Feature Overview

To manage licenses, the PGW 2200 provides the license files that are stored in a directory where the PGW 2200 obtains the required license information. PGW 2200 uses the license file to enforce the capacity and features available. Each feature line of the license file is encrypted. Licensing also applies to HSI and BAMS components.

The PGW 2200 requires a unique license file during the execution of the software. This license file allows the software to be loaded and run on a specified set of active/standby servers.

Types of Licenses

This feature enables or tracks the usage of four types of license objects in the PGW based on license files:

Base Software License

Interface License

Configuration-Time Ports License

Run-Time License

Base Software License

The Base Software License allows the PGW application software to execute on a specified Sun platform. The license is assigned to a given PGW system. In a standalone configuration, the license is node-locked to the hostID of the PGW machine. In active-standby configuration, the license is node-locked to the hostID of both PGW machines. The license file controls the maximum number of call-legs that are allowed.

The licensing feature uses different machine identifications for different machine architectures. All Sun Microsystems machines have a unique hostID, which is a 32-bit integer. On Solaris, you can run the command hostid to get the 32-bit hostID in hexadecimal format.

Interface License

The interface license entitles you to use an interface type on a given PGW system. If you configure that interface type without having a license for it, an alarm, "Unlicensed interface configured", appears; calls on that interface are rejected at run time.

. The following interfaces are managed at configuration time:

INAP interface

SS7 interface

PBX interface (including DPNSS interface and QSIG interface)

PRI interface

Legal Intercept interface

The use of SIP, BRI, MGCP, QBE, and EISUP interfaces is unrestricted. Call-leg RTU licenses are enforced on the PGW for SIP and H.323. H.323 is supported on the HSI, which communicates to the PGW through EISUP.

Configuration-Time Ports License

This license specifies how many TDM ports can be configured in a given PGW system. The license file contains a feature ConfigTimeDescrepencyPeriod that allows the discrepancy between the configured TDM ports and the licensed TDM ports for a duration (45 days) from the time the license file is generated. Within this discrepancy period, the configuration-time ports oversubscription is allowed and the H.323 and SIP run time license control is not enforced. After that, the PGW 2200 enforces the configuration time limit at run time. For example, if you configure 10,000 ports but only purchase 8,000 ports license, PGW enforces the license by setting the run-time license number to 8,000. An alarm is always raised in the case of configuration-time ports oversubscription.

All the TDM ports (RTUs) are managed by PGW 2200 licensing using the following two types:

Signaling Mode RTU

Call Control Mode RTU

TDM ports include the following:

Trunking gateway ports (IMT/PRI) usually connected to PSTN

Access gateway ports (DPNSS, QSIG, PRI, BRI) usually connected to a PBX

Run-Time License

The run-time license keeps track of the number of concurrent active TDM ports, SIP call legs, and H.323 call legs. You can exceed the run-time license number by only 30 percent; after that, only emergency calls and priority calls are allowed. An alarm, "Run-time oversubscription", appears if you use more TDM ports, SIP call legs, or H.323 call legs than the number of licenses. For normal call rejections, the alarm "Normal call rejected due to oversubscription" appears. To minimize the impact on performance, every day is divided into 96 15-minute intervals and the alarms are set and cleared at 15-minute intervals.

If the calls counter exceeds 130 percent of the license number in the nth interval, an alarm is set in the (n+1)th interval, and normal calls are rejected if the calls counter exceeds 130 percent of the license number at this interval.

If no call is rejected in the nth interval, the alarm is cleared in the (n+1)th interval.


Note Before the expiration of the ConfigTimeDescrepencyPeriod license feature, no call is rejected. Run-time license control is enforced after the expiration of the ConfigTimeDescrepencyPeriod license feature.


For a TDM call, SIP call, or H.323 call rejected due to license issues, the license reject measurements are increased. SeeTable 1 for these measurements.

Run-time license management is done on the active PGW. If the call is rejected on the originating side, the call is rejected, and corresponding license-rejecting measurement is updated. If the call is rejected on the outgoing side, the PGW performs cause analysis for a possible reroute. For each license check rejection, the license-rejecting measurement is updated.

The counters to entitled licenses are compared to the run-time licenses:

If the incoming or outgoing SigPath is not licensed, the call is rejected.

If both incoming and outgoing SigPaths are licensed, and the counter (or the summation of counters) is within the run-time license limit, the call is permitted.

If you are oversubscribed but still within the oversubscription limit, a corresponding alarm appears in the consequent 15-minute interval. The corresponding counters based on incoming and outgoing Sigpath are increased, and the call is permitted.

If the allowed oversubscription limit is exceeded, the call is rejected if it is a normal call. A corresponding alarm appears in the consequent 15-minute interval. Emergency calls and priority calls are counted but they are not rejected.

Obtaining a PGW License

Users with an Existing PGW Contract


Step 1 Order the PGW application SW upgrade license, consisting of Licensing SW, from the top level in the configuration tool (PGW2200-UPG-TO-9.7).

PGW licensing objects consist of the following:

PGW application SW

DS0 RTU license (signaling and call control)

SIP license

H323 license

SS7 license

PRI license

PBX license

INAP license

LI license

Step 2 Specify the exact number of licenses you purchased or are using for the above license objects. Cisco analyzes the CDR and configuration data and provides the information related to your traffic pattern.

The order is placed on New Product Hold (NPH).

Release of the NPH requires:

PGW product marketing validates the information against the bookings database.

Any discrepancy is resolved by discussion with the account team and/or with you. This might require modification of the order to reflect the eligible number of licenses.

The NPH is removed.

Step 3 A PGW software upgrade CD is shipped to you with a Product Authorization Key (PAK). A PAK is a string of characters identifying the product and the order.

Step 4 Obtain the license file from the Cisco license fulfillment web site using the PAK and the hostID.

Step 5 In the server hostname field, enter the hostname of the server machine where the PGW 2200 software will run.

The hostname is the machine name where the license server will run. If the PGW 2200 software is to run in standalone mode, the license server runs on the same machine as the PGW 2200 software. If the PGW2200 software is to run in active-standby mode, the license server can be on either the primary PGW server machine or the secondary PGW server machine.


Note If you apply several times to obtain a license file for the same PGW, be sure to use the same hostname for each license file application. This can happen if you are expanding RTU licenses. If the hostname is different for different license files, you can use only some of the licenses.



Note In the active-standby mode, to ensure that the hostname is reachable on another PGW, you can either change the DNS server configuration or add this hostname to /etc/hosts.


Step 6 In the server hostID field, enter the hostId of the server machine where the PGW 2200 software will run.

To read the Sun machine host ID, run the Solaris shell command hostid on the machine, an 8-character hexadecimal number is displayed, for example, 83ca7c39.

If the PGW 2200 software is to run in standalone mode, enter the hostID of the server machine. For the hostID field, enter the host ID of the server hardware on which you will install your PGW 2200 software.

If PGW 2200 software is to run in active-standby mode, you need the hostID of both the machines, for example, 83ca7c39 and 83ca7c40. Enter both hostIDs, with a space between them, for example, 83ca7c39 83ca7c40.

Step 7 After you verify the order information, the license file is sent to you in email. We suggest that you keep the attached license file (.lic) in a safe place.

Step 8 You must install the license file in the specified machine before you can start the PGW 2200. See the "Installing the License File" section.


New PGW Contracts


Step 1 Order the PGW application SW upgrade license consisting of a Licensing SW from the top level in the configuration tool (PGW2200-FFX if ordered with hardware or PGW2200-FFX-SWONLY if only software is ordered.)

PGW licensing objects consist of the following:

PGW application SW

DS0 RTU license (signaling and call control)

SIP license

H323 license

SS7 license

PRI license

PBX license

INAP license

LI license

Step 2 The order is placed on New Product Hold (NPH).

Step 3 The order is shipped with a Product Authorization Key (PAK). A PAK is a string of characters identifying the product and the order.

Step 4 Go to the Cisco License Fulfillment web site with the PAK and Host ID of the machine where the PGW 2200 is to be installed and complete the information form.

Step 5 In the server hostname field, enter the hostname of the server machine where the PGW 2200 software will run.

The hostname is the name of the machine where the license server will run. If the PGW 2200 software will be running in standalone mode, the license server will run on the same machine as the PGW 2200 software. If the PGW 2200 software will be running in active-standby mode, the license server can be on either the primary PGW server machine or on the secondary PGW server machine.


Note If you apply several times to obtain a license file for the same PGW, be sure to use the same hostname for each license file application. This can happen if you are expanding RTU licenses. If the hostname is different for different license files, you can use only some of the licenses.



Note In the active-standby mode, to ensure that the hostname is reachable on another PGW, you can either change the DNS server configuration or add this hostname to /etc/hosts.


Step 6 A license file is sent to you in email.

Step 7 You must install the license file on the specified machine before you can start the PGW 2200. See the "Installing the License File" section.


Rehost Licenses

A license file is node-locked to a PGW 2200 pair. This pair might be broken because of a machine crash or other reason. In this case, you must contact Cisco for another license file. This is called license file rehost. Perform the following steps to reinstall the license.


Step 1 When you receive the replacement license file, store it in a safe place.

Step 2 Remove the old license files under /opt/CiscoMGC/license on both the active and the standby machine.

Step 3 Copy the new license files to the PGW 2200 machine under /opt/CiscoMGC/license on both the active and the standby machine.

Step 4 You must install the license file on the specified machine before you can start the PGW 2200. See the "Installing the License File" section.

Supported Platforms

The hardware platforms supported for the Cisco MGC software are described in the Cisco Media Gateway Controller Hardware Installation Guide.

The Cisco MGC Release 9.7(3) software and the license server run on a Sun platform using Solaris 10.

Prerequisites for Using this Feature

The Cisco PGW 2200 must be running Cisco MGC software Release 9.7(3). Prerequisites for this release can be found in the Release Notes for the Cisco Media Gateway Controller Software Release 9.7(3)

Before migrating to the Release 9.7(3) license-based software, check the provisioning on the PGW 2200 to ensure that the extNode type of HSI is correctly provisioned. You can use the prov-ed MML command to fix the provisioning problem.

prov-ed:extnode:name="hsi-name", description="The HSI node connected to PGW",type="H323" 

In PGW Release 9.7(3), if the extNode type of HSI is provisioned as "MGC" instead of "H323", the PGW 2200 rejects the H.323 calls.

HSI Release 4.3 can interoperate with PGW Release 9.7(3) and higher.

For detailed information, see Installing and Configuring Cisco HSI Software at the following url:

http://www.cisco.com/univercd/cc/td/doc/product/access/sc/rel9/hsi_43/43ug/43ch2.htm

Installing the License File

This section contains the steps necessary for installing this feature. If you are installing and configuring the Cisco MGC software on your system for the first time, see the Cisco Media Gateway Controller Software Release 9.7 Installation and Configuration Guide at the following url:

http://www.cisco.com/en/US/docs/voice_ip_comm/pgw/9/installation/software/SW1/97.html


Note You must install the license file on both the active and the standby PGW 2200 for it to function properly.


Install if the PGW 2200 is NOT Running

If the PGW 2200 is not in a running state, perform the following steps.


Step 1 Save the license file (.lic) to a temporary directory on your hard disk

Step 2 Copy the license file to /opt/CiscoMGC/license directory of the PGW.

Step 3 Log in as root.

Step 4 Enter the following command to start the PGW:

/etc/init.d/CiscoMGC start

The license file loads automatically.


Install if the PGW 2200 is Running

If the PGW 2200 is in a running state, perform the following steps.


Step 1 Save the license file (.lic) to a temporary directory on your hard disk.

Step 2 Copy the license file to /opt/CiscoMGC/license directory of the PGW. Licenses are cumulative, so there can be multiple license files of the same type..

Step 3 Log in as mgcusr.

Step 4 Go to the /opt/CiscoMGC/bin directory of the PGW.

Step 5 On the active PGW 2200, run the script reload_lics.sh.

The following is a sample out put from the script:

Deploying Licenses

PGW deploys counted licenses. These counted licenses must apply to both PGWs in an active/standby pair.

HSI and BAMS deploy license files locally. All licenses for these systems are node locked to a particular machine.

Exception Handling

Base License Line Missing in License Files

If the Cisco MGC script stops because there is no valid base license, ensure that you have the valid base license and that you put this license file under /opt/CiscoMGC/license on that machine.

If you have a valid license file but it is in the wrong directory, put the license file in /opt/CiscoMGC/license.

If you have no base license or the license has expired, contact the account team for a formal license.

If you see a "Base license line missing in license files" or "License to expire in a week or less" alarm, see the "New Alarms" section for recommended actions.

If the PGW application software shuts down, see the log file to determine if the shutdown is due to license expiration. If so, contact the account team.

License Server Unreachable

If you see the license server unreachable alarm, you can use the rtrv-lics output to determine how many days license server has been unreachable.

Follow these steps to resolve this problem.


Step 1 Go to the machine where the license server is running (see the first line of the license file for the server hostname).

Step 2 Enter ps -ef |grep lmgrd to see whether the license server daemon is running.

a. If the license server is not running, enter /opt/CiscoMGC/local/reload_lics.sh to restart the license server.

b. If the license server still fails start, check the /opt/CiscoMGC/var/log/flexlm_server.log for detailed information.

c. If the license server is running, but the active Cisco PGW 2200 Softswitch is running on a separate machine, ensure that the Cisco PGW 2200 Softswitch machine can reach the ip address of the license server machine.


Upgrading to Support This Feature

This section contains the steps necessary for upgrading the Cisco MGC software to support this feature. If you are installing and configuring the Cisco MGC software on your system for the first time, see the Cisco Media Gateway Controller Software Release 9 Installation and Configuration Guide.


Note If you are upgrading from a release previous to Release 9.7(3), you have received a license file. If you are upgrading PGW from Release 9.7(3) or a later release, you will receive an upgrade license file.


Perform the following steps to upgrade your Cisco MGC software:


Step 1 Upgrade the standby PGW.

Step 2 Install the license file on the standby PGW.

Go to the Cisco website, use the hostID of the active and standby PGW and PAK (received with the PGW software CD) to apply the license file. Note that the server line will address the host ID of the standby PGW host.

Step 3 Start the standby PGW. Log in as root and enter:

/etc/init.d/CiscoMGC start

Be aware that the license server will start before the start of PGW software.

Step 4 Switch over to the active PGW.

Step 5 Upgrade the previously active PGW.

Step 6 Copy the license file to /opt/CiscoMGC/license on the previously active PGW.

Step 7 Start the PGW software on the previously active PGW.



Note If you cannot start the PGW application, see the "Exception Handling" section.

License Rejecting Reason (Tag: 4244)

Table 2 Reject License Protocol 

Name: License Rejecting Reason

Tag: 4244

Source: MDL

Description/Purpose: Name of reason that caused the call rejection due to license management.

Format: IA5 (string)

Length in Octets: 1-20

Data Value: string

Example: SS7 Interface

ANSI/ITU Variations: None

Extended Data Value: No extended value

General Information: For calls with License Control, a license check must be made. If the license limit threshold is reached or there is no license for this protocol interface, the call is rejected against that license. This record provides the identity of the license that caused the call to fail.

This tag is added to the CDB only if the call admission check results in rejection.

MGC Release: Release 9.7.3 and later.

License Rejecting Direction (Tag: 4245)

Table 3 License Rejecting Direction 

Name: License Rejecting Direction

Tag: 4245

Source: MDL

Description/Purpose: Indication of whether the call was rejected by a license relating to the PGW originating (incoming) or terminating (outgoing) side.

Format: IA5 (string)

Length in Octets: 1-20

Data Value:

1 = Inbound (PGW originating side)

2 = Outbound (PGW terminating side)

ANSI/ITU Variations: None

Extended Data Value: No extended value

General Information:

For calls with License Control, a license check must be made. If the license limit threshold is reached or there is no license for this protocol interface, the Call is rejected against that license. This record provides an indication of whether this was rejected by the originating (inbound) or terminating (outbound) side.

This tag is added to the CDB only if the call admission check results in rejection.

Processes

The LMAgent process was added for this feature. For information on other processes for the Cisco MGC software, see the Cisco Media Gateway Controller Software Release 9 Operations, Maintenance, and Troubleshooting Guide.

Table 4 shows the LMAgent process added for this feature.

Table 4 New Processes Controlled by the Process Manager 

Process
Description

LMAgent

License agent. Handles all the business about licensing based on license client library. Communicates with other processes through IPC.


Cause and Location Codes

Two internal cause codes described in Table 5 were added for this feature:

IC_CALL_LICENSE_REJ

IC_RUNTIMR_LICS_REJ

For information on other cause and location codes for the Cisco MGC software, see the Cisco Media Gateway Controller Software Release 9 Dial Plan Guide.

Table 5 Internally Generated Cause Codes 

Internal Cause Code
Cause Code Explanation

IC_CALL_LICENSE_REJ

To allow identifications of call rejections due to license control and also to allow individual cause analysis of such events, a new cause value IC_CALL_LICENSE_REJ is added to the Call context CauseEnum.

IC_CALL_LICENSE_REJ—Internal value 174. If the cause analysis result is to release the call, set the internal cause code to IC_CALL_REJECTED. This cause code is mapped to the corresponding protocol cause code, for example, "403 Forbidden" for SIP protocol.

IC_RUNTIMR_LICS_REJ

When an initial run-time license checking request is made and the call is rejected, the next action taken by the universal call module (UCM) is to invoke cause analysis on the new internal cause.

The run-time license checking is added to the UCM module. In the case of a call rejected due to run-time license management, cause analysis is invoked. PGW also invokes the update of run-time license management call rejection measurement and collection of the call detail record (CDR).
