WCS --> WLC "Device un reachable"

[yprasannas]

Added WLC to WCS. Rebooted WLC from WLC and WCS cant reach WLC eventhough I can ping and access WLC. Verified SNMP and looks fine. Happened on two WLC's. I am waiting for almost 2 hours for WCS to talk WLC...

Please update the following informations

'show run-config' from the WLC and 'show run' from Switch connected to WLC while specifying the ports of Switch that connect to WLC in 2 separate text files.

=> Show msglog after the problem happens.

=> Check if there is crashes file available (WLC GUI ->Management ->Controller Crash)

=> 'show port summary' from the WLC when such problem happens.

=> 'show ip int br' from Switch connected to the WLC when such problem happens.

=> 'show arp switch' form WLC when such problem happens.

=> 'show arp' from Switch when such problem happens
