Possible Cause At each instance of synchronization and failover, the standby AAA RADIUS server goes down, thereby triggering the “HA standby AAA radius server not available” fault during each instance.

Recommended Action

a.Select Faults > Manage Fault Settings.

b.Select the AAA Server settings in the relevant fault profile.

c.Set the consecutive polling cycle count to 2 for the “Radius Server Not Available” fault. Result: This fault may reoccur, but only rarely.

Symptom The error message “AAA server not available” is falsely displayed for the following built-in AAA server types: LEAP server, RADIUS server, PEAP server (applies to WLSE Express only).

Possible Cause The IP domain name has not been configured on the WLSE.

Recommended Action Enter the CLI command ip domain-namedomain (where domain is your domain name; for example cisco.com). Then reload the WLSE.

Symptom In a redundant cluster, faults cannot be created or cleared, and there may be other symptoms. The daemons.log file contains the following messages, which indicate a virtual machine crash.
