I have cisco PI 2.0 and WLC wism2 with IOS 7.4.121
i added the WLC to the PI and i found the WLC detected as "unknown" under "device type" in cisco PI
please advice what is the issue may be ?
Most commonly, this is caused by incorrect matched SNMP communities or versions or ssh/telnet login credentials.
thanks for your support
I already changed the SNMP community more than one time and rechecked on the username used for the SSH login and they are correct and the problem is still existing.
I would have to agree with Martin.
Delete it and try again.
Configure > controllers > Add controllers
Add your community string and SSH username and password
When it remains in the unknown category it generally means you are missing SNMP or SSH credits. Make sure you can ping the controller from prime as well.
