service on the standby system

Circuit Block Type

The BLK field identifies the type of circuit block that has been placed on the CIC. Blocked circuits are not available for calls. Table 3-7 describes the valid circuit block types.

Table 3-7 Circuit Block Types

Type	Description
GATEWAY	Locally blocked due to a media gateway event (for example, a media gateway interface fails causing an RSIP message to be sent, but the associated CICs remain in-service or when an RSIP message is not acted upon due to a mismatch between the MGCP host name in the RSIP string and the host name provisioned in the media gateway). If the associated switch is not responding to group unblock messages, the CICs stay in the GATEWAY circuit block state. Your CICs will be in this state when you bring up the Cisco MGC or media gateway. Once the associated switch acknowledges the unblock message, the CICs are taken out of this state. If the CICs stay in the GATEWAY circuit block state, troubleshoot the problem with the media gateway. As of Release 7.4(12), this value is used only for switched systems.
MATE_UNAVAIL	This state is valid in Release 7.4(12) and up, used only in nailed-up systems. Locally blocked due to a media gateway event (for example, a group service message received from the media gateway or the media gateway is out of service). If the associated switch is not responding to group unblock messages, the CICs stay in the MATE_UNAVAIL circuit block state. Your CICs will be in this state when you bring up the Cisco MGC or media gateway. Once the associated switch acknowledges the unblock message, the CICs are taken out of this state. If the CICs stay in the MATE_UNAVAIL circuit block state, troubleshoot the problem with the media gateway.
LOCAUTO	Hardware blocking type—the CIC is blocked by an external message generated by a network element outside the media gateway.
REMAUTO	Remotely automatically blocked.
LOCMAN	Blocked manually using an MML command, such as blk-cic. This is removable using the unblk-cic or reset-cic MML commands.
REMMAN	Remotely blocked manually.
LOCUNK	Locally blocked for unknown reasons. This indicates a potential software problem whereby a CIC has become blocked but the software did not track the cause of the blocking.
COT_FAIL	This state is valid in Release 7.4(12) and up. Blocked because a continuity test failed on the CIC.
INTERFACE_DISABLED	The interface is disabled because the system received a CGB message or a new service has been started which is still in the install busy (INB) state.
NONE	There is no block on the CIC. DS0 is available for use.

---

Note Block types are additive: for example, LOCMAN (locally, manually blocked) and REMMAN (remotely, manually blocked) can both be active at the same time.

---

Verifying Available Disk Space

You should monitor the amount of disk space available on your Cisco MGC on a daily basis. The percentage of disk space capacity used should always be below 90 percent capacity. If your system's percentage of disk space capacity used 90 percent or higher, you must delete files from your disk drive. To verify your available disk space, perform the following steps:

---

Step 1 Log in to the active Cisco MGC, and enter the following UNIX command to check the amount of available disk space on your system:

df -k

The system returns a response similar to the following:

Filesystem            kbytes    used   avail capacity  Mounted on

/dev/dsk/c0t0d0s0    1018191  114909  842191    13%    /

/dev/dsk/c0t0d0s4    2056211  422774 1571751    22%    /usr

If the response to the command indicates a percentage of disk space capacity used 90 percent or higher, you must delete files from your disk drive, as described in the "Deleting Unnecessary Files to Increase Available Disk Space" section.

Step 2 Repeat Step 1 and assess the command response. If the response indicates that the disk space usage is now below 90 percent of its capacity, then this procedure is complete. Otherwise, continue to delete files from your disk drive, as described in the "Deleting Unnecessary Files to Increase Available Disk Space" section, until the disk space usage drops below 90 percent of its capacity.

---

Verifying Available Virtual Memory

The operating system used on the Cisco MGC hosts, Solaris 2.6, is a virtual memory system. A virtual memory system adds to the available memory by writing the contents of an unused block of memory to the disk drive, enabling that block of memory to be used for another purpose. The space on the disk drive dedicated to this function is known as the swap space. Once the data in that block of memory is needed again, the system reads the stored block from the swap space back into memory.

In a typical Cisco MGC installation, the tmp directory (/tmp) is a temporary file system mount that coexists in the same physical disk partition as the swap space. The tmp directory is used to run a number of special files, such as FIFOs, that are required for the system to run properly. As the amount of space allocated to the tmp directory increases, the amount of space available for running Cisco MGC processes decreases, which can cause functional problems. You need to ensure that the amount of space consumed by the tmp directory is kept to a minimum.

---

Caution Do not copy other files into the /tmp directory, such as patches or other software. Use of this directory for temporary storage or for downloading can cause functional problems with the Cisco MGC software.

---

To determine the amount of available virtual memory, you must compare the amount of virtual memory in use to the maximum amount of virtual memory for your system. To do this, perform the following steps:

---

Note Be aware that the time of day at which you enter these commands effects the overall accuracy of the response. If you enter these commands during your busiest hours, the amount of available virtual memory could be quite small, but this may not indicate a need to contact the Cisco TAC.

If this is the case, consider also performing this procedure during a less active call processing time, to determine an average amount of available virtual memory.

---

---

Step 1 The maximum amount of virtual memory is the sum of the physical memory and the size of the swap space. To determine the amount of physical memory on your system, log in to the active Cisco MGC and enter the following UNIX commands:

cd /usr/sbin

prtconf | grep Memory

The system returns a response similar to the following:

Memory size: 512 Megabytes

Step 2 To determine the size of the swap space on the disk drive, enter the following UNIX command:

swap -s

The system returns a response similar to the following:

total: 57944k bytes allocated + 552816k reserved = 610760k used, 1359904k available

Step 3 Add the amount of physical memory to the amount of swap space. This value is the maximum virtual memory for your system.

Step 4 To determine the amount of available virtual memory, enter the following UNIX command:

vmstat 

The system returns a response similar to the following:

procs     memory            page            disk          faults      cpu

 r b w   swap  free  re  mf pi po fr de sr s0 s1 s6 --   in   sy   cs us sy id

 0 0 0   3176 22320   0   1  0  0  0  0  0  0  0  0  0  131  116  104  0  1 99

The amount of swap and free memory listed in the response (3176 and 22,320 in the above example) represents the total amount of available virtual memory. This amount should always be greater than 10 percent of the maximum virtual memory. If this is not the case, proceed to Step 5.

---

Note You also can use this command to check the available virtual memory repeatedly. Enter it in the format vmstat n, where n is the number of seconds between checks. Refer to the man pages on the vmstat command for more information.

When the vmstat command is used to check the available virtual memory repeatedly, you should ignore the first line of output.

---

Step 5 Contact the Cisco TAC for assistance. Refer to the "Obtaining Technical Assistance" section for more information on contacting the Cisco TAC.

---

Verifying Available RAM

You should check the amount of available RAM on the Cisco MGC on a daily basis. To do this, perform the following steps:

---

Step 1 Log in to the active Cisco MGC, and enter the following UNIX command to check the amount of available RAM on your system:

dmesg | grep mem

The system returns a response similar to the following:

mem = 2097152K (0x80000000)

avail mem = 2088370176

If the response indicates that you have plenty of memory available, the procedure is complete. If the response indicates that your system has a small amount of available memory, you may need to add additional memory to your Cisco MGC to handle your system's call processing load.

---

Note Be aware that the time of day at which you enter this command will have an effect on the overall accuracy of the response. If you enter this command during your busiest hours, the amount of available memory could be quite small, but this may not indicate a need to add additional memory.

If this is the case, consider also performing this procedure during a less active call processing time, to determine an average amount of available memory.

---

Step 2 Refer to your Sun Netra documentation for more information on how to add additional memory to a Cisco MGC host.

---

Verifying CPU Utilization Level

You should check the CPU utilization level on the Cisco MGC on a daily basis. To do this, log into the active Cisco MGC and enter the following UNIX command:

ps -ef -o user,pid,pcpu -o args

The system returns a response similar to the following:

va-herring% ps -ef -o user,pid,pcpu -o args

    USER   PID %CPU COMMAND

Check the percentage of CPU resources used for each process (found in the %CPU column). The response from the command represents a snapshot of CPU utilization. We recommend entering the UNIX command repeatedly to construct a more accurate picture of CPU utilization. If a process is using a large amount of CPU resources over a extended period of time, you should contact the Cisco TAC for assistance. Refer to the "Obtaining Technical Assistance" section for more information on contacting the Cisco TAC.

Verifying the Number of Active Processes

You should check the number of active processes on the Cisco MGC on a daily basis. To do this, log into the active Cisco MGC and enter the following UNIX command:

ps -ef

The system returns a response similar to the following:

The response should indicate that there are between 60 and 100 processes active. If the response indicates that there are more than 100 active processes, you should contact the Cisco TAC for assistance. Refer to the "Obtaining Technical Assistance" section for more information on contacting the Cisco TAC.

Verifying the Number of Users

You should check the number of users on the Cisco MGC on a daily basis. To do this, log into the active Cisco MGC and enter the following UNIX command:

who

The system returns a response similar to the following:

mgcusr pts/0        May 29 11:07    (mgcusr-u5.somecompany.com)

mgcusr2 pts/1        May 30 10:05    (mgcusr2-u6.somecompany.com)

Only known login IDs should be listed in the response. If the response indicates that there are unknown login IDs, or login sessions that have lasted a very long time, you should contact the Cisco TAC for assistance. Refer to the "Obtaining Technical Assistance" section for more information on contacting the Cisco TAC.

Verifying Available Memory on the Cisco SLTs

You should check the amount of available memory on your Cisco Signaling Link Terminals (SLTs) on a daily basis. To do this, perform the following steps:

---

Step 1 Log in to a Cisco SLT, and enter the following IOS command to check the amount of available memory:

show mem

The system returns a response similar to the following:

                Head    Total(b)     Used(b)     Free(b)   Lowest(b) Largest(b)

Processor   80CF71E0    16813600     7885028     8928572     8900652 8891892

      I/O    1D00000    19922944     6975904    12947040    12938256 12937500

Ensure that the memory used is less than 90 percent of the total available memory. If this is the case, the procedure is complete. If the response indicates that the Cisco SLT has a small amount of available memory, you may need to add additional memory to the Cisco SLT to handle your system's call processing load.

---

Note Be aware that the time of day at which you enter this command will have an effect on the overall accuracy of the response. If you enter this command during your busiest hours, the amount of available memory could be quite small, but this may not indicate a need to add additional memory.

If this is the case, consider also performing this procedure during a less active call processing time, to determine an average amount of available memory.

---

Step 2 Refer to the "Upgrading DRAM" section for more information on how to add additional memory to a Cisco SLT.

---

Periodic Maintenance Procedures

This section contains procedures that are either performed on automatically, on a scheduled basis, by the system or should be performed by you on a regular basis to keep the Cisco MGC node operating smoothly. You should schedule the procedures that are performed manually as you see fit. These maintenance procedures include

•Automatic Disk Space Monitoring

•Automatic System Log Rotation

•Rotating System Logs Manually

•Creating a Disaster Recovery Plan

•Backing Up System Software

---

Note This section does not include information on maintaining the Sun host server hardware. You should routinely perform general maintenance tasks and diagnostic checks on the host hardware. See the documentation provided by Sun Microsystems, the hardware manufacturer, for detailed information on these types of procedures.

---

Automatic Disk Space Monitoring

The Cisco MGC software includes a script called disk monitor (diskmonitor.sh) that periodically checks the amount of disk space used within the configurable set of disk partitions. Disk monitor ensures that there is sufficient disk space available in each disk partition for the system to continue to operate at peak performance. To do this, disk monitor deletes (trims) the older log files in the /opt/CiscoMGC/var/log and /opt/CiscoMGC/var/spool directories until the disk space usage is within the specified threshold (set using the XECfgParm.dat parameter, diskmonitor.Threshold).

The disk monitor can also track the number of configurations stored in the configuration library (which is found in the /opt/CiscoMGC/etc/CONFIB_LIB directory) and trim the older configurations when the number of configurations exceeds the maximum value you have set in the associated XECfgpParm.dat disk monitor parameter. The process manager runs the disk monitor script once every minute.

The process of administering the configuration library is handled automatically by the Cisco MGC software. The user sets the disk monitor parameter to establish the maximum number of configurations allowed in the configuration library, and the system will trim the older configurations as necessary.

Disk monitor is controlled using the following parameters in the XECfgParms.dat file:

•diskmonitor.Limit—Specifies the number of days to preserve data before trimming is initiated. The default value is 7.

•diskmonitor.OptFileSys —List of optional file systems to monitor. These files are not trimmed by disk monitor.

•diskmonitor.Threshold —Specifies the percentage of disk usage at which alarming and disk trimming is initiated. The default value is 80.

•diskmonitor.CdrRmFinished —Specifies how many days to keep finished (polled) call detail record (CDR) files. The default value is 0, which means that finished CDRs are immediately sent to the spool directory.

•diskmonitor.SoftLimit —Specifies the action to be taken once the number of days threshold set in the diskmonitor.Limit parameter is reached. If this parameter is set to true, disk monitor decrements the value in the diskmonitor.Limit parameter one day at a time (that is, from 7 down to 6, and then down to 5, and so on) until the utilization level drops below the threshold. If this parameter is set to false, disk monitor closes and the system generates a DISK alarm. The files can then be deleted manually. The default value is false.

•diskmonitor.CfgRmDirs—This parameter is added as of release 7.4(11). This parameter specifies the maximum number of configurations that can be stored in the configuration library. The valid values are the range of integers from 3 through 64. The default value is 64. Entering a value outside of the range of valid values disables monitoring of the number of entries stored in the configuration library. If you want to change the value of this parameter, you may need to add it manually to the XECfgParm.dat file.

As of Release 7.4(11), disk monitor performs the following steps in its inspection of disk utilization levels:

1. Verify that the standard and optional partitions, as defined in diskmonitor.OptFileSys, are not over the thresholds for disk utilization or the configuration library, as defined in diskmonitor.Threshold and diskmonitor.CfgRmDirs, respectively.

a. If neither threshold is exceeded, disk monitor exits.

b. If the disk utilization threshold is exceeded, disk monitor attempts to trim the files based on the number of days, as defined in diskmonitor.Limit.

c. If the configuration library threshold is exceeded, disk monitor trims the number of configuration files to match the setting in the diskmonitor.CfgRmDirs parameter, starting with the oldest.

2. Once files are trimmed, disk monitor verifies again that the standard and optional partitions are not over the thresholds for disk utilization and the configuration library.

a. If neither threshold is exceeded, disk monitor exits.

b. If the disk utilization threshold is exceeded, and diskmonitor.SoftLimit is set to false, the disk monitor is exited and a DISK alarm is raised.

c. If the disk utilization threshold is exceeded, and diskmonitor.SoftLimit is set to true, disk monitor begins decreasing the number of days that logs can be stored (the value defined in diskmonitor.Limit), stopping as soon as the disk is under the disk utilization threshold.

d. If the configuration library threshold is exceeded, disk monitor trims the number of configuration files to match the setting in the diskmonitor.CfgRmDirs parameter, starting with the oldest.

If any disk partition exceeds the configurable usage threshold, the Cisco MGC generates a DISK alarm (a major alarm), a warning of a disk partition overrun, and a warning of insufficient disk space. Refer to the "DISK" section for information about the corrective actions required to resolve a DISK alarm.

Some other files, such as call trace files, take up large amounts of disk space and are not trimmed by disk monitor. You may have to periodically delete call trace files. Call trace files are created when you perform call traces as part of troubleshooting a problem. These files can be rather large, and leaving them on your disk could cause problems. For more information about deleting call trace files, refer to the "Deleting Unnecessary Files to Increase Available Disk Space" section.

---

Caution If you are using software prior to Release 7.4(11), we recommend that you limit the number of configuration versions stored in the configuration library to 64. If you are storing a more than 64 system configurations, the state transition can fail during a switchover operation or use of the prov-sync MML command, and the standby Cisco MGC goes to an OOS state. For more information about administering the configuration library, refer to the "Using the Config-Lib Viewer" section.

---

Configuring Disk Monitor

Configuration of the disk monitor can only be done while the Cisco MGC software is turned off. For this reason, disk monitor is typically configured only during the initial installation. For more information on configuring the disk monitor during initial installation, refer to the XECfgParms.dat section of the Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide.

You can perform the configuration after initial installation. To do this, perform the following steps:

---

Caution Performing the following procedure requires that the Cisco MGC software be turned off. Do not attempt the following procedure without the guidance of the Cisco TAC. Refer to the "Obtaining Technical Assistance" section for more information about contacting the Cisco TAC.

If your system uses a single Cisco MGC in a simplex configuration, performing this procedure causes you to drop all calls.

---

---

Step 1 Determine whether any alarms are pending on the active Cisco MGC, as described in the "Retrieving All Active Alarms" section.

If any alarms are pending, you can determine the appropriate courses of action by searching for the corrective actions for those alarms in the "Alarm Troubleshooting Procedures" section. If the alarms are not in that section, corrective action is not required. More information on those alarms can be found in the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide.

Step 2 Repeat Step 1 for the standby Cisco MGC.

Step 3 Modify the disk monitor parameters in the XECfgParm.dat files, which are listed below, on each host, using the procedure described in the "Rebooting Software to Modify Configuration Parameters" section.

•diskmonitor.Limit parameter—Sets the number of days to preserve logged data before trimming is initiated. The default value is 7.

•diskmonitor.OptFileSys—Sets the optional file systems that are checked by the disk monitor script.

---

Note Files in optional directories are not trimmed by disk monitor.

---

•diskmonitor.Threshold—Sets the percentage of disk usage at which alarming and disk trimming is initiated. The default value is 80.

•diskmonitor.CdrRmFinished—Sets the number of days that finished CDR files are kept in the log directory. The default value is 0, which means that finished CDR files are immediately sent to the spool directory.

•diskmonitor.SoftLimit—Determines what action is taken once the number of days threshold set in the diskmonitor.Limit parameter is reached. If this parameter is set to true, disk monitor decrements the value in the diskmonitor.Limit parameter one day at a time (that is, from 7 down to 6 then down to 5 and so on), until the utilization level drops below the threshold. If this parameter is set to false, disk monitor exits and the system generates a DISK alarm. The default value is false.

•diskmonitor.CfgRmDirs—As of Release 7.4(11), you can set the maximum number of configurations that can be stored in the configuration library. The valid values are the range of integers from 3 through 64. The default value is 64. This parameter is not present in the XECfgParm.dat file initially. If you want to modify the value, you must enter the parameter manually into the file.

---

Caution The Cisco MGC software is case-sensitive. Ensure that you enter the parameter name correctly, or the maximum number of configurations will not be modified.

---

---

Note If you want to ensure the proper functioning of the prov-sync MML command, set the diskmonitor.CfgRmDirs parameter to a value between 50 and 60. Entering a value outside of the range of valid values (3 through 64) disables monitoring of the number of entries stored in the configuration library.

---

---

Automatic System Log Rotation

As the system operates, the Cisco MGC software creates the system logs that are stored in a file stored in the /opt/CiscoMGC/var/log directory. The name of the system log file is set by the XECfgParm.dat file parameter, logFileNamePrefix (the default value is platform). The Cisco MGC software stops writing to the current system log file, archives the contents of that file, and commences writing to a new system log file. This process is referred to as log rotation.

Log rotation occurs as a result of one of the following conditions:

•Cisco MGC software startup (the log rotation script is run)

•Log rotation script (log_rotate.sh) is run manually

•The size of the active system log file has exceeded the value set in the XECfgParm.dat parameter, fileRotateSize.

•The time elapsed since the last log rotation has exceeded the value set in the XECfgParm.dat parameter, fileRotateInterval.

When the system rotates the system log file, the current system log file is archived and a new system log file is opened. The archived log file is stored in the $BASEDIR/var/spool directory. Once the Cisco MGC software is up and running, the log server takes over the actual file rotation responsibility of renaming the active file to a historical file with a new file name with the following format: logFileNamePrefix_yyyymmddhhmmss.log, where the time stamp indicates the date/time from the system at the time of rotation.

Rotating System Logs Manually

You can also run the log rotation script manually to force the current system log file to be archived. To do this, log into the active Cisco MGC as root, and enter the following UNIX command:

/opt/CiscoMGC/bin/log_rotate.sh

The system creates a new current system log file and archived log file, as described in the "Automatic System Log Rotation" section.

Creating a Disaster Recovery Plan

You should formulate a disaster recovery plan for your Cisco MGC node to ensure that your system can be restored to service quickly after it has been taken out-of-service by a natural or man-made disaster. A key element in your disaster recovery plan should be ensuring that regular backups of your system's software are performed. Refer to the "Backing Up System Software" section for more information about backup operations. We also recommend that the backup data for your system be stored in a secure location, in a site separate from the equipment, to ensure that they are not affected by the same disaster.

For information on recovering from a natural or man-made disaster, refer to the "Recovering from Cisco MGC Host(s) Failure" section.

Backing Up System Software

You should perform regularly scheduled system software backups on both the active and standby
Cisco MGCs to protect critical system data such as configuration files, which are irreplaceable if lost. If a catastrophic failure occurs, it is much easier to restore system information from backup data than to recreate it. Furthermore, such a failure could cause critical configuration information to be lost if it has not been backed up. We recommend that you create a backup schedule, ensuring that small or incremental backups are performed daily, and a large or full backup once a week.

---

Note We recommend that you back up your system software during periods of low call volume to minimize the effect of the backup on your call processing.

---

There are two backup methods available for the Cisco MGC software, one for software releases up to 7.4(10), and another for software releases from 7.4(11) and up. These backup methods are described in the following sections:

•Backup Procedures for Cisco MGC Software up to Release 7.4(10)

•Backup Procedures for Cisco MGC Software from Release 7.4(11) and up

Backup Procedures for Cisco MGC Software up to Release 7.4(10)

This backup method uses a script to backup the configuration data for the Cisco MGC software on to either a local tape drive or on to a remote machine. This script also allows you to perform full or partial backups. Backup of the Main Memory Database (MMDB) is performed by a separate script. These scripts do not enable you to schedule automatic backup times. You must perform these backups manually.

---

Note If your Cisco MGC is a continuous service system, ensure that you perform backup procedures on both Cisco MGC hosts.

---

The following sections provide the backup procedures:

•Storing a Full Backup Operation on a Local Tape

•Storing a Partial Backup Operation on a Local Tape

•Storing a Full Backup Operation on a Remote Machine

•Storing a Partial Backup Operation on a Remote Machine

•Regular Operations

---

Note The procedures for restoring system data can be found in the "Restoring Procedures for Cisco MGC Software up to Release 7.4(10)" section.

---

Storing a Full Backup Operation on a Local Tape

Use this procedure to store the results of a full backup operation (everything under the base directory) to a tape inserted in the local tape drive. To do this, complete the following steps:

---

Step 1 Log in to the active Cisco MGC as root and change directories to a local subdirectory under the base directory.

For example, enter the following command to change to the /opt/CiscoMGC/local directory:

cd /opt/CiscoMGC/local

Step 2 If your system does not have a dial plan configured, proceed to Step 3. If your system has a dial plan configured, backup the contents of the MMDB to a single file, as described in the "Regular Operations" section.

Step 3 Run the backup script by entering the following command at the UNIX prompt:

./backup.sh

The system returns a response similar to the following:

MGC backup utility

-----------------------------

Destination currently set to Local tape (/dev/rmt/0h)

Enter:

	<N> set destination to remote NFS server

	<L> set destination to Local tape (/dev/rmt/0h)

	<F> for Full (everything you have)

	<P> for Partial (changable part of the system)

	<Q> to quit

Select backup mode: 

Step 4 Enter F and press Enter to start the full backup. The system returns a message similar to the following:

a ./ 0 tape blocks

a ./var/ 0 tape blocks

a ./var/log/ 0 tape blocks

a ./var/log/platform.log 1 tape blocks

a ./var/log/mml.log 1 tape blocks

a ./var/spool/ 0 tape blocks

a ./var/trace/ 0 tape blocks

a ./var/audit_cron.log 1 tape blocks

.

.

.#

Step 5 When the backup operation has finished, remove the tape, engage the write-protect tab, and label the tape "Full MGC Backup." Specify the machine name and the time and date.

---

Storing a Partial Backup Operation on a Local Tape

Use this procedure to store a partial backup operation (the contents of the etc, local, var, and dialPlan subdirectories under the MGC base directory) to a tape inserted in a local tape drive. To do this, complete the following steps:

---

Step 1 Log in to the active Cisco MGC as root and change directories to a local subdirectory under the base directory.

For example, enter the following command to change to the /opt/CiscoMGC/local directory:

cd /opt/CiscoMGC/local

Step 2 If your system does not have a dial plan configured, proceed to Step 3. If your system has a dial plan configured, backup the contents of the MMDB to a single file, as described in the "Regular Operations" section.

Step 3 Run the backup script by entering the following command at the UNIX prompt:

./backup.sh

The system returns a response similar to the following:

MGC backup utility

-----------------------------

Destination currently set to Local tape (/dev/rmt/0h)

Enter:

	<N> set destination to remote NFS server

	<L> set destination to Local tape (/dev/rmt/0h)

	<F> for Full (everything you have)

	<P> for Partial (changable part of the system)

	<Q> to quit

Select backup mode: 

Step 4 Select P and press Enter to start the partial backup. The system returns a response similar to the following:

a ./ 0 tape blocks

a ./var/ 0 tape blocks

a ./var/log/ 0 tape blocks

a ./var/log/platform.log 1 tape blocksL

a ./var/log/mml.log 1 tape blocks

a ./var/spool/ 0 tape blocks

a ./var/trace/ 0 tape blocks

a ./var/audit_cron.log 1 tape blocks

.

.

.

#

Step 5 When the backup operation has finished, remove the tape, engage the write-protect tab, and label the tape "Partial MGC Backup." Specify the machine name and the time and date.

---

Storing a Full Backup Operation on a Remote Machine

Use this procedure to store a full backup operation (everything under the MGC software base directory) to an NFS mountable directory on a remote machine. The remote machine must be set up with an NFS mountable directory that can be written to by the machine being backed up. The NFS setup of the remote machine is beyond the scope of this procedure.

---

Note The remote NFS server you select to store your back up data should be a system in your network that is not used as a Cisco MGC. Storing back up data on a Cisco MGC can negatively affect the performance of the system.

---

To back up the entire Cisco MGC software directory to a remote machine, complete the following steps:

---

Step 1 Log in to the active Cisco MGC as root and change directories to a local subdirectory under the base directory.

For example, enter the following command to change to the /opt/CiscoMGC/local directory:

cd /opt/CiscoMGC/local

Step 2 If your system does not have a dial plan configured, proceed to Step 3. If your system has a dial plan configured, backup the contents of the MMDB to a single file, as described in the "Regular Operations" section.

Step 3 Run the backup script by entering the following command at the UNIX prompt:

./backup.sh

The system returns a response similar to the following:

MGC backup utility

-----------------------------

Destination currently set to Local tape (/dev/rmt/0h)

Enter:

	<N> set destination to remote NFS server

	<L> set destination to Local tape (/dev/rmt/0h)

	<F> for Full (everything you have)

	<P> for Partial (changable part of the system)

	<Q> to quit

Select backup mode: 

Step 4 Select N and press Enter to define the remote NFS server. The system then prompts you for the name of the remote server.

Step 5 Enter the name of the remote NFS server.

Enter server name: remote_hostname

Where: remote_hostname—Name of your desired remote server.

The system then prompts you for the associated directory name on your remote server.

Step 6 Enter the directory name on the remote NFS server.

Enter remote directory : remote_directory

Where: remote_directory—Name of the associated directory on your remote server.

The system then prompts you to select a backup mode.

Storing a Partial Backup Operation on a Remote Machine

Use this procedure to store a partial backup operation (the contents of the etc, local, var, and dialPlan subdirectories under the MGC base directory) to an NFS mountable directory on a remote machine. The remote machine must be set up with an NFS mountable directory that can be written to by the machine being backed up. The NFS setup of the remote machine is beyond the scope of this procedure.

---

Note The remote NFS server you select to store your back up data should be a system in your network that is not used as a Cisco MGC. Storing back up data on a Cisco MGC can negatively affect the performance of the system.

---

To back up a portion of the Cisco MGC software directory to a remote machine, complete the following steps:

---

Step 1 Log in to the active Cisco MGC as root and change directories to a local subdirectory under the base directory.

For example, enter the following command to change to the /opt/CiscoMGC/local directory:

cd /opt/CiscoMGC/local

Step 2 If your system does not have a dial plan configured, proceed to Step 3. If your system has a dial plan configured, backup the contents of the MMDB to a single file, as described in the "Regular Operations" section.

Step 3 Run the backup script by entering the following command at the UNIX prompt:

./backup.sh

The system returns a response similar to the following:

MGC backup utility

-----------------------------

Destination currently set to Local tape (/dev/rmt/0h)

Enter:

	<N> set destination to remote NFS server

	<L> set destination to Local tape (/dev/rmt/0h)

	<F> for Full (everything you have)

	<P> for Partial (changable part of the system)

	<Q> to quit

Select backup mode: 

Step 4 Select N and press Enter to define the remote NFS server. The system then prompts you for the name of the remote server.

Step 5 Enter the name of the remote NFS server.

Enter server name: remote_hostname

Where: remote_hostname—Name of your desired remote server.

The system then prompts you for the associated directory name on your remote server.

Step 6 Enter the directory name on the remote NFS server.

Enter remote directory : remote_directory

Where: remote_directory—Name of the associated directory on your remote server.

The system then prompts you to select a backup mode.

Step 7 Select P and press Enter to start the partial backup. The system returns a response similar to the following:

        Select backup mode: P

a ./ 0 tape blocks

a ./var/ 0 tape blocks

a ./var/log/ 0 tape blocks

.

.

.

backup to va-panthers:/backup/va-blade20000317105337P.tar complete

#

The filename on the remote NFS server is the host name of the machine with the date in YYYYMMDDHHMMSS format and "P.tar" appended.

---

Performing a Backup Operation on the Main Memory Database

Use this procedure to store your dial plan data, which is stored in the MMDB, in a single file.

---

Note If your system is not configured with a dial plan, do not perform this procedure.

---

---

Step 1 Log in to the active Cisco MGC and change directories to a local subdirectory under the base directory.

For example, enter the following UNIX command to change to the /opt/CiscoMGC/local directory:

cd /opt/CiscoMGC/local

Step 2 Run the MMDB backup script by entering the following UNIX command:

./backupDb.sh filename

Where filename is the name of the database backup file.

For example, to backup the contents of the MMDB to a file called dplan, you would enter the following command:

./backupDb.sh dplan

The system returns a response similar to the following:

Exporting database contents for DSN=howdydb into dplan

The Backup process is being initiated for the datastore howdydb

Files for /opt/TimesTen32/datastore/howdydb are being backed up onto standard output

Backup Complete

Backup Procedures for Cisco MGC Software from Release 7.4(11) and up

This backup method uses a script to backup the configuration data for the Cisco MGC software, select UNIX administrative files, and the Main Memory Database (MMDB). This script only performs full backups. This script enables you to perform manual backups, schedule and administer automatic backups, and view a history of the last 30 backup operations performed.

---

Note This functionality is part of a patch to Release 7.4(11). If you want to use this functionality, you must be upgraded to the proper patch level. For more information on verifying the patch level of your system, refer to the "Verifying the Patch Level of the Cisco MGC" section.

---

---

Note If your Cisco MGC is a continuous service system, ensure that you perform backup procedures on both Cisco MGC hosts.

---

---

Note The procedures for restoring system data can be found in the "Restoring Procedures for Cisco MGC Software Release 7.4(11) and up" section.

---

The following sections provide the backup procedures:

•Performing a Manual Backup Operation

•Scheduling an Automatic Backup Operation

•Listing Scheduled Automatic Backup Operations

•Removing an Automatic Backup Operation from the Schedule

•Listing the Backup Operation History

Performing a Manual Backup Operation

To perform a manual backup operation, enter the following UNIX command on the Cisco MGC:

mgcbackup -d path [-r retries -t retry_time]

Where:

•path—The full path of the directory in which to store the backup file, for example a directory on a remote server that you have mounted on your system, or the local tape drive.

---

Note We recommend that you do not store backup files on your local Cisco MGC host, as storage of backup files on the local host reduces the amount of disk space available to process call data, and does not ensure that the data is safe in the event of a natural disaster.

---

---

Note If the path you enter is for a tape device, be aware that a new tape must be entered into the device for each backup. The backup data on a used tape will be overwritten by this operation.

---

•retries—The number of times to check for an active provisioning session on the Cisco MGC, before aborting the backup operation. The default value is 0, and the maximum value is 100.

---

Note A backup operation cannot start while there is an active provisioning session on the
Cisco MGC.

---

•retry_time—The number of seconds to wait between checks for an active provisioning session on the Cisco MGC. The default value is 30 seconds, and the maximum value is 3600 seconds.

For example, to perform a manual backup operation where the backup file is saved to a directory path called /dev/rmt/h0, with a maximum of three attempts, each 60 seconds apart, you would enter the following UNIX command:

mgcbackup -d /dev/rmt/h0 -r 3 -t 60

The backup file is stored in the specified directory path in the following format:

mgc_hostname_yyyymmdd_hhmmss_backup

Where:

•hostname—The name of the Cisco MGC host, such as MGC-01.

•yyyymmdd—The date the backup file is created, in a year-month-day format, such as 20011130.

•hhmmss—The time the backup file is created, in an hour-minute-second format, such as 115923.

Scheduling an Automatic Backup Operation

To schedule an automatic backup operation, perform the following steps:

---

Note You can schedule an automatic backup operation when you are logged in to your system as either root or mgcusr. Any backups scheduled while you are logged in as root cannot be seen while you are logged in as mgcusr. For that reason, we recommend that you always log in as mgcusr when scheduling an automatic backup operation.

---

---

Step 1 Enter the following UNIX command on the Cisco MGC:

mgcbackup -s

The system returns a response similar to the following:

Backup Schedule Menu

--------------------

1. Add a scheduled backup

2. Delete a scheduled backup

3. List scheduled backups

4. Exit

Selection: 

Step 2 Enter 1 to add an automatic backup operation to the schedule.

The system returns a response similar to the following:

Add a Scheduled Backup

----------------------

Enter the name of the backup: 

Step 3 Enter the name of your backup.

---

Note The name of the backup can only be between 1 and 10 alphanumeric characters in length.

---

After you enter the name of your automatic backup, the system returns a response similar to the following:

Enter the directory to place the backup file: 

Step 4 Enter the directory path where you want the backup file stored.

---

Note We recommend that you do not store backup files on your local Cisco MGC host, as storage of backup files on the local host reduces the amount of available disk space to process call data, and does not ensure that the data is safe in the event of a natural disaster.

---

---

Note If the path you enter is for a tape device, be aware that a new tape must be entered into the device for each backup. The backup data on a used tape will be overwritten by this operation.

---

After you enter your directory path, the system returns a response similar to the following:

Enter the number of retries (default=0):

Step 5 Enter the number of times to check for an active provisioning session on the Cisco MGC before aborting the backup operation.

---

Note A backup operation cannot start while a provisioning session is active on the Cisco MGC.

---

---

Note The maximum number of retries is 100.

---

After you enter the number of retries, the system returns a response similar to the following:

Enter the time between retries (default=30 seconds): 

Step 6 Enter the number of seconds to wait between checks for an active provisioning session on the
Cisco MGC.

---

Note The maximum number of seconds between checks is 3600.

---

After you enter the time between attempts, the system returns a response similar to the following:

Enter the day of the week (default=everyday): 

Step 7 Enter the day(s) of the week that you would like the backup operation performed. The following values are valid:

•SUNDAY

•MONDAY

•TUESDAY

•WEDNESDAY

•THURSDAY

•FRIDAY

•SATURDAY

•WEEKDAYS

•WEEKENDS

•EVERYDAY

After you enter your day(s) of the week setting, the system returns a response similar to the following:

Enter the time (HH:MM):

Step 8 Enter the time to start your automatic backup operation, in hour:minute format.

---

Note The range for hour is 00-23, and the range for minute is 00-59.

---

---

Note We recommend that you schedule your automatic backup operation for a time when your system is likely to have a minimum amount of call volume to minimize the effect of the backup on your call processing.

---

After you enter your time setting, the system returns a response similar to the following:

Press enter to continue: 

Step 9 Press enter to return to the backup schedule menu. You can either exit the utility or perform another backup scheduling activity.

---

When the automatic backup operation is performed, the backup file is stored in the specified directory path in the following format:

mgc_hostname_yyyymmdd_hhmmss_backup.tar

Where:

•hostname—The name of the Cisco MGC host, such as MGC-01.

•yyyymmdd—The date the backup file is created, in a year-month-day format, such as 20011130.

•hhmmss—The time the backup file is created, in a hour-minute-second format, such as 115923.

•Displaying Previously Entered MML Commands

•Displaying Information About MML Commands

•Reentering Previously Entered MML Commands

•Retrieving Active MML Sessions

•Ending an MML Session

Displaying Previously Entered MML Commands

You can use the h MML command to redisplay an MML command or a series of MML commands, depending on the number or range that you enter. If you do not enter a number or range, the last MML command entered is displayed.

To redisplay the last MML command entered, log in to the active Cisco MGC, start an MML session, and enter the following command:

h

The system returns a response similar to the following:

Media Gateway Controller  - MGC-01 2000-01-12 15:19:51 

M  RTRV

   "RTRV-TC:ALL"

   /* command 1 */

To redisplay a particular MML command that you entered, log in to the active Cisco MGC, start an MML session, and enter the following command:

h::number

Where number is the number of the MML command you want to display. The last MML command you entered is equal to 1, the command you entered before that would be equal to 2, and so on.

For example, to redisplay the tenth most recently entered MML command, you would enter the following command:

h::10

The system returns a response similar to the following:

Media Gateway Controller  - MGC-01 2000-01-12 15:19:51 

M  RTRV

   "RTRV-SC:ALL"

   /* command 10 */

To redisplay a range of MML command that you entered, log in to the active Cisco MGC, start an MML session, and enter the following command:

h::start_num,end_num

Where:

•start_num—The number of the first MML command you want to display. The last MML command you entered is equal to 1, the command you entered before that would be equal to 2, and so on.

•end_num—The number of the last MML command you want to display.

For example, to redisplay all of the commands from the second to the fifth most recently entered MML commands, you would enter the following command:

h::2,5

The system returns a response similar to the following:

Media Gateway Controller  - MGC-01 2000-01-12 15:19:51

The system would return a response similar to the following:

Media Gateway Controller  - MGC-03 2000-03-20 10:04:28

M  RTRV

   SET-LOG -- Set Logging Levels

   -----------------------------

   Purpose:      This MML command is used to set the logging level of a 

                 process or all processes.  

   Format:       set-log:<proc>:<log level>

                 set-log:all:<log level>

   Input         * proc -- The various actively and passively monitored 

   Description:    processes running on the MGC.  Use the RTRV-SOFTW:ALL 

                   command to display all processes.  

                 * log level -- Sets the logging level for the specified 

                   process. Logging levels are as follows: 

                   -  CRIT  -- Critical level messages.

                   -  DEBUG -- Debug-level messages (lowest level).

                   -  ERR   -- Error condition messages.

                   -  INFO  -- Informational messages.

                   -  WARN  -- Warning condition messages.

                   -  TRACE -- Trace messages.

   Example:      The MML command shown in the following example retrieves 

                 the logging level of the ENG-01 process: 

                 mml> RTRV-LOG:ENG-01

                 Media Gateway Controller  - MGC-01 2000-01-16 09:38:03

                 M  RTRV

                 "ENG-01:DEBUG"

               ;

   Comments:     This command was introduced in Release 7.4. For 

                 information concerning backward compatibility, use the 

                 HELP:CHG-LOG command.  

                 Note: DSKM-01, the disk monitor process, does not make

                 use of log levels and therefore does not accept 

                 log-level change requests.  

To display information on all of the MML commands, log in to the active Cisco MGC, start an MML session, and enter the following command:

help

The system returns a response similar to the following:

Retrieving Signaling Channel Attributes

You can retrieve attributes for an individual signaling channel or linkset, or for all signaling channels and linksets.

To retrieve the attributes for an individual signaling channel or linkset, log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-sc:sig_channel | linkset

Where:

•sig_channel—The MML name of a provisioning component, TDM link, C7 IP link, or IP link.

•linkset—The MML name of a linkset.

For example, to retrieve attributes for a signaling channel called iplink1, enter the following command:

rtrv-sc:iplink1

The system returns a response similar to the following:

   Media Gateway Controller 2000-03-26 20:26:18

   "iplink1:nassvc1,LID=0:IS"

To retrieve attributes for all of the signaling channels and linksets, log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-sc:all

The system returns a response similar to the following, which shows the signaling links to and from the Cisco MGCs and the associated media gateways (different SS7 solutions might use different media gateways).

   Media Gateway Controller 2000-03-26 19:23:23

M  RTRV

   "iplink1:nassvc1,LID=0:IS" /* IP Link 1 for NAS 1 */

   "iplink2:nassvc2,LID=0:IS" /* IP Link 1 for NAS 2 */

   "iplink3:nassvc3,LID=0:IS" /* IP Link 1 for NAS 3 */

   "iplink4:nassvc1,LID=0:IS" /* IP Link 2 for NAS 1 */

   "iplink5:nassvc2,LID=0:IS" /* IP Link 2 for NAS 2 */

   "iplink6:nassvc3,LID=0:IS" /* IP Link 2 for NAS 3 */

   "c7iplink1:ls01,LID=0:IS"  /* Link 1 in Linkset 1 */

   "c7iplink2:ls01,LID=1:IS"  /* Link 2 in Linkset 1 */

   "c7iplink3:ls02,LID=0:IS"  /* Link 1 in Linkset 2 */

   "c7iplink4:ls02,LID=1:IS"  /* Link 2 in Linkset 2 */

Note If a signaling channel is in a state other than IS, attempt to bring it into service, as described in the "Setting the Service State of a Signaling Channel" section

---

Understanding Signaling Channels

Signaling channels are bidirectional transport mechanisms for call-control signaling between the Cisco MGC and other devices, such as the Cisco SLTs, that provide necessary delivery reliability for higher-layer protocols. All types of signaling channels have basically the same functionality and are managed similarly. Unless otherwise noted, all commands, counters, and alarms apply to all types of signaling channels.

The basic types of signaling channels on the Cisco MGC are

•SS7 Message Transfer Part (MTP)—Used for reliable delivery. MTP level 2 provides point-to-point delivery. MTP level 3 maintains multiple load-sharing links and multiple routes between SS7 point codes.

•SS7 MTP over IP (SS7/IP)—MTP level 2 is terminated on the Cisco SLT. MTP level 3 is backhauled to the Cisco MGC by means of the Cisco-proprietary Reliable User Datagram Protocol (RUDP).

•Facility Associated Signaling (FAS)—Found in ISDN PRI or DPNSS over a 64-Kbps channel. Reliable delivery is provided by some form of Link Access Protocol (LAP), for example Q.921.

•FAS over IP (FAS/IP)—Same as FAS, but uses IP as its transport mechanism. Reliable delivery is provided by Q.921 LAP-D or RUDP/SM.

•Media Gateway Control Protocol (MGCP)—Reliable delivery is also provided by the MGCP, which uses UDP/IP.

The following sections describe the information returned by the system when you enter the rtrv-sc MML command.

Signaling channel or linkset name

The first field lists the MML name of the signaling channel or linkset.

Parent Name

The second field lists the MML name of the parent of the signaling channel or linkset.

Link ID

The LID field lists the associated link identification number.

Subsystem Number

The SSN field lists the associated subsystem number.

Primary Service State

The PST field shows the current primary service state of the destination. Table 3-8 lists the valid primary service state values:

Table 3-8 Signaling Channel Primary Service States 

Link State ID	Link State	Description
AOOS	Automatically out-of-service	The system has taken the signaling channel out-of-service (OOS).
INB	Install busy	When a system is first configured, all signaling links default to this state and must be manually set in-service (IS) through the use of the set-sc-state MML command.
IS	In-service	The signaling channel is IS and fully operational. This is its normal operating state.
MOOS	Manually out-of-service	The signaling channel has been manually taken OOS.
OOS	Out-of-service	The signaling channel is OOS from the remote end. The system is actively trying to restore the signaling channel.
TRNS	Transient	The state of the signaling channel is currently being changed.
UNK	Unknown	The state of the signaling channel is not known.

Secondary Service State

The SST field shows the current secondary service state of the specified signaling channel. The valid states are listed below:

•ACKD—SS7 Acknowledgement delay

•BSNR—SS7 backward sequence number received (BSNR)

•CIS—Commanded in service

•CONF—Configuration failure

•COOS—Commanded out of service

•ENGR—Call engine reset

•ISPEND—In service, pending

•LCNG—Congestion, local

•LINE—Line failure

•LINH—SS7 local inhibit

•LINK—Link failure

•LINS—Linkset failure

•NA—Cause not available

•OOSPEND—Out of service, pending

•PRHB—SS7 prohibited

•RBLK—SS7 remote blocked

•RCNG—Congestion, remote

•RINH—SS7 remote inhibit

•RSTR—SS7 restricted

•SERR—SS7 signal error

•STBY—Cause standby

•SUPPENT—Supporting entity

•TPATH—Traffic path

•UNK—Cause unknown

Retrieving Signaling Destination Service States

Retrieving state information about all external point codes and signal paths is a task that performed daily. For more information about this and other daily task refer to the "Daily Tasks" section.

To retrieve information about a specific DPC or non-ISUP signaling service, log in to the active
Cisco MGC, start an MML session, and enter the following command:

rtrv-dest: point_code | sig_srv

Where:

•point_code—The MML name of the DPC.

•sig_srv—The MML name of the non-ISUP signaling service.

The system returns a response similar to the following:

MGC-01 - Media Gateway Controller 2001-06-12 14:53:03

M  RTRV

   "dpc1:PKG=SS7-ANSI,ASSOC=SWITCHED,PST=IS,SST=RCNG"

For more information on the response to this command, refer to the "Understanding the Destination State Information" section.

If the destination is in a primary service state other than IS, attempt to bring it into service, as described in the "Setting the Service State of a Destination" section

---

Note If the rtrv-dest MML command is entered after a switchover has occurred, the state of some of the destinations might be listed as undefined (UND). UND is the default state for a destination when the system starts. In this instance, UND states indicate that the Cisco MGC has not received a service state message from the associated destination since the switchover occurred. No user action is required.

---

Retrieving the Service State of a Linkset

To retrieve the service state of a linkset, log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-lset:linkset

Where linkset is the MML name of the desired linkset.

For example, to retrieve the service state of a linkset called ls1, you would enter the following command:

rtrv-lset:ls1

The system returns a response similar to the following:

Media Gateway Controller  - MGC-01 2000-01-12 15:19:51 

M  RTRV

   IS

The valid service states for a linkset are identical to the primary service state listings for signaling channels, as found in the "Understanding Signaling Channels" section. If the linkset is in any other state than IS, attempt to bring the linkset into service, as described in the "Setting the Service State of a Link or Linkset" section.

   "TCAP-01:TRANS=0"

Clearing TCAP Transactions

To clear all TCAP transactions that are older than a period you specify, log in to the active Cisco MGC, start an MML session, and enter the following command:

clr-tcap-trans::t=number

Where number is the time period, in seconds, after which you want to clear TCAP transactions.

For example, to clear all TCAP transactions that are older than 60 seconds, you would enter the following command:

clr-tcap-trans::t=60

Enabling Blocking/Unblocking Messages

You may want to modify the properties of an IP FAS signaling service to enable your system to send blocking (BLO) and unblocking (UBL) messages when bearer channels go IS and OOS, respectively. The process of modifying the properties of a signaling service is referred to as dynamic reconfiguration. For more information about dynamic reconfiguration, refer to the "Understanding Dynamic Reconfiguration" section.

---

Caution We do not recommend enabling the sending of BLO/UBL messages on your Cisco MGC.

---

---

Note You can use the CMM or the VSPT to enable the sending of BLO/UBL messages on your system. Refer to the Cisco Media Gateway Controller Software Release 7 Provisioning Guide for more information about using the CMM or VSPT to modify the properties of an IP FAS signaling service.

---

To enable your system to send BLO and UBL messages, perform the following steps:

---

Step 1 Start a provisioning session, as described in the "Starting a Provisioning Session" section.

Step 2 Enter the following command to set the property that enables the sending of BLO/UBL messages when bearer channels go IS/OOS, respectively:

prov-ed:ipfaspath:name="comp_name",PropagateSvcMsgBlock=true

Where comp_name is the MML name for the IP FAS signaling service on which you are enabling BLO/UBL messages.

For example, to enable the sending of BLO/UBL messages on an IP FAS signaling service named ipfas1, you would enter the following command:

prov-ed:ipfaspath:name="ipfas1",PropagateSvcMsgBlock=true

Step 3 Save and activate your provisioning changes, as described in the "Saving and Activating your Provisioning Changes" section.

---

Enabling Group Service Reset Messages

You may want to modify the properties of an SS7 signaling service to enable your system to send SS7 group service reset (GSR) messages for all CICs during point code initialization, so that the Cisco MGC to synchronize its bearer channel blocking state with that of the end office. The process of modifying the properties of a signaling service is referred to as dynamic reconfiguration. For more information about dynamic reconfiguration, refer to the "Understanding Dynamic Reconfiguration" section.

---

Caution We do not recommend enabling the sending of GSR messages on your Cisco MGC.

---

---

Note You can use the CMM or the VSPT to enable the sending of GSR messages on your system. Refer to the Cisco Media Gateway Controller Software Release 7 Provisioning Guide for more information about using the CMM or VSPT to modify the properties of an SS7 signaling service.

---

To enable the sending of GSR messages, perform the following steps:

---

Step 1 Start a provisioning session as described in the "Starting a Provisioning Session" section.

Step 2 Enter the following command to set the property that enables the sending of GRS messages for CICs during point code initialization:

prov-ed:ss7path:name="comp_name",GRSEnabled=true

Where: comp_name—MML name for the SS7 signaling service on which you are enabling the sending of GRS messages.

For example, to enable the sending of GRS messages on an SS7 signaling service named ss7svc1, you would enter the following command:

prov-ed:ss7path:name="ss7svc1",GRSEnabled=true

Step 3 Save and activate your provisioning changes as described in the "Saving and Activating your Provisioning Changes" section.

---

Managing Bearer Channels

The operations you can use to manage bearer channels are described in the following sections:

•Verifying Proper Replication of Calls

•Retrieving the States of Bearers Held By a Media Gateway

•Blocking CICs

•Retrieving the Administrative State

Verifying Proper Replication of Calls

Ensure that the standby Cisco MGC becomes fully operational and that the replication of calls in progress has been completed by performing the steps in the following procedure:

---

Caution The following command retrieves the current status of all provisioned traffic channels. If you have a large number of traffic channels, you might want to limit the command to a subset of the provisioned channels, perhaps on a signaling-service-by-signaling-service basis. For example, to see just the provisioned channels for a signaling service named ss7svc2, you would enter the following command: rtrv-tc:name="ss7svc2".

---

---

Step 1 Log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-tc:all

The system returns a different set of responses, depending on which release of the MGC software you are running and the type of configuration you are using on the associated media gateway.

When the Cisco MGC software is used on a nailed network, the system returns a response similar to the following:

   Media Gateway Controller - MGC-01 2000-04-05 08:26:36

M  RTRV

   "dpc1:CIC=1,PST=IS,CALL=IDLE,BLK=NONE"

   "dpc1:CIC=2,PST=IS,CALL=IDLE,BLK=NONE"

   "dpc1:CIC=3,PST=IS,CALL=IDLE,BLK=NONE"

   "dpc1:CIC=4,PST=IS,CALL=IDLE,BLK=NONE"

   "dpc1:CIC=6,PST=IS,CALL=IDLE,BLK=NONE"

   "dpc1:CIC=7,PST=IS,CALL=IDLE,BLK=NONE"

   "dpc1:CIC=8,PST=IS,CALL=IDLE,BLK=NONE"

   "dpc1:CIC=9,PST=IS,CALL=IDLE,BLK=NONE"

When the Cisco MGC software is used on a switched network, the system returns a response similar to the following:

   Media Gateway Controller - MGC-04 2000-04-05 08:05:54

M  RTRV

   "dpc1:CIC=1,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=2,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=3,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=4,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=5,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=6,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=7,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=9,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

---

Note An explanation of the fields in the response can be found in the "Understanding CIC States" section.

---

Step 2 Repeat Step 1 on the standby Cisco MGC.

Step 3 Verify that the CICs in both systems are in sync and show the same status.

Calls in progress should say CALL=IN for both systems.

---

If necessary, you can force the active Cisco MGC to do a maintenance switchover (see the "Performing a Manual Switchover" section) and repeat the above procedure for that system.

Retrieving the States of Bearers Held By a Media Gateway

You can retrieve the states of bearer channels being held by a media gateway. To retrieve the state of a group bearer channels associated with one or more signaling destination(s) that are being held by a media gateway, log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-tc-held:sig_dest| &sign_dest...

Where sig_dest is a logical signaling destination, such as an SS7 point code, FAS path, IP FAS path, or DPNSS path. You can display a complete list of configured components by performing the procedure in the "Retrieving component data" section.

When none of the group of bearer channels associated with the specified signaling destination(s) are being held by a media gateway, the system returns a response similar to the following:

MGC-01 - Media Gateway Controller 2001-06-12 16:28:39

M  RTRV

   "dpc1"

   /* No bearer channels in held state */

When bearer channels associated with the specified signaling destination(s) are being held by a media gateway, the system returns a response similar to the following:

MGC-01 - Media Gateway Controller 2001-06-12 16:28:39

M  RTRV

   "dpc1:CIC=1,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

   "dpc1:CIC=9,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

To retrieve the state of all bearer channels held by a media gateway, log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-tc-held:all

When none of the bearer channels are being held by a media gateway, the system returns a response similar to the following:

Retrieving results.  This could take a few moments...

   "dpc2:CIC=18,PST=IS,CALL=IDLE,GW_STAT=CXN_IS,BLK=NONE"

Blocking CICs

You may need to block a CIC or a range of CICs on your Cisco MGC. Blocking a single CIC causes a BLA message to be sent to the destination SSP. Blocking a range of CICs causes a CGB message to be sent to the destination SSP. The range option only can be used to block CICs within a given trunk (T1 or E1).

To block a single CIC, log in to your active Cisco MGC, start an MML session and enter the following command:

blk-cic:dest_pc:CIC=number

Where:

•dest_pc—MML name of a DPC associated with the CIC you want to block.

•number—The number of the CIC you want to block.

For example, to block CIC number 1, which is associated with a DPC called dpc1, you would enter the following command:

blk-cic:dpc1:cic=1

To block a range of CICs, log in to your active Cisco MGC, start an MML session, and enter the following command:

blk-cic:dest_pc:CIC=number,RNG=range

Where:

•point_code—MML name of a DPC associated with the CICs you want to block.

•number—The number of the first CIC in the range of CICs you want to block.

•range—Specifies the end of the range of CICs to be blocked.

---

Note The Cisco MGC software can be configured to issue individual or group supervision messages for point codes that are associated with an ISUP signaling service. ISUP signaling services issue group supervision messages by default. If an ISUP signaling service is configured to issue individual supervision messages, the range option cannot be used with this command. Blocking of CICs can only be done one CIC number at a time for point codes associated with an ISUP signaling service.

---

For example, to block CIC number 1 through 20, which are associated with a DPC called dpc1, you would enter the following command:

blk-cic:dpc1:cic=1,rng=20

To verify that the CIC(s) have been successfully blocked, retrieve the status of the affected CICs as described in the "Verifying CIC States" section. When you want to return the CIC(s) to service, you must unblock the CIC(s) as described in the "Unblocking CICs" section.

Retrieving the Administrative State

The administrative state refers to the state of CICs (on the Cisco MGC) and spans and bearer channels (on the associated media gateway). There are three possible states: locked, unlocked, and shutdown. You can use the rtrv-admin-state MML command to determine the administrative state of several objects in the Cisco SS7 solution environment, including the Cisco MGC, an associated MGCP media gateway, a trunk group, a signaling service, spans and bearer channels associated with a signaling service (for non-ISUP trunks), and CICs associated with a signaling service (for ISPU trunks).

When you retrieve the administrative state of a object that consists of groups of CICs or spans and bearer channels, you receive an inferred target state, based on the following criteria:

•If all circuits are in a locked state, the inferred target administrative state is locked.

•If at least one circuit is in an unlocked state, the inferred target administrative state is unlocked.

•If the circuits are in a mixture of the locked and shutdown states, the inferred target administrative state is shut down.

If you want to change the administrative state of a component, refer to the "Setting the Administrative State" section.

The following procedures describe how you can use the rtrv-admin-state MML command:

Provisioning your Cisco MGC

The operations you can use to provision your Cisco MGC are described in the following sections:

•Starting a Provisioning Session

•Saving and Activating your Provisioning Changes

•Ending a Provisioning Session Without Activating your Changes

•Invoking Dynamic Reconfiguration

•Retrieving Provisioning Data

•Provisioning a Dial Plan

•Importing Provisioning Data

•Exporting Provisioning Data

•Managing Automatic Congestion Control

For more detailed information about provisioning your Cisco MGC, refer to the Cisco Media Gateway Controller Software Release 7 Provisioning Guide.

Starting a Provisioning Session

You may need to start a provisioning session as part of your system operations. To do this, log into the active Cisco MGC, start an MML session, and enter the following command:

prov-sta::srcver="curr_ver",dstver="mod_ver"

Where:

•curr_ver—The name of the current configuration version. In place of the name of the current configuration version, you can also enter:

–new—A new default session configuration; no existing source configuration is available.

–active—Selects the active configuration as the source for configuration changes.

---

Note If you do not know the name of your current configuration session, you can use the CONFIG-LIB viewer in the MGC toolbar to determine that name. For more information on the CONFIG-LIB viewer, proceed to the "Using the Config-Lib Viewer" section.

---

•mod_ver—A new configuration version name that contains your provisioning changes.

For example, to use a configuration version called ver1 as the basis for a version to be called ver2, you would enter the following command:

prov-sta::srcver="ver1",dstver="ver2"

Once a provisioning session is underway, you may use the prov-add, prov-ed, or prov-dlt MML commands to add, modify, and delete components on your system. If you want to add components to your system, refer to the Cisco Media Gateway Controller Software Release 7 Provisioning Guide. If you want to modify or delete components on your system, refer to the "Invoking Dynamic Reconfiguration" section.

There are two ways to close your provisioning session: saving and activating your provisioning changes, as described in the "Saving and Activating your Provisioning Changes" section or ending your provisioning session without saving and activating your changes, as described in the "Ending a Provisioning Session Without Activating your Changes" section.

Saving and Activating your Provisioning Changes

When you have completed making provisioning changes in your session, you must enter a command to save and activate your changes. There are two different provisioning MML commands that do this: prov-cpy and prov-dply.

---

Caution Using the prov-cpy and prov-dply MML commands can severely impact your system's call processing performance, depending on the extent of your provisioning changes. We recommend that these commands be issued during a maintenance window when traffic is minimal.

---

The prov-cpy MML command is used to save and activate your changes on the active Cisco MGC. This command is typically used to save and activate changes on a Cisco MGC in a simplex configuration. However, you can use the prov-cpy MML command on Cisco MGCs in high-availability or continuous-service configurations, to save and activate your changes on the active Cisco MGC. If you choose to do this, you should enter the prov-sync MML command immediately afterwards, to have your changes saved and activated on the standby Cisco MGC.

---

Note When you enter the prov-cpy command, your provisioning session is also automatically ended. If you want to make additional provisioning changes, you must start a new provisioning session as described in the "Starting a Provisioning Session" section.

---

---

Caution Using the prov-sync MML command can severely impact your system's call processing performance. We recommend that this command be issued during a maintenance window when traffic is minimal.

---

---

Note When the prov-sync MML command is used to synchronize the provisioning settings on the standby MGC host with current settings on the active MGC host, the system does not indicate when the synchronization process has failed.

---

The prov-dply MML command is used to save and activate your changes on the active and standby
Cisco MGCs. This command is typically used to save and activate changes on Cisco MGCs in high-availability or continuous-service configurations. This command should not be used on a Cisco MGC in a simplex configuration.

---

Note When you enter the prov-dply command, your provisioning session is also automatically ended, unless an error occurs during execution. If you want to make additional provisioning changes, you must start a new provisioning session as described in the "Starting a Provisioning Session" section.

---

Ending a Provisioning Session Without Activating your Changes

You may find that you want to end a provisioning session without saving and activating the changes you have entered during your session. If this is the case, you can enter the prov-stp MML command. This command ends your current provisioning session and your changes are not entered.

Invoking Dynamic Reconfiguration

You can dynamically reconfigure, that is modify or delete, select components that you have provisioned on your Cisco MGC. The following procedure lists the sequence of actions you must perform (actual steps to take depend on the provisioning tool you use):

---

Note For more information on which components can be dynamically reconfigured, refer to the "Understanding Dynamic Reconfiguration" section.

---

---

Step 1 Start a provisioning session as described in the "Starting a Provisioning Session" section.

Step 2 Enter the prov-ed or prov-dlt MML commands to change or delete a component. Refer to the Cisco Media Gateway Controller Software Release 7 Provisioning Guide for more information on the specific structure of the command for the component type you want to dynamically reconfigure.

---

Note To change or delete a component, you might have to meet certain preconditions, such as changing the service state of the component to OOS using MML commands (as mentioned in Table 3-9).

---

Step 3 Repeat Step 2 for each component that you want to modify or delete. Refer to the Cisco Media Gateway Controller Software Release 7 Provisioning Guide for provisioning guidelines.

Save and activate your provisioning changes as described in the "Saving and Activating your Provisioning Changes" section.

Step 4 After completing a dynamic reconfiguration operation on the Cisco MGC, you must issue a service message from the associated media gateway to invoke the changes throughout your SS7 solution.

---

Note Refer to the documentation associated with your media gateway for more information on issuing service messages.

---

---

Understanding Dynamic Reconfiguration

Dynamic reconfiguration is a function in the Cisco MGC software that allows you to modify or delete Cisco MGC components while the Cisco MGC software is still in service. Dynamic reconfiguration can be performed without shutting down or restarting either the Cisco MGC software or the Sun host platform.

The Cisco MGC component types that can be dynamically reconfigured are listed below. No other component types can be dynamically reconfigured.

•CICs

•Point codes (DPC, originating point code [OPC], or APC)

•Physical interfaces (TDM, ATM, or Ethernet)

•Signaling links (TDM, ATM, or SS7)

•Signaling services

•SS7 subsystems

•SS7 routes

•Trunk groups

•Component properties (linksets, signaling services, and trunk groups)

Table 3-1 lists the preconditions that must be met for the component before any modification or deletion action can be performed as part of dynamic reconfiguration. There are no preconditions for adding components as part of dynamic reconfiguration.

Table 3-9 Dynamic Reconfiguration Preconditions 

Component	Preconditions
CICs	Call state of the CIC must be IDLE (refer to the "Verifying CIC States" section) and the service state of the associated DPC must be set to OOS (refer to the "Setting the Service State of a Destination" section). or Block type for the CIC must be set to locally blocked (refer to the "Blocking CICs" section) and the associated media gateway span and timeslot must be set to OOS (refer to the documentation for the media gateway). Note In Release 7.4(12), when you add CICs dynamically, you must shutdown and restore the RLM links (using the shutdown and no shutdown commands) on the associated media gateways after you provision the CICs on the Cisco MGC, to bring the CICs in to service. Refer to the documentation for your media gateway for more information on using these commands.
Point codes (DPC, OPC, or APC) and SS7 routes	Service state of the point code and SS7 route must be set to OOS (refer to the "Setting the Service State of a Destination" section).
Signaling links (TDM, ATM, or SS7)	Service state of the signaling link must be set to OOS (refer to the "Setting the Service State of a Link or Linkset" section).
Signaling services	Service state of the signaling service must be set to OOS (refer to the "Setting the Service State of a Signaling Channel" section).
SS7 subsystems	Service state of the subsystems and routes must be set to OOS (refer to the "Setting the Service State of a Local Subsystem Number" section).
Trunk groups Component properties (linksets, signaling services, and trunk groups)	None.

For example, if you want to change the settings for a DPC or remove it altogether, you must first set the service state of the DPC to OOS, before attempting to make changes. If you do not set the service state to OOS, your dynamic reconfiguration request is rejected with an error message.

During dynamic reconfiguration, the system goes through two phases. First, it validates the service states of all objects being changed. If any error is encountered, no reconfiguration takes place on any of the objects. Error messages indicate which components are in error. The format of the error message is "Component's MML name, process rejecting change, reason for rejecting the change, remedy."

If no errors are encountered during the validation phase, the update phase proceeds. This is where the new configuration data is loaded by all of the processes. At the beginning of the update phase, an SNMP alarm is displayed to indicate update starting. At the end of the update phase, the alarm clears, and, if commit/deploy was initiated by MML, the MML response is returned.

To change the current configuration of a component using dynamic reconfiguration, you can only use the provisioning tools provided with the Cisco MGC, MML provisioning commands or an SNMP provisioning agent (such as the Cisco MGC Manager [CMM] or the Voice Services Provisioning Tool [VSPT]).

Provisioning or configuring by using any other means can cause errors during the dynamic reconfiguration process. Using these tools is required because the dynamic reconfiguration process relies on the provisioning tools to validate the data values and, more importantly, to crosscheck the dependencies of the objects. For example, the provisioning tool ensures that adding a signal transfer point (STP) first requires the existence of the associated route.

Retrieving Provisioning Data

You can use the prov-rtrv MML command to retrieve information about your current provisioning settings. The ways in which you can use this command to retrieve provisioning data are described in the following sections:

•Retrieving Data for an Individual Component

•Retrieving Data for All Components

•Retrieving Data for All Components of a Particular Type

•Retrieving Data on the Current Provisioning Session

•Retrieving Data on Supported Signaling Protocols

Retrieving Data for an Individual Component

You can retrieve provisioning data on any individual component on your system. To do this, log in to the active Cisco MGC, start an MML session, and enter the following command:

prov-rtrv:component:name=MML_name

Where:

•component—The MML component type associated with the desired component. You can find a complete list of configured MML component types by performing the steps in the "Retrieving component data" section.

•MML_name—The MML name for the desired component. You can determine the MML names for the various components using the prov-rtrv:all MML command.

For example, to view the provisioning data for a point code called opc, you would enter the following command:

prov-rtrv:ptcode:name="opc"

The system returns a response similar to the following:

MGC-01 - Media Gateway Controller 2000-08-25 16:28:56

M  RTRV

   ""session=active:ptcode"

   /* 

   NAME = opc

   DESC = Originating Point Code

   NETADDR = 201.1.100

   NETIND = 2

   */

The response to the command is dependent upon the component type associated with the desired component. For example, to view the properties for an SS7 signaling service called ss7svc1, you would enter the following command:

prov-rtrv:sigsvcprop:name="ss7svc1"

The system returns a response similar to the following:

MGC-01 - Media Gateway Controller 2001-06-01 10:09:47

Retrieving Data for All Components of a Particular Type

You can retrieve provisioning data on all components of a particular type on your system. To do this, log in to the active Cisco MGC, start an MML session, and enter the following command:

prov-rtrv:component:"all"

Where: component is the MML component type associated with the desired component group. You can find a complete list of MML component types in the Cisco Media Gateway Controller Software Release 7 Provisioning Guide.

For example, to view the provisioning data for all point codes, you would enter the following command:

prov-rtrv:ptcode:"all"

The system returns a response similar to the following:

Provisioning a Dial Plan

You can provision dial plans on your Cisco MGC using the commands listed below. For more information on provisioning and maintaining dial plans, refer to the Cisco Media Gateway Controller Software Release 7 Dial Plan Guide.

•chg-dpl—Reloads dial plans based on customer group ID number.

•numan-add—Adds an element to a dial plan.

•numan-dlt—Deletes an element from a dial plan.

•numan-ed—Edits an existing element in a dial plan.

•numan-rtrv—Displays information pertaining to an element or all elements in a dial plan.

---

Note You can verify dial plans using the translation verification viewer on the Cisco MGC toolbar. For information on using the translation verification viewer, refer to the "Verifying a Dial Plan Translation" section.

---

Importing Provisioning Data

You can import provisioning data files (created using the prov-exp MML command) and execute the MML commands contained in those files in batch mode to copy the set up from another system, or return a system to a baseline configuration. Refer to the "Exporting Provisioning Data" section for more information on exporting provisioning data.

To import the provisioning data files and execute the MML commands in batch mode, log in to the active Cisco MGC, and enter the following UNIX command:

mml -b export_directory_path/filename

Where:

•export_directory_path—The directory path to the location of the exported provisioning data files.

•filename—The name of the provisioning data file you want to import.

The provisioning data files must be provisioned in the following order:

•config.mml—Contains core configuration data (signaling services, SS7 nodes)

•export_trunks.dat (created only when trunks are configured on your system)

•export_trkgrp.dat (created only when trunk groups are configured on your system)

•routing.mml—Contains routing plans

•custGrpID.mml—One of these files is created for each existing dial plan, with the file being named with the associated customer group ID number.

For example, to import the provisioning data stored in the config.mml file, which is located in the /opt/ CiscoMGC/etc/cust_specific/saved_config directory, you would enter the following command:

mml -b /opt/CiscoMGC/etc/cust_specific/saved_config/config.mml

Exporting Provisioning Data

You can use the prov-exp MML command to export the current provisioning set up of your Cisco MGC in MML-command form to a file or files. This allows you to copy the provisioning data from one Cisco MGC and set up another Cisco MGC with that same provisioning data or to restored a Cisco MGC to a baseline provisioning environment. Refer to "Importing Provisioning Data" section for information on importing the provisioning data created by the prov-exp MML command.

To export part of the current configuration of your Cisco MGC to a file, log in to the active Cisco MGC, start an MML session, and enter the following command:

prov-exp:tid:dirname="export_directory_name"

Where:

•tid—Types of data. These can be:

–config—Core configuration data (signaling services, SS7 nodes), including trunks and trunk groups. This selection creates the following files: config.mml, export_trunks.dat (created only when trunks are configured on your system), and export_trkgrp.dat (created only when trunk groups are configured on your system).

–routing—Routing plans. This selection creates a file called routing.mml

–numan—Dial plans. This selection creates a file for each dial plan specified on your system. The file name is dependent on the customer group ID for each dial plan, that is the names of the files follows the format custGrpID.mml.

•export_directory_name—Name of the directory to which the data is exported. This directory is a subdirectory within the /opt/CiscoMGC/etc/cust_specific directory established at installation.

For example, to export the core configuration data to a file stored in the /opt/CiscoMGC/etc/ cust_specific/saved_config directory, you would enter the following command:

prov-exp:config:dirname="saved_config"

To export all of the current configuration of your Cisco MGC to several files, log in to the active Cisco MGC, start an MML session, and enter the following command:

prov-exp:all:dirname="export_directory_name"

Where export_directory_name is the name of the directory to which the data is exported. This directory is a subdirectory within the /opt/CiscoMGC/etc/cust_specific directory established at installation.

The system creates the following files in the specified directory when this command is entered:

•config.mml—Contains core configuration data (signaling services, SS7 nodes)

•export_trunks.dat (created only when trunks are configured on your system)

•export_trkgrp.dat (created only when trunk groups are configured on your system)

•routing.mml—Contains routing plans

•custGrpID.mml—One of these files is created for each existing dial plan, with the file being named with the associated customer group ID number.

For example, to export all of the provisioning data into files stored in the /opt/CiscoMGC/etc/ cust_specific saved_config directory, you would enter the following command:

prov-exp:all:dirname="saved_config"

Managing Automatic Congestion Control

The Cisco MGC supports Automatic Congestion Control (ACC). ACC dynamically regulates incoming traffic on the Cisco MGC to levels that can be handled effectively by rejecting a percentage of new calls when the Cisco MGC is congested. ACC increases the throughput of completed calls through the telephone network during periods of overload.

During periods of overload on the Cisco MGC, a user-defined percentage (depending on internal congestion level) of incoming calls are rejected and an ISUP release message is sent to the adjacent signaling point. That ISUP release message has a clear cause of Switch Equipment Congestion and contains an Automatic Congestion Level (ACL) value that indicates the overload level of the
Cisco MGC. For a call that is in progress when overload occurs and the call clears normally, the ISUP release message has a clear cause of Normal Call Clearing and an ACL value associated with the current overload level of the Cisco MGC.

ACC is controlled by parameters that are found in the XECfgParm.dat file and by a property associated with the signaling service or trunk group, which are described in the following sections:

•Understanding Overload Level Percentage Parameters

•Understanding the CPU Timer Interval Parameter

•Understanding the Maximum ACL Value

•Modifying the Maximum ACL Value

•Retrieving Overload Level

Understanding Overload Level Percentage Parameters

The overload level (or congestion level) of the Cisco MGC is measured in three levels (1, 2, and 3, with 3 being the highest). Each overload level has three associated thresholds, one for overload onset, one for overload abatement, and one more for the percentage of calls that are rejected during an overload condition. These thresholds are defined by parameters found in the XECfgParm.dat file.

The XECfgParm.dat parameters that are used to set the overload level thresholds are listed below.

•Ovl1OnsetThresh—Percentage of total CPU utilization at which overload level 1 is reached. The default value is 82. The range of valid values is 0 through 100.

•Ovl1AbateThresh—Percentage of total CPU utilization at which overload level 1 abates. The default value is 75. The range of valid values is 0 through 100.

•Ovl1RejectPercent—Percentage of calls that are rejected while overload level 1 is active. The default value is 25. The range of valid values is 0 through 100.

•Ovl2OnsetThresh—Percentage of total CPU utilization at which overload level 2 is reached. The default value is 90. The range of valid values is 0 through 100.

•Ovl2AbateThresh—Percentage of total CPU utilization at which overload level 2 abates. The default value is 77. The range of valid values is 0 through 100.

•Ovl2RejectPercent—Percentage of calls that are rejected while overload level 2 is active. The default value is 50. The range of valid values is 0 through 100.

•Ovl3OnsetThresh—Percentage of total CPU utilization at which overload level 3 is reached. The default value is 93. The range of valid values is 0 through 100.

•Ovl3AbateThresh—Percentage of total CPU utilization at which overload level 3 abates. The default value is 85. The range of valid values is 0 through 100.

•Ovl3RejectPercent—Percentage of calls that are rejected while overload level 3 is active. The default value is 100. The range of valid values is 0 through 100.

You can configure the onset, abatement, and rejection thresholds for CPU utilization using these XECfgparm.dat parameters. The default values for these parameters enable the Cisco MGC to operate in conformance with Q.543, section 3. You can modify these values experimentally, based on your network's traffic patterns, to enhance the performance of your Cisco MGC.

---

Note The instructions for modifying the XECfgParm.dat file are found in the Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide.

---

---

Caution Changing the ACC-related parameters in the XECfgParm.dat file requires that the Cisco MGC software be shut down and then re-started. If you decide to modify the parameters in the XECfgParm.dat file, you must contact the Cisco TAC before shutting down the Cisco MGC software.

---

The overload level is tracked using three measurements, which are described in Table 3-10.

Table 3-10 Overload Level Measurement Types 

Measurement	Frequency	Calculation
Mean CPU utilization level	Per CPU utilization interval (user-defined)	Mean of the average CPU utilization levels over the duration of the CPU utilization interval is compared to the overload level thresholds.
Engine thread utilization level	Per CPU utilization interval (user-defined)	Utilization level for the engine thread with the highest average usage level over the duration of the CPU utilization interval is compared to the overload level thresholds. There are three engine threads: •CallProc1 •CallProc2 •Dispatcher Note The number of engine threads is equal to the XECfgParm.dat file parameter, *.numOfThreads, plus 1 ((*.numOfThreads = 2) + 1 = 3).
Call processing engine queue occupancy level	Per new call	Current size of queue is divided by the capacity of the queue and compared to the queue occupancy overload thresholds. The queue occupancy overload thresholds are equal to half of the value of the corresponding overload level thresholds. Note The queue occupancy thresholds are half the value of the overload level thresholds due to the high sensitivity of the measurement. For more information on the CPU utilization interval XECfgParm.dat parameter, refer to the "Understanding the CPU Timer Interval Parameter" section

Overload conditions are most likely to be caused by high CPU utilization levels, since the Cisco MGC software uses multi-threaded processing, which almost eliminates the possibility that the size of the call processing engine queue would exceed the queue occupancy overload thresholds. For information on viewing the current overload level, refer to the "Retrieving Overload Level" section.

When any of the three overload measurement types indicate that an overload onset threshold has been passed, the Cisco MGC generates an alarm associated based on the overload level. Table 3-11 details the overload level to alarm relationship. For more information on these alarms, refer to the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide.

Table 3-11 Alarm Associations for Cisco MGC Overload Levels

Cisco MGC Overload Level	Associated Alarm
1	OverloadLight
2	OverloadMedium
3	OverloadHeavy

The alarms are automatically cleared when the associated overload measurement is re-taken and a new overload level has been reached, either dropping to the associated abatement threshold or rising to a higher onset threshold. For example, if, over three consecutive CPU utilization interval timer periods, the CPU utilization level measurement indicated that the overload level is 3 for the first period, that the overload level is 1 for the second period, and that the overload level is 2 for the third period, the system would go through the following process:

1. CPU utilization interval timer expires, Cisco MGC has an overload level of 3.

2. OverloadHeavy alarm is set.

3. CPU utilization interval timer expires, Cisco MGC has an overload level of 1.

4. The OverloadHeavy alarm is cleared.

5. The OverloadLight alarm is set.

6. CPU utilization interval timer expires, Cisco MGC has an overload level of 2.

7. The OverloadLight alarm is cleared.

8. The OverloadMedium alarm is set.

---

Note It is possible that during the time period for the above example, several overload level alarms associated with an overloaded call processing engine queue could also be set and cleared. Overload level for the call processing queue is determined for each incoming call to protect the system against short-term spikes in the call arrival rate.

---

---

Note The alarms associated with the Cisco MGC's overload level create SNMP traps. To identify these alarms among the SNMP traps, look for the tpAlarmCatName object to contain the name of the alarm (OverloadLight, OverloadMedium, or OverloadHeavy) and the tpAlarmSet object to indicate whether the alarm is being set (2) or cleared (1). For more information on the MIBs for the Cisco MGC, refer to the Cisco Media Gateway Controller Software Release 7 Management Information Base Guide.

---

Understanding the CPU Timer Interval Parameter

The XECfgParm.dat parameter, CPUTimerInterval, is used to specify the interval, in milliseconds, at which the average CPU utilization level of the Cisco MGC is sampled. The default value is 3000. We recommend that you stay within the range of 1000 to 4000 milliseconds. A lower interval rate provides a quicker response to internal congestion, while a higher interval rate provides a more accurate sample.

---

Note The overload level jumps from one level to another, depending entirely on the value of each overload measurement at the time of the sample. The overload level does not step through each level to change from lower-levels to higher-levels or vice-versa.

---

---

Note The instructions for modifying the XECfgParm.dat file are found in the Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide.

---

---

Caution Changing the ACC-related parameters in the XECfgParm.dat file requires that the Cisco MGC software be shut down and then re-started. If you decide to modify the parameters in the XECfgParm.dat file, you must contact the Cisco TAC before shutting down the Cisco MGC software.

---

Understanding the Maximum ACL Value

When the Cisco MGC is overloaded, an ACL value is sent to adjacent signaling points in an ISUP release message. Since ANSI- and ITU-based signaling points have different maximum ACL values, the
Cisco MGC uses a property, MaxACL, associated with an SS7 signaling service or trunk group, to map the ACC maximum overload level value to the maximum ACL value used by the adjacent signaling point.

ANSI-based signaling points have a maximum ACL value of 3, ITU-based signaling points have a maximum ACL value of 2, and the ACC maximum overload level value is 3. When MaxACL is set to 3, the ACC maximum overload value is mapped to the ANSI standard, (the default value for MaxACL is 3). When MaxACL is set to 2, the ACC maximum overload value is mapped to the ITU standard. MaxACL also has a third possible setting, 0, which disables the sending of ACL indications in the ISUP release message. Table 3-12 shows how the MaxACL settings map the ACC maximum overload value to the ANSI and ITU congestion standards.

---

Note Disabling the MaxACL parameter (setting it to `0') does not disable the ACC functionality. If the MaxACL parameter is set to `0' and the Cisco MGC becomes congested, the percentage of calls specified for that overload level are released, and the associated ISUP release message does not contain an ACL indication. The ISUP release message still indicates the proper clear cause.

---

Modifying the Maximum ACL Value

To modify the maximum ACL value using MML commands, perform the following steps:

---

Note You can use the CMM or the VSPT to modify the maximum ACL value on your system. Refer to the Cisco Media Gateway Controller Software Release 7 Provisioning Guide for more information about using the CMM or VSPT to modify the properties of an SS7 signaling service or a trunk group.

---

---

Step 1 Start a provisioning session, as described in the "Starting a Provisioning Session" section.

Step 2 Enter the following command to set the property that maps the internal maximum ACL value to the value expected by the adjacent signaling point:

prov-ed:component:name="comp_name",MaxACL=num

Where:

•component—MML component type name for the SS7 signaling service or trunk group properties. Enter one of the following:

–ss7path—Component type for SS7 signaling services.

–trnkgrp—Component type for trunk groups.

•comp_name—MML name for the SS7 signaling service or trunk group on which you are mapping the internal maximum ACL value to the value expected by the adjacent signaling point.

•num—Number that indicates how to map the maximum ACL values. Table 3-12 lists the valid values for this parameter and their associated congestion levels.

Table 3-12 Maximum ACL Mapping Values 

MaxACL Value	Associated Congestion Standard	Cisco MGC ACC Overload Levels	Corresponding ACL Values
0	N/A	N/A	Disables the creation of ACL
2	ITU	N/A 1 2 3	0 (No ACL present) 1 2 2
3	ANSI	N/A 1 2 3	0 (No ACL present) 1 2 3

For example, to modify the internal maximum ACL value on a trunk group named trunk1, which is adjacent to a signaling point that uses the ITU congestion standard, you would enter the following command:

prov-ed:trnkgrp:name="trunk1",MaxACL=2

For example, to modify the internal maximum ACL value on an SS7 signaling service named ss7svc1, which is adjacent to a signaling point that uses the ITU congestion standard, you would enter the following command:

prov-ed:ss7path:name="ss7svc1",MaxACL=2

Step 3 Save and activate your provisioning changes as described in the "Saving and Activating your Provisioning Changes" section.

---

Retrieving Overload Level

To retrieve the current overload level of your system, log in to the active Cisco MGC, start an MML session, and enter the following command:

rtrv-ovld

The system returns a response that identifies the current overload level (0 through 3) and number of messages in the call engine queue.

Media Gateway Controller  - MGC-01 2000-01-12 15:19:51 

M  RTRV

   "ENGG-01: OVLD=0,MSGQ=0"

Managing your Cisco MGC Platform

The operations you can use to manage your Cisco MGC platform are described in the following sections:

•Performing a Manual Switchover

•Verifying Successful Completion of a Switchover

•Verifying the Patch Level of the Cisco MGC

•Retrieving Configuration Table Data

•Retrieving the Logging Level of Software Processes

Performing a Manual Switchover

In the continuous service configuration, you can swap the roles of the active Cisco MGC and the standby Cisco MGC by invoking the appropriate MML command from the management interface of the active Cisco MGC. A switchover can be done only from the active Cisco MGC, because only the active Cisco MGC can command the standby Cisco MGC to take over. If there is only one Cisco MGC processing all calls, a manual switchover request is rejected.

Manual switchovers are typically performed for the following reasons:

•To periodically switch the roles of the Cisco MGCs

•To upgrade the existing software to a new release

•To bring down a system for hardware maintenance

When you need to order a manual switchover to perform maintenance or upgrade procedures on one or both of the Cisco MGCs, use the following steps or all calls might be killed by the call engine. Starting with both the active and standby Cisco MGCs operating normally, you can invoke a manual switchover from one system to the other by completing the following steps:

---

Step 1 Determine whether both the active and standby Cisco MGCs are operating normally, as described in the "Verifying the Platform State of the Cisco MGC Hosts" section.

Step 2 Determine whether any alarms are pending on either system, as described in the "Monitoring the Alarms Status" section.

If any alarms are pending, you must correct the situation that caused the alarms. Search for the corrective actions required to clear any alarms in the "Alarm Troubleshooting Procedures" section. If the alarms do not appear in that section, corrective action is not required for those alarms. Refer to the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide for more information on those alarms.

Step 3 Ensure that calls are being replicated from the active Cisco MGC to the standby Cisco MGC, as described in the "Verifying Proper Replication of Calls" section.

Step 4 Enter the following MML command to synchronize the provisioning data on the standby Cisco MGC with the data on the active Cisco MGC:

prov-sync

---

Caution Using the prov-sync MML command can severely impact your system's call processing performance. We recommend that this command be issued during a maintenance window when traffic is minimal.

---

Step 5 Determine platform state of both Cisco MGCs, as described in the "Verifying the Platform State of the Cisco MGC Hosts" section.

Step 6 Check that all the processes on the active Cisco MGC are in the running state, as described in the "Verifying That Processes Are Running" section.

---

Caution The next step forces a manual switchover to the standby Cisco MGC. Ensure that the standby Cisco MGC is fully operational and that debugging is turned off before taking the active Cisco MGC OOS, or there might be a total interruption of service.

Switchover can also cause call processing to fail if debugging is turned on.

---

---

Caution If you are using a software version prior to Release 7.4(11), we recommend that you limit the number of configuration versions stored in the configuration library to 64. We recommend this limitation because during a switchover operation or use of the prov-sync command, the standby MGC attempts to synchronize all of its system configurations with those stored in the active Cisco MGC. If you are storing a more than 64 system configurations, the state transition can fail and the standby Cisco MGC goes to an OOS state. For more information about administering the configuration library, refer to the "Using the Config-Lib Viewer" section. If you are using software release 7.4(11) or higher, the disk monitor script automatically controls the number of versions stored in the configuration library. Refer to the Release Notes for the Cisco Media Gateway Controller for more information. For more information about the disk monitor script, refer to the "Automatic Disk Space Monitoring" section.

---

Step 7 Log in to the active Cisco MGC, start an MML session, and enter the following command:

sw-over::confirm

Site alarms are automatically set until the OOS Cisco MGC is returned to an IS state.

Step 8 Verify that the switchover has been successfully performed. To do this, follow the procedure described in the "Verifying Successful Completion of a Switchover" section.

---

Verifying Successful Completion of a Switchover

You can determine whether a switchover (automatic or manual) was successfully completed by retrieving the status of each Cisco MGC. Once all of the processes to come up (the time it takes for this to happen depends on the amount of traffic), determine the platform state of both Cisco MGCs, as described in the "Verifying the Platform State of the Cisco MGC Hosts" section. If the platform state of both Cisco MGCs was as expected, the switchover was successfully completed. If one of the Cisco MGCs does not return the expected platform state, the switchover was not successfully completed. Refer to the "Recovering from a Switchover Failure" section.

Understanding Switchover

Cisco MGCs can be arranged in an Active-Standby configuration in which one MGC host runs active traffic while checkpointing information to the standby Cisco MGC. In the continuous service configuration, the active Cisco MGC is paired with an identical standby Cisco MGC that automatically takes over if a failure or switchover occurs. The continuous service architecture of the Cisco MGC increases the reliability, availability, and failure-aversion capabilities of the system.

The primary goal of the Cisco MGC failover subsystem is to ensure call preservation when there is a system failure. This is achieved by interconnecting two Cisco MGCs while the system carries out the logical functions of call control. At any point, one Cisco MGC is in the active role and the other Cisco MGC is in the standby role. The active Cisco MGC carries out the call control function and updates the standby Cisco MGC about call-processing events. The standby Cisco MGC maintains the same system state (from the call-processing point of view) as the active Cisco MGC. In the event of a critical failure on the active Cisco MGC, the standby switches to the active role and takes over the call control function, ensuring that all established calls are preserved.

---

Note If your system is using a simplex configuration (a single Cisco MGC), or is functioning in standalone mode (the standby Cisco MGC is in the OOS service state), the system cannot perform a switchover. In these instances, the active Cisco MGC remains in the active service state when a critical failure occurs.

---

Switchovers can occur automatically (also known as failovers) when a critical alarm is generated, or a switchover can be performed manually, typically as part of a maintenance or troubleshooting procedure. For more information on performing a manual switchover, refer to the "Performing a Manual Switchover" section.

---

Note When a failover is caused by the temporary loss of all Cisco MGC/IP continuity, the newly standby Cisco MGC can take upwards of 6 minutes to come in-service.

---

Fault-Tolerant Components

The following component processes of the Cisco MGC are fault-tolerant. In other words, each of these processes knows its own state (Active/Standby/Out-of-Service) and the corresponding state of its peer process on the standby system.

•Process manager (procM)—Spawns and manages all processes in the system

•Failover daemon (foverd)—Determines and switches platform states

•Call engine—Handles call-processing functions

•Replicator—Replicates call states from the active Cisco MGC to the standby Cisco MGC

•I/O channel controller (IOCC)—Manages the signaling messages

•I/O channel manager (IOCM)—Manages the protocol-specific IOCCs

Failover Daemon

The active Cisco MGC runs the procM process. ProcM automatically starts when the Cisco MGC is booted and, in turn, starts the alarm manager, configuration manager, call engine, IOCCs, and other processes, including foverd.

The continuous service architecture is controlled by the failover daemon. The failover daemons on both Cisco MGC hosts coordinate the active, standby, and OOS states of those hosts.

The alarm manager process also plays a significant role in a continuous service system. The alarm manager raises the alarm when a critical event occurs and clears the alarm when the condition that caused the alarm is cleared. See the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide for detailed information regarding alarms, specifically which alarms are critical.

The foverd process directs manual switchovers. The switchover configuration provides the following:

•Minimal interruption of service in the event of failure of a single machine

•Maintenance of a consistent configuration on both the active and standby Cisco MGCs

•Avoidance of false switchovers that could cause disruption of service

A critical event is typically a critical process dying or the failure of a subsystem or component that can critically affect call processing. A forced failover occurs automatically when the conditions governing it are met; it is system-initiated and not user-initiated. When a critical event occurs, the alarm manager sends a specific message to the foverd process, indicating the occurrence of the critical event.

When the failover daemon receives notification that a critical event has occurred on the active Cisco MGC, the failover daemon initiates a forced switchover to the standby Cisco MGC. The standby Cisco MGC transitions immediately to the active state; established calls are maintained, but calls still in the process of being set up are lost.

The occurrence of a critical event on system A results in its peer, system B, becoming active while system A goes to an OOS state. Until the critical event that triggered the failover on system A is cleared, its state remains OOS. When the critical event is cleared, the alarm manager sends another message, known as a Clear Alarm message, to the foverd process. The foverd process drives system A to a standby state (if the peer system (B) is still in the active state).

When the critical event is cleared, the failed controller (A) comes back online. It can then become the standby for the currently active Cisco MGC (B). Initially, system A is still OOS. The platform state of system A continues to be OOS until the critical event is cleared.

Established calls are maintained during a switchover because the Call Engine checkpoints call information from the active Cisco MGC to the standby Cisco MGC. In addition, the state of the SS7 network is checkpointed by the MTP3 IOCC. The MTP2 terminal functionality resides on the Cisco SLTs to enable the fault-tolerant MTP3 solution.

The Cisco SLTs are responsible for SS7 MTP2 message processing. The Cisco SLTs communicate directly with the Cisco MGC hosts (active and standby) using RUDP, but they send SS7 traffic only to the active Cisco MGC.

---

Note The number of Cisco SLTs is dependent on the SS7 network traffic load and on link and linkset requirements. It is generally recommended that a minimum of two links per linkset, one link per Cisco SLT, be used to provide SS7 reliability. To further enhance redundancy, it is recommended that the links in a linkset be spread across multiple Cisco SLTs so that any single unit can be removed, added, or serviced without disrupting the SS7 network.

---

Circuit Auditing

An auditing process discovers discrepancies in circuit states between the Cisco MGC and the media gateways it controls. During a switchover, discrepancies might exist as to the state of bearer circuits (CICs) between the newly active Cisco MGC and the bearer devices it controls. Discrepancies in circuit states between the active Cisco MGC and the bearer devices could also occur as the result of control messages to the bearer devices that get lost.

The circuit auditing mechanism can be run periodically at configured intervals or after an automatic or manual switchover. It can also be initiated manually using the MML command, sw-over::confirm. The audit capability is always initiated automatically on indication of critical error conditions from solution components, adjacent SS7 switches, or when critical Cisco MGC conditions occur. The circuit-auditing mechanism detects and resolves circuit state discrepancies that it discovers and resynchronizes the Cisco MGC and the bearer devices.

---

Caution If you are using software prior to release 7.4(11), we recommend that you limit the number of configuration versions stored in the configuration library to 64. We recommend this limitation because during a switchover operation or use of the prov-sync command, the standby MGC attempts to synchronize all of its system configurations with those stored in the active Cisco MGC. If you are storing a more than 64 system configurations, the state transition can fail and the standby Cisco MGC goes to an OOS state. For more information about administering the configuration library, refer to the "Using the Config-Lib Viewer" section. If you are using software release 7.4(11) or higher, the disk monitor script automatically controls the number of versions stored in the configuration library. Refer to the Release Notes for the Cisco Media Gateway Controller Software for more information. For more information about the disk monitor script, refer to the "Automatic Disk Space Monitoring" section.

---

The circuit auditing mechanism is a function of the call engine process in the active Cisco MGC. The call engine subsystem starts a thread to perform the circuit-auditing function upon notification of a switchover event from the fault manager.

The circuit auditing mechanism commands the bearer devices to reflect the circuit state of the Cisco MGC. If a bearer device believes the circuit to be in use and the Cisco MGC does not, the Cisco MGC releases the circuit. However, if the Cisco MGC shows that a bearer circuit is in use and discovers that the bearer device does not show that circuit as in use, the Cisco MGC does not attempt to rebuild the call, but releases all associated resources. Even though the Cisco MGC is the controlling authority, the only course of action when a discrepancy is discovered during a circuit audit is to release all of the allocated resources, which means dropping the call.

Checkpointing

Checkpointing of calls ensures that established calls are preserved in the event of a switchover. The Call Engine sends checkpoint events to the local checkpoint process at one point during call setup and at one point in the call release phase.

Checkpointing is also applied to the following protocol supervisory messages and MML commands that change the logical state of the bearer circuits:

•Blocking and Unblocking Messages and Commands

•Circuit Reset Messages and Commands

The local checkpointing process is responsible for securing these events to disk if the standby Cisco MGC is unavailable and for forwarding those events to the remote checkpointing process once it does become available. If the standby Cisco MGC is running, checkpoint events are batched and forwarded to the remote checkpointing process.

The remote checkpointing process is responsible for handling the checkpoint events from the active Cisco MGC, delivering only established calls to the remote call engine. The remote call engine process begins checkpointing events for calls when it begins active call processing.

The following scenarios are supported:

•Standalone (no standby Cisco MGC available)—You can specify the activation or deactivation of checkpointing. If checkpointing is activated, all checkpoint events are secured to disk.

•Startup (standby Cisco MGC unavailable)—The local checkpointing process retains or secures all events until the standby Cisco MGC is available and a request for synchronization is completed.

•Synchronization—You can request synchronization of the configurations of the two Cisco MGCs. This is required after startup and transition from the standalone Cisco MGC to the standby available configuration.

•Switchover—In the event of a switchover (or failover), the standby Cisco MGC assumes the primary responsibility for processing calls and securing checkpoint events.

Checkpointing is also implemented to support forward Cisco MGC software migration by one release. You can manually take the standby Cisco MGC out of service, upgrade the software to the new release, and resynchronize calls with the active Cisco MGC. For detailed procedures on upgrading the Cisco MGC software, refer to the Cisco Media Gateway Controller Software Release 7 Installation and Configuration Guide.

Verifying the Patch Level of the Cisco MGC

As of Release 7.4(12) of the Cisco MGC software, you can verify the patch level of your Cisco MGC software by performing the following steps:

---

Step 1 Display the current patch level of your system by logging into the active Cisco MGC as root and entering the following UNIX command:

pkginfo | grep Patch

The system returns a response similar to the following:

application CSCOgp003      Cisco Media Gateway Controller Software Patch Package

application CSCOgp009      Cisco Media Gateway Controller Software Patch Package

application CSCOgs003      Cisco Media Gateway Controller Software Patch Package

system      SUNWswmt       Patch Utilities

Look for the Cisco MGC patch with the largest number to determine the current patch level. In the example, the current protocol patch level is patch 9 (CSCOgp009), while the system patch level is patch 3 (CSCOgs003).

---

Note For more information on the patches to the release of the Cisco MGC software you are running, refer to the release notes associated with your release. To determine which release of the Cisco MGC software you are running, enter the rtrv-ne MML command, as described in the "Verifying the Platform State of the Cisco MGC Hosts" section.

---

Step 2 Determine the patches available for your version of Cisco MGC software by entering the following URL on an Internet browser:

http://www.cisco.com/public/sw-center/sw-voice.shmtl

Select your software version from the list and a list of currently available patches displays.

If you find that your patch level matches the current patch level on the web page, the procedure is complete. Otherwise, proceed to Step 3.

Step 3 Download the latest patches and associated installation instruction files to your active Cisco MGC.

Step 4 Open the instruction files and follow the procedures within to install the patches.

Step 5 Once you have installed the new patches, run the check inventory utility to ensure that the patches have installed correctly by entering the following UNIX commands:

---

Caution This utility should not be run while the system is actively processing calls, as it can reduce the call processing rate.

---

---

Note This utility can only be run by a user with root permissions. If you are not logged in as root, you must enter the UNIX command sudo before the utility name to ensure proper execution.

---

cd /opt/CiscoMGC/bin

chk_inv [>file_path]

---

Note You must be in the /opt/CiscoMGC/bin directory to run the check inventory utility.

---

Where file_path is an optional parameter used when you want to redirect the output of the utility to a file. If you do not redirect the output to a file, the results are written to your screen.

For example, to redirect the results of the check inventory utility to a file called inv.out, you would enter the following command:

chk_inv >/opt/CiscoMGC/local/inv.out

Step 6 Review the utility results, either on-screen or by opening the file. If the results indicate that there are no problems with the installation, the procedure is complete. Otherwise, proceed to Step 7.

---

Caution The check inventory utility uses a 32-bit cyclic redundancy check (CRC) to verify your system's software. A 32-bit CRC can have a value anywhere from 1 to over 4 billion. However, there is a slight possibility that two sets of data can have the same CRC value. If this should occur, you will recieve a false positive from the utility.

---

---

Note If the utility results indicate that there is a problem with a part of the software outside of the Cisoc MGC software patch(es), you should determine whether a problem truly exists. The utility compares the software on your system against a master list, and it is possible that your environment may not be using every piece of software on that master list. If the utility indicates that a piece of software is missing, and your system configuration does not use that software, you do not need to load that software. However, if the utility identifies a problem with other software, and your system is using that software, proceed to Step 8.

---

Step 7 Re-install the patch(es), repeating steps 3 through 6. If your second attempt at downloading and installing the patch(es) succeeds, the procedure is complete. Otherwise, proceed to Step 8.

Step 8 Contact the Cisco TAC to further analyze the problem and determine a solution. For more information about contacting the Cisco TAC, refer to the "Obtaining Technical Assistance" section.

Retrieving Measurements

You can view and search the measurements results stored in the measurements log file using the alarm and measurement viewer included in the Cisco MGC viewer toolkit. For more information on viewing and searching measurement files, refer to the "Viewing and Searching System Measurement Files" section.

Each measurement (or counter) is uniquely defined by its measurement category and component identification number. You can retrieve individual measurements using the following MML command from the active Cisco MGC:

rtrv-ctr:comp:"meas_cat"

Where:

•comp—The MML name of the component. A complete list of components can be found in the Cisco Media Gateway Controller Software Release 7 Provisioning Guide. You can retrieve a list of system components by entering the rtrv-cfg:components MML command.

•meas_cat—The desired measurement category. A complete list of measurement categories can be found in "Cisco Media Gateway Controller Measurements". You can retrieve a list of measurement categories by entering the rtrv-cfg:meascategories MML command.

For example, to view the ISUP IAM transmission measurement totals for a component called dpc1, enter the following MML command:

rtrv-ctr:dpc1:"ISUP: XMIT IAM TOT"

The system returns a message similar to the following:

MGC-01 - Media Gateway Controller 2000-07-11 10:15:50

M  RTRV

   "dpc1:CAT=\"ISUP: XMIT IAM TOT\",INT=300,VAL=353"

   "dpc1:CAT=\"ISUP: XMIT IAM TOT\",INT=1800,VAL=2501"

Clearing Measurements

Each measurement (or counter) is uniquely defined by its measurement category and component identification number. You can retrieve individual measurements using the following MML command from the active Cisco MGC:

Using the Cisco MGC Viewer Toolkit

This section describes the various components of the Cisco MGC viewer toolkit. The Cisco MGC viewer toolkit is used to view different types of files on the Cisco MGC. This section describes the various components and the toolkit concept as a whole.

The Cisco MGC viewer toolkit is a suite of viewing tools that were developed to run on the Cisco MGC to provide quick and efficient access to diagnostic and troubleshooting information.

The following viewers are discussed in the following subsections:

•Launching the Cisco MGC Toolbar

•Using the Alarm and Measurement Viewer

•Using the Call Detail Record Viewer

•Using the Config-Lib Viewer

•Using the Log Viewer

•Using the Trace Viewer

•Using the Translation Verification Viewer

•Using the File Options Viewer

•Using the MGC Backup Viewer

•Using the MGC Restore Viewer

The Cisco MGC toolbar (Figure 3-1) is a graphical user interface (GUI) application used to launch the various viewers in the toolkit. Each application runs independently of the others, and there is a button for launching each application in the toolbar.

Figure 3-1 Cisco MGC Toolbar Window

You can run multiple instances of the Cisco MGC toolbar at one time, but only one instance of each tool can be running at a time, and different tools can be run simultaneously. If the selected application is already running, a message is displayed stating that your user ID and the application are already running. There is also a Close button on the toolbar, which is used to close the toolbar; however, closing the toolbar does not stop toolkit applications that are already running.

---

Caution The potential exists for foreground (text) and background (non-text) settings to conflict because your local display settings might conflict with the toolkit's color settings, thus rendering the text within various fields in the toolkit applications unreadable.

If you have problems reading text on any of the toolkit screens, please change the foreground color to a darker color on your display to see if that solves the problem.

---

Launching the Cisco MGC Toolbar

To launch the Cisco MGC toolbar, complete the following steps:

---

Step 1 Log in to the server on which you have installed the Cisco MGC toolkit, and enter the following command:

cd /opt/CMM/bin

Step 2 Enter the following command to launch the Cisco MGC toolbar:

./start.sh tool

The MGC Toolbar window is displayed.

---

Using the Alarm and Measurement Viewer

The alarm and measurement viewer helps you view and search records that reside in the alarm and measurement record logs. The formats of the various alarm and measurement records are specified in the Cisco Media Gateway Controller Software Release 7 Messages Reference Guide. These records are not designed for user reading, but for database loading. These viewers can help you understand these records, and they also provide useful searching functions based on the components and categories you select.

The alarm and measurement viewer offers a help file, which contains information about the viewer. To access the information, click the Help menu, select ReadMe, and the help text is displayed. You can also use this viewer to determine the current timestamp. To do this, click the Time menu, select TimeStamp. The current timestamp is displayed in a window.

You can exit the Alarm and Measurement Viewer in one of two ways: in the Query Criteria portion of the window, click Exit, or from the File menu, select Exit.

Viewing and Searching System Measurement Files

Complete the following steps to view and search various system measurement files:

---

Step 1 Open the alarm and measurement viewer. To do this, click Alarm&Meas Viewer on the Cisco MGC Toolbar. A popup window displays warning you that running this tool can impact system performance and asking you if you want to launch the tool. Click Yes. The Alarm & Measurement Viewer window loads and displays the Meas Record View tab window by default (Figure 3-2).

Step 2 Select the system measurement file(s) you want to display from the field to the right of the Query Criteria portion of the window.

Figure 3-2 Meas Record View Tab Window

You can select multiple files in this field using any of the following techniques:

•Select a range of files by clicking a file, holding the mouse button down, dragging the mouse pointer down to the last file you would like to select, and letting go of the mouse button.

•Select a range of files by holding down the Shift key, clicking the first file in the range, clicking the last file in the range, and releasing the Shift key.

•Select multiple files not located next to each other by holding down on the Ctrl key and clicking each file you want to include.

Step 3 To search by a component, select a component type from the CompType drop-down list box. If you do not want to search by a component or you want to view the entire content of the file(s), select the NO_SPECIFIC entry.

Click CompList to acquire the configured components for the type you selected. The results are displayed in the drop-down list box next to the button. Select a component from that list box.

Step 4 To search by a category, select a category type from the catType drop-down list box. If you do not want to search by a category or you want to view the entire content of the file(s), select the NO_SPECIFIC entry.

Click measList to acquire the configured categories for the type you selected. The results are displayed in the drop-down list box next to the button. Select a category from that list box.

Step 5 Click Execute to search the selected system measurement file(s). The results of the search are displayed as blue text in the field at the bottom of the window.

Step 6 If you want to perform additional searches, repeat steps 2 to 5. The color of the text from the old search changes from blue to black and the newly requested search data is inserted as blue text, appearing after the old data. Scroll down through the field to view the data you have added (You can clear the display field by clicking Clear before you click Execute, if you no longer require the previously requested data).

Step 7 If you want to save the displayed data, click Save. The contents of the field are saved to a file with the following directory path:

$BASEDIR/etc/cust_specific/toolkit/measRec.log

If you perform another search and save the resulting content, the contents of the field are added into the measRec.log file, after the previously saved data. If you do not want the data to be added onto the previous data, you must change the name of the measRec.log file before you save again. To change the name of a file, refer to the procedures in the "Using the File Options Viewer" section.

If you do not find your desired data, you can update the list of system measurement files by clicking Refresh. Repeat the above steps to search through the newest files.

---

Viewing and Searching Alarm Record Files

Complete the following steps to view and search various system alarm files:

---

Step 1 Open the alarm and measurement viewer. To do this, click Alarm&Meas Viewer on the Cisco MGC Toolbar. A popup window displays warning you that running this tool can impact system performance and asking you if you want to launch the tool. Click Yes. The Alarm & Measurement Viewer window loads and displays.

Step 2 Click the Alarm Record View tab. The Alarm Record View tab window displays (Figure 3-3).

Step 3 Select the alarm file(s) you want to display from the field to the right of the Query Criteria portion of the window.

You can select multiple files in this field using any of the following techniques:

•Select a range of files by clicking a file, holding the mouse button down, dragging the mouse pointer down to the last file you would like to select, and letting go of the mouse button.

•Select a range of files by holding down the Shift key, clicking the first file in the range, clicking the last file in the range, and releasing the Shift key.

•Select multiple files not located next to each other by holding down on the Ctrl key and clicking each file you want to include.

Using the Call Detail Record Viewer

CDRs contain basic call billing information, such as date and time, duration, and the calling number and called number. CDR records are written into files that contain information about telephone activity. CDR files are saved in a comma-delimited format (called a "Tag-Length-Value" or TLV file). The TLV file is a generic format that can be easily imported into most third-party mediation applications.

The CDR dumper (see Figure 1-1) provides logging capabilities on the Cisco MGC for all CDRs. Also, the CDR dumper supports external user application programming interfaces (APIs). The APIs allow users to get a real-time feed of CDRs and call detail blocks (CDBs) from the Cisco MGC that can be routed to a third-party mediation application for use in billing.

The CDR dumper operates according to the configuration set up in the XECfgParm file. When certain thresholds are met, the CDR dumper closes and saves the generated CDB records into the $BASEDIR/var/spool directory. It then passes the filename and fork to the TLV converter application.

The CDR viewer is designed to help you view and search call detail records that reside in the CDR logs. The formats of the CDBs and call data elements (CDEs) that comprise CDRs are specified in the Cisco Media Gateway Controller Software Release 7 Billing Interface Guide. These records are designed for database loading, not user reading. The CDR Viewer can help you understand these records, and it also provides useful searching functions based on the search criteria you select.

---

Note Your screen might be slightly different from this example, depending on which release of the software you are running.

---

You can exit the CDR viewer in one of two ways: in the Query Criteria portion of the window, click Exit, or from the File menu, select Exit.

Configuring the CDR Viewer

Whenever you start the CDR viewer, you must select several configuration settings before you can view or search the CDR files. To do this, complete the following steps.

---

Step 1 Open the CDR viewer. To do this, click CDR Viewer on the Cisco MGC Toolbar. A popup window displays warning you that running this tool can impact system performance and asking you if you want to launch the tool. Click Yes. The CDR Viewer window loads and displays.

Step 2 Click the Config tab. The Config tab window displays (Figure 3-4).

The first five fields in the window cannot be modified. These fields list the directory paths and file names for the related data files.

Step 3 You can modify the directory path and file name for the file in which any CDR search results can be saved. To do this, click in the Search Result Log File field and change the displayed information.

Figure 3-4 Config Tab Window

---

Note We recommend that you not use this field to change the directory information for the CDR search results file.

---

Step 4 You can also set the source for your CDR information to either a local or remote host.

If you want to use a local host as your source for CDR information, click the Source CDRs From Local check box and proceed to Step 5.

If you want to use a remote host as your source for CDR information, click the Source CDRs From Remote check box and proceed to Step 6.

---

Note If you change your CDR source from local to remote, the tab for the ConnHost window (Figure 3-5) appears. If you change your CDR source from remote to local, the tab for the ConnHost window disappears.

---

Figure 3-5 ConnHost Tab WIndow

Step 5 You can modify the CDR source directory on your local host. To do this, click in the CDR Data Dictionary on Local Host field and change the displayed information.

Proceed to Step 11 to select the message type(s) for which you are searching.

Step 6 You can modify the CDR source directory on your remote host. To do this, click in the CDR Directory on Remote Host field and change the displayed information.

Step 7 Click the ConnHost tab to display the ConnHost tab window (Figure 3-5).

Step 8 You can add or modify the name of the remote host. To do this, select the From Remote Host field and enter the name of the remote host you want to use a source for your CDR files.

Step 9 If you add or modify a remote host name, you must enter user account information for the viewer to use in accessing the host. To do this, enter the appropriate user name and password data in the User Name and Password fields, respectively.

Step 10 You can modify how frequently the CDR viewer checks the remote host for new CDB files. To do this, enter the value you want (in minutes) in the Remote Host CDR Collection Interval(Min) field.

If you set the interval value above zero, after you click Connect, you are notified by a popup message box when new CDB files are deposited on the remote host. You can click OK in the message box to dynamically update the CDB files on the local host, or you can click NO to keep the local CDB file directory as it is.

If you set the interval value to zero, you are not notified of file changes on the remote host, and the CDB files on the local host are not dynamically updated.

The FileDumpCriteria(0=NoLimit) field displays the configuration information for CDRs on the Cisco MGC. This content of this field cannot be modified.

Step 11 You must specify the message type(s) for which you are searching. To do this, click the Config tab to display the Config tab window (Figure 3-4), and select the message type(s) you are looking for in the All Possible Message Types field. Click the right arrow button and the specified message type(s) are displayed in the Selected filtering field.
