2   Procedure

This section describes the procedure to follow when this alarm is received.

2.1   Analyzing Alarm

Diameter connections are normally re-established automatically without user intervention. If the node is configured as a connection initiator, the node tries to establish the connection periodically. If the node is configured as a connection acceptor, the node waits for new connection requests from the peer node. Timers are available to control the reestablishment of connections automatically. For more information, refer to attribute tcTimer.

If the Diameter connection is not re-established automatically within a certain time (normally 120 seconds), select action according to alarm attribute Additional Text, as follows:

2.2   Actions for Format Error of CER/CEA Messages

Do the following:

  1. Wait for automatic reconnection.
