I recently moved a 4402 Wireless LAN Controller off of a 6509 connection and onto a Nexus 2k connection. The config on the 6509 for the WLC was as follows:
interface GigabitEthernet2/2/32
description ESC-WLC-1 Wireless LAN Controller
switchport
switchport trunk encapsulation dot1q
switchport mode trunk
mls qos trust cos
spanning-tree portfast edge trunk
When I configured the 2k FEX for connectivity, I entered the following comparable config:
int e101/1/23
description ESC-WLC-1 Wireless LAN Controller
switchport mode trunk
spanning-tree port type edge trunk
I was not able to get connectivity to the WLC. The WLC was set to trunk and the interface was up, but even when I issued a show vpc consistency parameters on that interface and all looked good, no connectivity.
Here are some of my log captures:
2011 Nov 11 07:39:24 ESC-NX5010-1 %ETHPORT-3-IF_ERROR_VLANS_SUSPENDED: VLANs 1-5,10,51,100-112,120,155,201-202,251-252,255,302,307,310,320,1109 on Interface Ethernet101/1/23 are being suspended. (Reason: Co

Does anyone know if there is anything special on the Wireless LAN Controller that needs to be configured?
Thank you,

Are you using VPC among the upstream Nexus 5k's which control your 2k FEXs? If so, you need to have the configs synced among your VPC members.
Just a thought - hope this helps.

Yes, they are synced up.
