Just wondering if Cisco has any recommendations around whether to configure the switchport as a trunk or as an access port for Lightweight Access Points?
We've been running some LAPs connected to trunk ports and some connected to access ports and we can't really see any difference.
We're guessing that the trunk port will allow 802.1p values to be carried in the frame, where an access port won't.
Can anyone provide any clarification or recommendations around this for us?
When an AP joins a controller it creates an LWAPP tunnel adjacency (if your are on 5.2 code, it's a CAPWAP tunnel). Like most tunnels, all your traffic is aggregated within the tunnel itself.
So your vlans, qos, ssids, and traffic transverse the LWAPP tunnel, so there is no need to config the access switch with a trunk.
Your aps dont attach to the manager interface, but rather to the AP manager. I forget what code version the ap manager goes away, but you get the point.
