5508 WLC failover detection

nicokoerner — Mon, 05 Jul 2021 09:32:47 GMT

Hi all, we run several 5508 in HA mode. Is there a possibility to detect a HA failover through syslog or snmp? I was not able to find any information on the web about syslog messages or snmp OID's regarding cisco's HA failover. The problem we face is simple, from time to time our controllers failover from primary to backup and vice versa. As this is unusuall we would lilke know when this happens and therefore looking for syslog (push) or snmp (pull) information. We run 7.6.120.0 on all boxes and the HA link is connected through a switched (Layer2) backbone connection. We are not looking for any icmp related stuff, in other words, we don't want to ping the redundancy mgmt ip or peer redundancy mgmt ip... Any help or hints are highly appreciated, thanks Nico

You can use 'cLHaPrimaryUnit.0' from the CISCO-LWAPP-HA-MIB, on the primary unit it should always return 'true'.
