Hi,
Im trying to create port channel between switch and WLC, port channel is up but 2nd link WLC and switch is not coming up.
Cable is fine and I can see link flaps error on WLC logs.
Any idea..

Hi ,
Do you use pagp port-channel ? if yes please try to use mode on in your port channel.
WLC probably does not support pagp.
Best...

Hi,
We are using "on" mode, from switch side port channel is up with 1st link but 2nd link status is showing not connect.
When I check WLC, I can see 2nd link flaps error.We have also verified the cable connectivity
Am I missing anything.

Use Lacp because pagp isn't supported by most of WLC.
Check your cabling too.

Hi Farrukh,
We are not using PAGP, 2nd switchport is configured with On mode and cabling also verified.
1st link is working fine and channel is up but 2nd link is showing "not connect" and WLC is showing link flaps error which is confusing us

Use LACP port-channel and verify the console log from switch side.
