Problem Description: Cisco WLC showing UNKNOWN status

This happened while using the following certification:
# Cisco 5760 Wireless Controller 
.1.3.6.1.4.1.9.1.1645 {
     TYPE = WirelessController
     VENDOR = Cisco
     MODEL = AIR-CT5760-HA-K9
     CERTIFICATION = TEMPLATE
     CONT = Cisco-IOS-Switch
     WIFI = Cisco-Wireless
     NEIGHBOR = Cisco-Cdp
     HEALTH = Cisco-WLAN-4402
     BRIDGE = Cisco
     VLAN = Dot1q

 INSTRUMENTATION:
    Environment                         = CiscoWLAN4402
    CPU/Memory                          = CiscoWLAN4402
    Interface-Fault                     = MIB2
    Interface-Performance               = CiscoRouter
    Interface-Ethernet-Performance      = CiscoRouter_Ethernet
    Port-Fault                          = MIB2
    Port-Performance                    = MIB2
    Port-Ethernet-Performance           = dot3_Ethernet
    WirelessAccessPoint-Fault           = Cisco_AireSpace_Wireless_MIB
    WirelessClient-Fault                = Cisco_Lwapp
    WirelessController-Performance      = Cisco_Airespace_Switching
    AuthenticationServer-Fault         = Cisco_Airespace_Wireless_MIB
}

Environment

VMware Smart Assurance - SMARTS

Cause

Troubleshooting: 

1: VLAN 987 is discovered:
dmctl -s pdcd06-ic2-ampm1 get UnitaryComputerSystem::cnepif-gedos04-12830195e004.d06.mso.mci.com::ComposedOf
{ Interface::IF-cnepif-gedos04-12830195e004.d06.mso.mci.com/13 

2: It  responds to SNMP:
v880259@pdcd06-ic2 { ~ }-> snmpwalk -v2c -c XXX 192.168.203.232 ifDescr.13
IF-MIB::ifDescr.13 = STRING: Vlan987
v880259@pdcd06-ic2 { ~ }-> snmpwalk -v2c -c XXX 192.168.203.232 ifOperStatus.13
IF-MIB::ifOperStatus.13 = INTEGER: up(1)
v880259@pdcd06-ic2 { ~ }-> snmpwalk -v2c -c XXX 192.168.203.232 ifAdminStatus.13
IF-MIB::ifAdminStatus.13 = INTEGER: up(1) 

Smptom: It is  shown unknown in SMARTS:
v880259@pdcd06-ic2 { ~ }-> dmctl -s pdcd06-ic2-ampm1 get Interface::IF-cnepif-gedos04-12830195e004.d06.mso.mci.com/13::AdminStatus
UNKNOWN
v880259@pdcd06-ic2 { ~ }-> dmctl -s pdcd06-ic2-ampm1 get Interface::IF-cnepif-gedos04-12830195e004.d06.mso.mci.com/13::OperStatus
UNKNOWN

Resolution

Following these steps, resolved this 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.
After making all the changes and triggering a  reconfigure, the Interface got the instrumentation back and the status got populated.
