I have my vlan defined in my L3 Switch, with ID 20, i am creating my interface in the wlc now.
For VLAN ID, i put 20 (same as in the L3 switch)
For the IP information of the interface, does that need to be an actual IP on the vlan, with the actual mask and gateway or is that one that is put there as just a holder, so it's an address that will never actually appear on the network?
