Feature Description

PCF supports diameter peer load rebalancing.

How it Works

This section describes how this feature works.

  • CLI is implemented to show the diameter peer connections and its mapping to the individual pods.

  • CLI is also used to initiate disconnection of a peer identified by its peer fqdn and realm details. The peer disconnect request is redirected to the respective diameter stack where the connection termination is managed in graceful manner.

Feature Configuration

To configure this feature, use the following configurations:

  • View the diameter peer connections per pod.

  • Diameter peer disconnection.

View the Diameter Peer Connections Per Pod

This section describes how to view the diameter peer connections per pod.

To view the diameter peer connections per pod, use the following configuration in the Policy Ops Center console:

show diameter peer-status 

The output of this command displays the peer hostname, peer realm, pod IP and the status.

The following is a sample output of the show diameter peer-status command.

pcf# show diameter peer-status 
PEER HOSTNAME         PEER REALM              POD IP          STATUS                                                                
----------------------------------------------------------------------- 
site-host-rx1   site-rx-client-cisco.com   192.168.174.137   Connected 
site-host-rx2   site-rx-client-cisco.com   192.168.174.137   Connected 

Diameter Peer Disconnection

This section describes how to disconnect the diameter peer connection.

To disconnect the diameter peer connection, use the following configuration in the Policy Ops Center console:

diameter-peer disconnect fqdn <peer-fqdn> realm <peer-realm> 

The following is a sample connection success output of the diameter-peer disconnect fqdn site-host-rx1 realm site-rx-client-cisco.com command.

pcf# diameter-peer disconnect fqdn site-host-rx1 realm site-rx-client-cisco.com 

The following is a sample connection failure output of the diameter-peer disconnect fqdn site-host-rx1 realm site-rx-client-tmo.com command.

pcf# diameter-peer disconnect fqdn ecscf-client-s111 realm cscf.mnc010.mcc100.3gppnetwork.org
