Cisco Wireless Controller Configuration Question

Hi Expert
Here is a question on wireless controller configuration. I read a papers on the WLC configuration. Please see the attached paper. The question is in yellow highlighted lines. The switch interface f0/9 is connected with LAP, but the configuration for the interface is like this

interface f0/9
Description Connected to the LAP
Switchport access vlan 60
switchport mode access
no ip address

My question is since vlan 10 and 20 is for PC, why does it use "switch access vlan 60" instead of "switchport access vlan 10 or 20" ? how do vlan 10 and 20 go from AP to the router or vice versa in present case ?
Thank you.

HI
VLAN 10 GUEST vlan
VLAN 20 is internal VLAN
VLAN 60 is associated with VLAN 10 AND VLAN 20 and active trunk port.

The port where an AP connects is configured as an access port (only in a single VLAN) when dealing with Cisco WLCs.  You don't generally use a trunk port for a Lightweight AP as all traffic is what's known as 'centrally switched'.

This means that the user traffic between the AP and WLC is encapsulated in a LWAPP or CAPWAP tunnel and is placed on the correct VLAN at the switchport where the WLC connects.  From there the traffic is treated as normal wired traffic until it gets to the destination.

There are times where you'd want to connect the AP to a trunk port, but that's probably for a different scenario and I wouldn't get too worried about this if you're unfamiliar with WLCs.

So, as per the doc, the Guest VLAN is 10, the internal VLAN is 20 and the management VLAN is 60.  I suspect that the AP is on the same VLAN as the WLC in your example to keep it simple.
