Faults FAQs and Troubleshooting

Symptom After adding an AAA server to a WLSE, the fault ‘AAA server is Not available’ is generated for that AAA server.

Possible Cause There are several reasons for this error messages: the wrong secret (a secret that does not match what is configured on the AAA server) was entered; the WLSE IP address is not configured as a NAS on the server, or the server is unreachable.

Recommended Action Enter the correct secret; the one that is configured on the AAA server or configure the WLSE IP address as NAS on the server.

Symptom A polling interval for a fault is increased from one minute to a higher value, yet the fault reappears after one minute, not in new time set for the polling.

Possible Cause The new polling time did not register.

Recommended Action Disable fault polling on the relevant policy or threshold, then manually clear the fault. Change the fault polling interval on the policy or threshold to the new setting, then enable fault polling on the relevant policy or threshold.

Symptom The Display Fault view is blank.

Possible Cause There are no faults to report based on the filtering criteria you entered.

Recommended Action Not applicable.

Symptom Email fails to arrive at its destination.

Recommended Action Configure the WEP keys for the corresponding VLAN.

Symptom No email notifications are being received for low priority faults.

Possible Cause No email notification is sent for lower priority faults if higher priority faults already exists for that fault
