Can anyone tell me how I can deploy Cisco 1230 Access points on the same subnet in a Cisco network that has different vlans in each closet? I realize that I can trunk a single VLAN to each closet switch (where my access points are connected) , but I have redundant trunks to each clost switch and by doing this I could potentially create a spanning-tree problem. I have thought about NOT putting the wireless vlan on every trunk (just 1 of the 2 trunks to each closet). I would sacrafice redundancy in this case, but other than purchasing WLSM for my core 6500's I don't know how to accomplish this. In my current environment my laptops roam between access points and must go through the DHCP process. This causes about a 5-10 second interruption.
I understand from your query that you are looking for information on how to configure Vlans on your access point to segment the network. Have a look at the following document URL. This explains the step by step configuration for VLAN configuration on APs.
We are already doing several VLANs on a single access point. My question is actually more of an architecture question. I want to be able to do layer 2 roaming in a layer 3 network. I am also not ready to shell out big $ on WLSM modules in a 6500 switch.
Option 2: Involves $$$, but you could look at Cisco's new 4400-series Wireless LAN Controllers and Lightweight Access Point Protocol deployment. Very neat, and provides roaming and centralized control. URL follows:
