Hello,
I have a Cisco Wireless Lan Controller connected to gig 1 and from the WLC I'm unable to ping vlan4, I can ping every other vlan except for this one. Do I just need to add vlan 4 to the port channel1?
Any help would be great and I can provide any additional info.

If the WLC is sending multiple vlan traffic across the trunk then yes, unless you add vlan 4 to the trunk then the WLC will not be able to contact devices in vlan 4.

Thanks Jon,
So I would just add it under the Portchannel1 instead of gig1...correct?
Wireless is working fine to the multiple ssid vlans.
We run ip phones and just picked up a couple 3631 wireless ip handsets and am trying to get them to communicate to vlan4 which our callserver and ethernet phones are on.
Thanks!

You should add the vlan to the Port-channel and it should replicate to all interfaces within the channel.

Add it to both.
Out of interest why run a port-channel with only one interface gi0/1 in it ?
Also - can you post output of "sh int trunk gi0/1" from your switch ?

Thanks guy's.
Our prior admin set this switch up so not sure as I only know some basic configuration at this point.
Also Jon, when I run that command I get;
AELIB_SW178#sh int trunk gi0/1
^
% Invalid input detected at '^' marker.
Thanks,
Shane
