Hello all,
Goal: Setting up a new multifloor building and the goal is to have total ability to roam between floors without dropping connections using the follwing:
5508 controllers
1142 LAP's
Layer 3 connected network EIGRP between floors
No layer 2 trunking between distribution switches for better failover
See attached diagram
Vlan 200 is /22 network for Wireless Client
Configuration of switchport with controller:
interface GigabitEthernet4/46
description nwc01-1211-01b
switchport
switchport trunk native vlan 210
switchport trunk allowed vlan 200,208,210
switchport mode trunk

wrr-queue queue-limit 75 15
wrr-queue random-detect min-threshold 2 70 100
wrr-queue random-detect max-threshold 2 90 100

wrr-queue cos-map 2 1 1 2 3 4

end
Basically since we are not doing DOT1Q trunking between the core switches I cannot place my Access Points in vlan 200 per floor. I can them an IP using the access VLAN but I want to distribute IP's address to the clients from the WLC.
The thought process is because the LAP creates an LWAPP tunnel back to the controller then I should be able to centrally distribute IP addresses from the 200 vlan.
I apologize for the confusion but I have a hard time explaining this through the forum.
Solved! Go to Solution.

Jake,
The AP does not need to be in VLAN 200, they can belong to any VLAN so long as it can route to the wlc's mgmt interface, tehy will join. ALl client traffic is tunneled back to the WLC for ingress/egress. So if you want your clients to be in VLAN 200, it will work, so long as the WLC has L2 access to that VLAN.

Yes this was the answer. The concept I was missing in all of the WLC configurations was Dynamic interfaces attached as you said to a L2 vlan. The switch port then has the trunks for those accepted vlans.
Thank you,

Jake,
Make sure you have a layer 2 adjacency between your distros where your WLCs live for your wireless VLANs. Trunk between the two for better fail over.
