Devices FAQs and Troubleshooting
Symptom SNMP Unreachable faults are displayed more frequently than the set polling interval.
Possible Cause When the WLSE polls for any faults, it also checks if the device is SNMP reachable.
If the device is unreachable, it will generate an SNMP Unreachable fault no matter what the SNMP
Reachable poll interval is.
Recommended Action None.

Q.
Can the WLSE auto rename new APs to a unique name - for example incrementally in the form of
ap01, ap02 and so on?
A.
Auto assigning incremental names to APs is not possible, but a workaround could be to select
Devices > Discover > Discover > Advanced Options, and use the Name Format field. Click Learn
About Name Format to understand the various options.
Q.
Why is hostname (device name), sysContact, and sysLocation information not updated in the WLSE
after I change these parameters on the access points?
A.
The hostname (device name), sysContact, and sysLocation parameters are updated during discovery,
not during inventory. You should rediscover the devices (without deleting them), after making the
changes on the access points.
