This article suggests the steps to be followed when Cisco WLC show UNKNOWN status on Managed Interfaces
Smarts 10.1.X
dmctl -s <AMPM Domain> get UnitaryComputerSystem::device::ComposedOf
{ Interface::IF-device/13 }
# snmpwalk -v2c -c XXX #.#.#.# ifDescr.13
IF-MIB::ifDescr.13 = STRING: Vlan987
# snmpwalk -v2c -c XXX
#.#.#.#
ifOperStatus.13IF-MIB::ifOperStatus.13 = INTEGER: up(1)
# snmpwalk -v2c -c XXX
#.#.#.#
ifAdminStatus.13IF-MIB::ifAdminStatus.13 = INTEGER: up(1)
# dmctl -s
<AMPM Domain>
get Interface::IF-device/13::AdminStatusUNKNOWN
# dmctl -s
<AMPM Domain>
get Interface::IF-device/13::OperStatusUNKNOWN
Please evaluate the following steps to resolve the issue:
1. The polling group on "WirelessController" did not have the right settings applied (i.e Wireless_Connectivity_Polling_Setting).
2. Secondly, under the threshold group, the Interface group did not have the right settings applied (i.e. Interface port performance).
3. The interface on the 1Gig threshold groups did not have this interface and added them too.
4. After making all the changes and triggering a reconfigure, the Interface should now have the instrumentation back and the status would be pop
