New IPSG Features
This section identifies new IPSG features available in release 15.0.
Lawful Intercept Support for IPSG
The Lawful Intercept feature is now supported on IPSG. For more information, contact your Cisco representative.
Support for Peer Selection at Diabase
In the earlier Gx implementation, Diameter Policy Control Application has the limitation to mandatorily configure hosts
as part of IMS Authorization service or associate a host template and select the hosts to be communicated for each
subscriber session. Since the peer selection can occur at diabase, and the application need not select any hosts, this
feature is introduced to remove the restrictions imposed in the application and allow diabase to pick the peers in a
round-robin fashion. In addition, this feature addresses peer selection at diabase even when the hosts picked by
application are not active. This change in behavior is controlled through the CLI command
as part of IMS Authorization service or associate a host template and select the hosts to be communicated for each
subscriber session. Since the peer selection can occur at diabase, and the application need not select any hosts, this
feature is introduced to remove the restrictions imposed in the application and allow diabase to pick the peers in a
round-robin fashion. In addition, this feature addresses peer selection at diabase even when the hosts picked by
application are not active. This change in behavior is controlled through the CLI command
endpoint-peer-select
as the default behavior is to drop the call if the server discovery fails at application.
When the peers are selected from endpoint, the output of CLI command
