Support of Provisionable QoS for Signaling Traffic
Document Release History
Feature History
9.7(3)
The Support of Provisionable QoS for Signaling Traffic feature was introduced on the Cisco MGC software.
This document describes the PGW support for the optional provisioning of QoS/TOS value for all signaling traffic feature.
This feature is described in the following sections:
•
Supported Standards, MIBs, and RFCs
•
•
Feature Overview
This feature provides support of provisionable QoS over all signaling links as well as intra-PGW and EGW traffic.
This feature adds provisionable QoS support with the default value set to DSCP CS3 in accordance with Cisco baseline QoS recommendations for the following:
•
–
–
–
–
–
–
–
–
–
–
•
Benefits
This feature will allow you to set appropriate priority for various signaling traffic to be transported between PGW and Cisco EGW and other call control entities, like Cisco CallManager, Cisco Unity, SIP servers and Gatekeepers and Gateways over QoS-enabled IP networks.
Cisco EGW already supports fixed QoS in clustering over the WAN implemented by IPtables packages. Now the QoS will be supported by MGC itself to support dynamically provisionable QoS for both PGW and Cisco EGW.
Restrictions
The QoS feature is supported for use by MGC itself. TimesTen would continue to use IPtables packages to get QoS support.

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) at:
http://www.cisco.com/univercd/cc/td/doc/product/access/sc/rel9/relnote/rn973.htm.
Provisioning This Feature
You must start a provisioning session to enable this feature. See the Cisco MGCP Provisioning Guide for details on how to start a provisioning session. Provision the transport path between the IUA IOCCs of the Cisco PGW 2200 and the external Cisco media gateway nodes. Communication between the Cisco PGW 2200 and the Cisco media gateways is provisioned so that there is a reliable communication path between the two platforms.
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.

For more detailed information about provisioning your Cisco MGC, 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:
•
–
–
Note
•
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 provision this feature. For more information on provisioning other components on your Cisco MGC, 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
The prov-cpy MML command is used to save and activate your changes on simplex Cisco MGC (single host) systems.
Note
Caution
The prov-dply MML command is used to save and activate your changes on the active and standby
Cisco MGCs in a continuous-service system. This command should not be used on a Cisco MGC in a simplex configuration.
Note
Ending a Provisioning Session Without Activating your Changes
If you want to end a provisioning session without saving and activating the changes you have entered, 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 you can use this command to retrieve provisioning data are described in the following sections:
•
•
•
•
•
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_nameWhere:
•
•
For example, to view the provisioning data for a SS7 signaling service called ss7svc1, you would enter the following command:
prov-rtrv:ss7path:name="ss7svc1"The response to the command is dependent upon the component type associated with the desired component. For example, to view the properties for an SUA routing key called suakey1, you would enter the following command:
prov-rtrv:suakey:name="suakey1"Retrieving Data for All Components
You can retrieve data on all of 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:allRetrieving 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.
For example, to view the provisioning data for all SS7 signaling services, you would enter the following command:
prov-rtrv:ss7path:"all"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:sessionThe system returns a response similar to the following:
MGC-02 - Media Gateway Controller 2003-01-13 13:39:19M RTRV"session=jtest:session"/*Session ID = mml1SRCVER = activeDSTVER = 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:variantsCommand Reference
This section documents new, modified, or deleted Man-Machine Language (MML) commands. All other MML commands are documented in the Cisco Media Gateway Controller Software Release 9 MML Command Reference Guide.
New MML Commands
This section contains the MML commands that are new for this feature.
PROV-ADD:tos:dscp—Add TOS Value
PROV-DLT:tos—Delete TOS Value
PROV-ED:tos:dscp—Edit TOS Value
PROV-RTRV:tos—Retrieve TOS Value
