Changes to Cisco MGC Software Architecture

This section describes the changes to Cisco MGC software architecture to support this feature.

Input/Output Subsystem

The Input/Output (I/O) subsystem consists of the I/O channel controllers (IOCC) and the I/O channel manager (IOCM), which manages them.

The IOCM manages all IOCCs and keeps the hardware resource states of the hardware controlled by the IOCCs.

The IOCCs provide

A protocol-specific, message-based interface that allows nodes and platforms external to the Cisco MGC to communicate with the Cisco MGC.

An interface that allows buffering of messages to the call engine's event dispatcher queue.

The Cisco MGC I/O subsystem includes the following IOCCs:

Signaling System 7 (SS7)—Contains MTP3 used for backhauling SS7 signaling to the
Cisco MGC from a Cisco SLT.

ISDN Level 3—Provides backhauling of ISDN (standard variants) to the Cisco MGC from a media gateway.

Q.931+—A stateless IOCC, for a Cisco-proprietary protocol (RLM), which is a special version of ISDN that enables forwardhauling of Q931+ signaling to a media gateway used with a Cisco PGW 2200 configured for signaling environments.

Media Gateway Control Protocol (MGCP)—Enables communication to media gateways and trunking gateways for setting up bearer channel connections used in Cisco PGW 2200 configured for call control environments.

Extended ISDN User Part (E-ISUP)—Cisco-proprietary internal interface that enables the transport of endpoint and media gateway specific information between two (or more) Cisco MGCs. This protocol uses an enhanced ISUP base to support all ANSI and ITU ISUP messaging and elements, as well as additional fields to support transport of service information (such as local number portability (LNP), 800 numbers, and so on).

Session Initiation Protocol (SIP)—Enables the Cisco MGC to receive and send SIP messages using the User Datagram Protocol (UDP).

Transport Adapter Layer Interface (TALI)—Enables communication between the Cisco MGC and the Tekelec IP7 Secure Gateway signaling gateway. One TALI IOCC can communicate with up to two Tekelec IP7 Secure Gateways.

IUA—Added in Release 9.4, this IOCC enables backhauling of ISDN Q.921 User messages over IP using SCTP. This IOCC is used between a Cisco PGW 2200 and media gateways.

Message Transfer Part Level 3 (MTP3) User Adaptation (M3UA)—Added in Release 9.4, this IOCC enables the transport of any SS7 MTP Level 3 User signaling (for example, ISUP and TUP messages) over IP using SCTP. This IOCC is used between a Cisco PGW 2200 and Cisco ITP.

Signaling Control Connection Part (SCCP) User Adaptation (SUA)—Added in Release 9.4, this IOCC enables the transport of any SCCP user signaling (for example, TCAP messages) over IP using SCTP. This IOCC is used between a Cisco PGW 2200 and Cisco ITP.

(DPNSS)—Added in Release 9.4, this IOCC enables the tranparent transport of DPNSS data over IP. This IOCC is used between media gateways that support DPNSS.

Prerequisites

You must have Cisco Media Gateway Controller (MGC) software Release 9.4(1). Prerequisites for this release can be found in the Release Notes for the Cisco Media Gateway Controller Software Release 9.4(1).

Configuration Tasks

This sections contains the steps necessary for configuration of the Cisco MGC software to support this feature. For information on installing and configuring the Cisco MGC software on your system, refer to the Cisco Media Gateway Controller Software Release 9 Installation and Configuration Guide, coming back to this section once you encounter the *.IP_NextHop1 parameter in the XECfgParm.dat file.


Note You only need to configure the *.IP_NextHop parameters when the Cisc o MGC hosts are on different subnets. If your hosts are on the same subnet, do not perform the procedure below.



Caution Configuration of the Cisco MGC software requires that the system software be shut down. In a simplex system, calls cannot be processed during system shut down. In a continuous service system, your system loses the ability to maintain calls during a critical event while the system software on one of the PGW hosts is shut down.


Caution The other XECfgParm.dat parameters associated with this feature should not be modified.

To configure the next hop IP addresses, perform the following steps:


Step 1 If you have not already done so, open the /opt/CiscoMGC/etc/XECfgParm.dat file on the active and standby Cisco PGW hosts using a text editor, such as vi.

Step 2 If you have not already done so, ensure that the pom.dataSync parameter is set to false on the active and standby Cisco PGW hosts.

Step 3 Search for the *.IP_NextHop1 parameter and enter the IP address of your first next hop destination on the active and standby Cisco PGW hosts.


Note The IP address should be expressed in decimal dot notation (for example, 10.25.81.5).


Step 4 Repeat Step 3 for every next hop destination (*.IP_NextHop2, *.IP_NextHop3, etc.) you want to identify on the active and standby Cisco PGW hosts. Up to eight next hop IP addresses can be specified.

Step 5 Return to the Cisco Media Gateway Controller Software Release 9 Installation and Configuration Guide and continue from where you left off. You will need to go to the "Adding DPNSS Connections" section in this document later if you intend to use an IUA interface for data backhaul between your Cisco PGW 2200 and your associated Cisco access server(s).


Troubleshooting Tips

If the next hop IP addresses you have entered are incorrect, perform the following steps. For more information on troubleshooting the rest of the Cisco MGC software, refer to the Cisco Media Gateway Controller Software Release 9 Operations, Maintenance, and Troubleshooting Guide.

To ensure proper functioning of this feature, you must enter next hop IP addresses in the XECfgParm.dat file. These IP addresses are used when the next hop router IP addresses on the Cisco PGW hosts do not match. To enter next hop IP addresses, perform the following steps:


Caution The other XECfgParm.dat parameters associated with this feature should not be modified.


Step 1 Log in to the standby Cisco MGC as root and change directories to the etc subdirectory by entering the following UNIX command:

cd /opt/CiscoMGC/etc

Step 2 Open the XECfgParm.dat using a text editor, such as vi.

Step 3 Search for the *.IP_NextHop1 parameter and enter the IP address of your first next hop destination.


Note The IP address should be expressed in decimal dot notation (for example, 10.25.81.5).


Step 4 Repeat Step 3 for every next hop destination (*.IP_NextHop2, *.IP_NextHop3, etc.) you want to identify. Up to eight next hop IP addresses can be specified.

Step 5 Save your changes and close the text editor.

Step 6 Manually stop the Cisco MGC software on the standby Cisco MGC by entering the following UNIX command:

/etc/init.d/CiscoMGC stop

Step 7 Once the software shutdown is complete, manually start the Cisco MGC software on the standby Cisco MGC by entering the following command:

/etc/init.d/CiscoMGC start

Step 8 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 PGW host is returned to an IS state.

Step 9 Repeat steps 2 through 8 for the newly standby Cisco PGW host.

Provision the transport path for DPNSS data between the Cisco PGW 2200 and the external Cisco access server nodes. Communication between the Cisco PGW 2200 and the Cisco access servers is provisioned to provide a reliable communication path between the two platforms.

This provisioning is performed when an external node is modified to use an SCTP-based protocol or when a new external node is added to the Cisco PGW 2200. This section covers the following provisioning topics:

Provisioning Basics

Adding DPNSS Connections

Modifying DPNSS Components

Deleting DPNSS Components

Provisioning Basics

The procedures in this section describe how to start a provisioning session and how to save and activate the changes you have made.

Starting a Provisioning Session

Saving and Activating your Provisioning Changes

Ending a Provisioning Session Without Activating your Changes

Retrieving Provisioning Data

For more detailed information about provisioning your Cisco PGW 2200, refer to the Cisco Media Gateway Controller Software Release 9 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 procedure in the "Retrieving Data on the Current Provisioning Session" 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. This document describes how to add, modify, and delete M3UA and SUA components. For more information on provisioning other components on your Cisco PGW 2200, refer to the Cisco Media Gateway Controller Software Release 9 Provisioning Guide.

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.

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 Select 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 MML component types in the Cisco Media Gateway Controller Software Release 9 Provisioning Guide.

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 an IUA signaling service called iua1, you would enter the following command:

prov-rtrv:sigsvcprop:name="iua1"

The system returns a response similar to the following:

<<get system response>>

Retrieving Data for Select Components

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

prov-rtrv:all


Note This command returns data on all signaling components, except for signaling service and linkset properties.


The system returns a response similar to the following:

<< get system response >>

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 9 Provisioning Guide.


Note Components that are used to retrieve signaling or routing properties (that is sigsvcprop, lnksetprop, and trnkgrpprop) cannot use this command. The properties for only one signaling or routing component can be listed per command instance. Please use the following format:

prov-rtrv:propComp:name="compName" | name="ss7famName"

Where:

propComp—MML component name appropriate to the property type you want to retrieve, as listed below:

sigsvcprop—Provides maintenance access to the properties of signaling services.
trnkgrpprop—Provides maintenance access to the properties of trunk groups
lnksetprop—Provides maintenance access to the properties of linksets.

compName - MML name of a previously provisioned signaling service or trunk group.
ss7famName - MML name of the SS7 family associated with the desired linkset.


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

prov-rtrv:naspath:"all"

The system returns a response similar to the following:

<< get system response >>

Retrieving Data on the Current Provisioning Session

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

prov-rtrv:session

The system returns a response similar to the following:

MGC-02 - Media Gateway Controller 2003-01-13 13:39:19
M  RTRV
   "session=jtest:session"
   /*
Session ID = mml1
SRCVER = active
DSTVER = jtest
   */

Retrieving Data on Supported Signaling Protocols

You can retrieve protocol data for the current provisioning session. To do this, log in to the active
Cisco MGC, start an MML session, and enter the following command:

prov-rtrv:variants

The system returns a response similar to the following:

<< get system response >>

Adding DPNSS Connections

This section contains the procedures that you must perform to add DPNSS connections to your Cisco PGW 2200 provisioning data. When provisioning the components that enable the Cisco PGW 2200 to support DPNSS, perform the procedures in the following order.

IPADDR1="IP_Addr1", IPADDR2="IP_Addr2", PEERADDR1="10.82.80.187", 
PEERADDR2="10.82.81.164", extnode="va-3600-37, IPROUTE1="iprte1", IPROUTE2="iprte2"


Note The parameters listed above are those required to create an SCTP association for an IUA interface. For a complete list of parameters for this component, refer to the "SCTP Association" section.


Step 3 Repeat Step 2 for each SCTP association you want to add to your provisioning data.

Step 4 If there are no other components that you need to provision, end your provisioning session as described in the "Saving and Activating your Provisioning Changes" section.

Otherwise, proceed to the "Adding DPNSS Signaling Services" section.


Adding DPNSS Signaling Services

To add DPNSS signaling services, perform the following steps:


Step 1 If you do not already have an active provisioning session, start one as described in the "Starting a Provisioning Session" section.

Step 2 Enter the following command to add a DPNSS signaling service:

prov-add:dpnsspath:name="name", desc="description", extnode="mgw", abflag="side", 
sigport=portnum, sigslot=slotnum

The values 255.255.0.0 and 255.255.255.128 are valid. The values 0.0.255.255, 255.0.0.255, and 0.0.0.0 are invalid.

Ensure the destination resolves to a non-zero address.

When the resolved destination address is bit ORed with the netmask value, the result is equal to the netmask (for example, a destination of 10.11.12.13 and a netmask of 255.255.0.0 would be invalid because the ORed result would be 255.255.12.13, which is not equal to 255.255.0.0).

The combination of DESTINATION, NETMASK, and IPADDR must be unique for each IP Route.

The combination of DESTINATION, NETMASK, and PRI must be unique for each IP Route.

When an IP Route is specified in a link object (for example, IPLNK, SESSIONSET, or ASSOCIATION), the IP address resolved from the PEERADDR attribute must be checked against the DESTINATION and NETMASK attributes to verify the IPROUTE is valid.

When an IP Route is specified in a link object (for example, IPLNK, SESSIONSET, or ASSOCIATION), the IPADDR must match the IPADDR of the link.

When an IPROUTE is not specified for a link object (having that option), the IP Address resolved from the PEERADDR attribute must be checked against the defined IPROUTES to verify that it should not be assigned an IPROUTE. If the PEERADDR is on the same subnet as the DESTINATION (based on the NETMASK), and if the IPADDR matches the IPADDR of the link object, then use IPROUTE.

If the NEXTHOP attribute is a hostname or symbolic name from XECfgParm.dat, it can resolve to the address 0.0.0.0, which indicates the IPROUTE is not used. The IPROUTE status shows up in the rtrv-iproute:all command output when in the OOS, OFF_DUTY state.

If the resolved NEXTHOP address is not 0.0.0.0, it must be on the same subnet of the IPADDR.

The commands to retrieve and set the service state of an IP route can be found in the "Retrieving the Service State for IP Routes" section and the "Setting the Service State of an IP Route" section, respectively.

The SCTP association component structure is shown in Table 8.

The following parameters cannot be modified:

NAME

EXTNODE

TYPE

SGP

The following rules apply when creating/editing SCTP associations:

Only one association with a type of IUA can be assigned to an external node

If the type of the association is IUA, the associated external node must have its ISDN signaling type set to IUA, and that external node must be able to support IUA signaling.

If two associations have the same port value, the values of IPADDR1 and IPADDR2 must either be the same or both different.

The values of IPADDR1 and IPADDR2 must be different

If the value of IPPRECEDENCE is not ROUTINE, the value of DSCP must be N/A

If the value of DSCP is not N/A, the value of IPPRECEDENCE must be ROUTINE

The value of MAXRTO must be greater than or equal to the value of MINRTO

When a peer IP address (PEERADDR1 or PEERADDR2) is not on the local subnet of IPADDR1 or IPADDR2, that peer IP address cannot be on the subnet of any other local interface, even if it is not defined within the Cisco MGC software

When a peer IP address (PEERADDR1 or PEERADDR2) is not on the local subnet of IPADDR1 or IPADDR2, an IP route (IPROUTE1 or IPROUTE2, respectively) must be specified

When an IP route is specified, the values set in PEERADDR1 and PEERADDR2 are checked against the DESTINATION and NETMASK values of the IP route(s) to verify that the IP route is valid.

When an IP route is specified, its value for IPADDR must match the related IP address of the association. In other words, IPROUTE1 should have an IPADDR that matches IPADDR1 on the association, and IPROUTE 2 should have an IPADDR that matches IPADDR2 on the association.

When an IP route is not specified, the IP address resolved from the PEERADDR1 or PEERADDR2 parameter is checked against the defined IP routes to verify that it should not be assigned to one of those IP routes. If the peer address is on the same subnet as an IP route, the link should use that IP route.

The value of PEERADDR1 cannot be 0.0.0.0 or 255.255.255.255, and the value of PEERADDR2 cannot be 255.255.255.255

When a hostname is specified for a peer IP address, the hostname must resolve to an IP address.

PEERADDR1 and PEERADDR2 can resolve to the same IP Address. If the external node only has one IP address and two IP addresses (IPADDR1 and IPADDR2) are defined, PEERADDR2 should be set to the same value as PEERADDR1.

Associations, session sets, IP links, SIP links, and SS7 signaling gateway links that share a peer address (that is, PEERADDR, PEERADDR1, or PEERADDR2) must be assigned directly or indirectly to the same external node

When you are deleting an association, and a NASPATH uses the same external node, a warning message is issued to inform the you that the NASPATH must also be deleted. If it hasn't when the provisioning session is copied or deployed, an error message will be generated and the copy or deployment will be stopped.

The value of PORT cannot be set to the same value as the PORT attribute of any IP link, session set, SIP link, or SS7 signaling gateway link

If a value for IPADDR2 or PEERADDR2 is specified, values for IPADDR1 or PEERADDR1 must also be specified. In other words, you cannot have one local address and two remote addresses, or two local addresses and one remote address.

An IP link, session set, SS7 signaling gateway link, or another association with a different external or signaling gateway node cannot use the resolved value set in PEERADDR1 or PEERADDR2.

Only one association can be defined to an SS7 signaling gateway process (SGP)

A value for EXTNODE can be defined only when the association type is IUA

A value for SGP can be defined only when the association type is M3UA or SUA

The maximum number of associations with a type of M3UA is defined in the XECfgParm.dat parameter, M3UA.maxSgp

The maximum number of associations with a type of SUA is defined in the XECfgParm.dat parameter, SUA.maxSgp

The commands to retrieve and set the service state of an association can be found in the "Retrieving the Service State for Associations" section and the "Setting the Service State of an Association" section, respectively.
