Configuring the SIC Diameter Server Peer (SRC CLI)

 

The SIC Diameter server handles all communication between the SIC and the SRC Diameter server. This procedure describes how to configure the network element in which the SRC Diameter server logically resides, the failover policy, and the Diameter connection between the SIC Diameter server and the SRC Diameter server.

Use the following statements to configure the SIC Diameter peer:

To configure the SIC Diameter server peer:

  1. From configuration mode, access the statement that configures the SIC Diameter server peer and configure the network element where the SRC Diameter server resides. For example, to configure a Diameter network element called diam-ne1 for an SIC group called g1:

  2. (Optional) Specify a description for the network element.

  3. (Optional) Configure the failover policy for the network element. For example, to configure the primary or backup failover policy:

  4. Configure the name of the Diameter peer (SRC Diameter server). For example, to call the peer src-diam-svr1:

  5. (Optional) Specify a description for the Diameter peer.

  6. Specify the IP address of the remote Diameter peer (SRC Diameter server). For example, 10.1.2.3.

  7. Specify the protocol the Diameter peer (SRC Diameter server) uses for Diameter messages (TCP or SCTP).

  8. Specify which port the Diameter peer (SRC Diameter server) receives messages on. For example, port 2222.

  9. (Optional) Specify whether the peer is active or not. If the peer is configured to connect actively, the server periodically attempts to connect (or reconnect after a connection has failed) to the remote peer. If this option is not set, a connection is established only after the remote peer attempts to connect to this server.

  10. (Optional) Specify the priority of the peer for the failover policy. Peers with lower priority values are the preferred routing targets for Diameter requests. Requests are split equally among peers with the same priority level.

  11. (Optional) Specify whether a source IP match is required for the connection. This option determines whether the source IP address of a connection attempt must match one of the configured IP addresses used to connect to this peer. If this option is not set, requests are accepted from any IP address as long as the client presents the correct host name during the capabilities exchange. This functionality allows other peers to exist behind NAS devices.

  12. Specify the origin-host name of the Diameter peer (SRC Diameter server). For example, if the origin-host name of the SRC Diameter server is diam-host1:

  13. (Optional) Specify an ordered set of IP addresses to use for a multilink connection. An IP address of the remote peer is necessary to establish a Diameter connection with the remote peer (SRC Diameter server). For a Diameter connection over TCP, only one configured address is used. Over SCTP, the connection may be established over multiple addresses.

  14. Verify your configuration.
