I can't get the WLC to form a LAG, the 5508 has 2 SFPs direct to Nexus 7k. Enabled LAG and rebooted. The 5508s port 2 just stays Link Down in WLC.
!int port-channel 31vpc 31
switchport mode trunk
channel-group 31 mode active
show run int eth1/12
Ethernet1/12 is up
Belongs to Po31
int port-channel 31vpc 31
show run int eth1/7
Ethernet 1/7 is down (Link not connected)
You can't use mode active. The WLC does not negotiate, you have to use mode on.

Changed to channel-group 31 mode on (which is also the default, so you can type channel-group 31 as well)
However I still get 1 port up, 1 port down.
Try swapping g the ports. Could be a bad cable or SFP

In the 5508 is the SFP hot-swappable ? or do I need to power down the 5508 to swap SFPs?
You can hot swap them
Just out of curiosity, I can see from the configuration that you are connected to 2 different Nexus. Are you using a Virtual Port-Channel concept here
Thank you! (Mode On) worked for me!
Controller cannot establish SXP connection with a Cisco Nexus 7000 Series switch.
Symptom: An SXP connection from the controller to the Cisco Nexus 7000 Series switch reports the On state on the controller side while the switch reports the Waiting for Response state.
Conditions: Establishing SXP connection between the controller and ASA.
Workaround: Add an intermediate device that supports SXPv2 between the controller and the Cisco Nexus 7000 Series switch.
