I am having an issue with deploying 2504 WLC for multiple SSIDs with different VLANS. I cant seem to make the access points to join the controller on a trunk port. they only work when the WLC is connected to an access port. Anyone encounter this or has a solution? Thank you in advance
the native vlan on the switchport is the vlan for "untagged packets"
th make the controller and switch match:
1) in the controller you can specify vlan "0" for the management interface
this results in untagged packets to send to the switchport
so set the switchport to access or set the native vlan to make a match.
2) alternatively set the switchport to trunk
and set the management vlan id in the controller to the desired vlan id (something other than "0").
if the management vlan is on a different subnet than the AP, you can help the AP to discover the controller by using DNS entry or DHCP option.
if you use multiple controller ports to the same switch, this also needs some extra attention.
