We have a Cisco WCS running version 220.127.116.11 and WLCs running version 4-2-207-0.
The WCS can see and reach all the controllers but when trying to apply a specific WLAN template the following message comes up on one of the controllers. All other controllers have the WLAN template applied successfully.
SNMP operation to Device failed: Failed to create WLAN on device. Please try applying again.
Not to confuse this with another caveat the template does fail to apply to the WLC.
This “suspect” controller accepts all other templates such as RADIUS, NTP and SNMP successfully
What is the exact version of WCS ?
What is the exact version of WLC ?
Have you tried to delete the template and re-create a new one and push out the changes?
Here is the release notes for WCS:
Download and install the latest version of WCS 6.0.170 and let me know if you are still having issues.
1. If you can't upgrade, get me the WCS logs after enabling trace from Administration ---> Logging ---> Logging Level ---> Trace. Keep everything checked except snmp mediation.
2. Duplicate the problem .
