Clustered Mediation Servers
For reliability, paired Mediation servers can fail over when they transmit SNMP traps and/or Network Element-initiated Syslog Messaging to Application Server(s). For failover to work, you must enable multicast between the cluster’s mediation servers.
Each server in the cluster has a primary and a secondary role, and uses keep-alives heartbeats to verify the other Mediation server's operational state. Based on the operational state, only one Mediation server (the primary) forwards messages to the Application Server(s) for processing.
You must configure Network Elements to send SNMP traps and/or Syslog messages to all servers.
See Mediation Clustering for more specifics.
