IPSG Feature Changes as of May 31, 2013

This section provides information on IPSG feature changes in release 14.0.

IMPORTANT:

For more information regarding features in this section, refer to the IPSG Administration Guide for this release.

New IPSG Features

This section identifies new IPSG features available in release 14.0.

Accounting Stop Response in Packet of Disconnect (PoD) Event

IPSG does not respond to RADIUS Accounting stop messages after a PoD is sent to GGSN, as the subscriber at IPSG is cleared soon after the PoD is sent. With this release, IPSG waits for the accounting stop request after sending the PoD to the client for a configurable time.

Modified IPSG Features

This section identifies IPSG features modified in release 14.0.

IPSG Support on ASR 5500 Platform

With this release, the ASR 5500 platform supports IPSG RADIUS Server configuration.

Previous Behavior: IPSG was supported on the ASR 5000 platform only.

New Behavior: The ASR 5500 platform now supports IPSG RADIUS Server configuration.

IPSG Command Changes as of May 31, 2013

This section provides information on IPSG command changes in release 14.0.

IMPORTANT:

For more information regarding commands in this section, refer to the Command Line Interface Reference for this release.

New IPSG Commands

This section identifies new IPSG commands available in release 14.0.

None for this release.

Modified IPSG Commands

This section identifies IPSG commands modified in release 14.0.

radius accounting

This command in the IPSG RADIUS Server Configuration Mode allows you to specify the IP address and shared secret of the RADIUS accounting client from which RADIUS accounting requests are received. The RADIUS client can be either the access gateway or the RADIUS accounting server depending on which device is sending accounting requests.

The act-onoff keyword specifies send accounting On/Off messages to AAA Server. Previously, this option was applicable only to the IPSG Proxy Mode. With this release, this option is applicable to both IPSG Proxy and Server Modes.

    configure

       context context_name

          ipsg-service
    <service_name> mode radius-server

             radius
    accounting client { <ipv4/ipv6_address> | <ipv4/ipv6_address/mask> } [ encrypted ] key
    <key> acct-onoff [ aaa-context <aaa_context_name> ] [ aaa-group
    <aaa_server_group_name> ] [ clear-sessions ] + ]

          end

The IPSG Server mode does not send any messages to the AAA server. Instead, it will clear the session, and send the response back.

radius accounting

This command in the IPSG RADIUS Server Configuration Mode allows you to specify the IP address and shared secret of the RADIUS accounting client from which RADIUS accounting requests are received. The RADIUS client can be either the access gateway or the RADIUS accounting server depending on which device is sending accounting requests.

The release-on-acct-stop acct_stop_wait_timeout command specifies to wait for the accounting stop request after sending the Packet of Disconnect (PoD) to the client for the specified time. This indicates the time to wait to clear the call in case IPSG does not receive any accounting stop for the subscriber after sending the PoD.

    configure

       context context_name

          ipsg-service
    <service_name> mode radius-server

             radius
    accounting client { <ipv4/ipv6_address> | <ipv4/ipv6_address/mask> } [ encrypted ] key
    <key> disconnect-message release-on-acct-stop <acct_stop_wait_timeout>

          end

Note: This keyword is configured on a per RADIUS accounting client basis and not for the entire service.

Virtual APN Support

IPSG Virtual APN configuration is supported in this release. This feature allows the carriers to use a single APN to configure differentiated services. The APN selection is based on the APN supplied to the IPSG in conjunction with the following configurable parameters:

- access-gw-address (for IPSG this means the RADIUS client)
- msisdn-range
- rat-type

For more information, refer to the virtual-apn CLI command in the APN Configuration Mode Commands chapter of the Command Line Interface Reference.

Modified IPSG Features

This section identifies IPSG features modified in release 14.0. There are two kinds of modified features: enhancements and behavior changes. Enhancements are feature changes based on customer change requests. Behavior changes are feature changes that modify an existing behavior and may result from software error corrections (bug fixes).

None for this release.

virtual-apn

In support of the IPSG Virtual APN feature this command, previously available to other gateways, is now available to the IPSG. This command configures references to alternative APNs to be used for PDP context processing based on properties of the context. This command also configures the APN properties against which the PDP contexts are compared.

Note that in this release IPSG Virtual APN configuration supports only the following parameters:

- access-gw-address (for IPSG this means the RADIUS client)
- msisdn-range
- rat-type

For more information, refer to the virtual-apn CLI command in the APN Configuration Mode Commands chapter of the Command Line Interface Reference.

APN Configuration Mode

    virtual-apn preference priority apn apn_name [ access-gw-address { ip_address | ip_address/mask } | [ msisdn-range { from msisdn_start_range to msisdn_end_range } ] [ rat-type { eutran | gan | geran | hspa | utran | wlan } ] ]
