Configuring Diameter Peers

You can configure the remote peers to which Diameter sends messages. Port 3868 is used for active connections to peers by default.

To configure a remote peer for a Diameter instance:

  1. Specify the name of the Diameter peer.
  2. Specify the address of the Diameter peer.
  3. Specify the transport that Diameter uses for active connections to the peer.
  4. (Optional) Specify the port that Diameter uses for active connections to the peer. The default is port 3868.
  5. (Optional) Specify the time to wait for connection acknowledgment from the peer. The default is 10 seconds.
  6. (Optional) Specify the time to wait before trying to reconnect to a peer after receiving a Disconnect-Peer-Request message with the DO_NOT_WANT_TO_TALK_TO_YOU value for the Disconnect-Cause AVP. If you do not set a value, no reconnection attempt is made.
  7. (Optional) Specify the time to wait for a Capabilities-Exchange-Answer message from the peer. The default is 10 seconds.
  8. (Optional) Specify the time to wait between connection attempts for this peer. The default is 30 seconds.
  9. (Optional) Specify the time to wait for a Device-Watchdog-Answer message from the peer. The default is 30 seconds.
  10. (Optional) Specify the time to wait in the Closing state while disconnecting this peer. The default is 10 seconds.
  11. (Optional) Specify the size of the incoming queue for the peer. The default is 6000. You can specify a smaller value if you want to throttle the peer.
  12. (Optional) Specify the size of the outgoing queue for the peer. The default is 6000. You can specify a smaller value if you want to throttle the peer.
  13. (Optional) Specify the high watermark of the outgoing queue for the peer.

    The default is 80 percent. If the queue size reaches the high watermark, the peer is marked unavailable, any new messages to the Diameter network element are not sent to this peer, and the SNMP trap Diameter_PeerOutQHiWMarkNotif is generated.

  14. (Optional) Specify the low watermark of the outgoing queue for the peer.

    The default is 60 percent. If the queue size descends to the low watermark after reaching the high watermark, the peer becomes available and the SNMP trap Diameter_PeerLowQHiWMarkNotif is generated.
