I have tried multiple 3602 aps and get the same result. They are having trouble getting an ip and can't find the controller. I statically assigned an ip and directed it to wism2 ip. Still no go. That ap I didnt do a debug on the wism2 controller. All aps are on a different subnet and option 43 is enabled but im currently working on getting it fixed as I dont think its set up right but it still should have connected when I entered ips. Any advice???
You should setup dhcp on the same subnet as the WLC management. If you don't have a dhcp scope from a dhcp server, create one on the WiSM. Connect an ap on the same vlan as the WLC management and see if it joins. If not, console into the ap and look and post the output. The only other reason. It can be is if the ap had a mesh code in which you will see that in the output and you will need to add the Ethernet Mac address to the WLC Mac filter before it will join.
I understand Cisco says thats best practices but we have at least 30 different buildings and its impractical for us to trunk WLC mgmt across a network this large. Most of our IDF's are layer 3 closets.
Do you have 'switchport block multicast' on any of the layer 2 interfaces that would see this traffic? I had an issue recently where a bunch of 3502s could not receive DHCP addresses and this solved the issue. Here is the thread:
Thanks for your response. I have 1142's on this same subnet right now that I reboot every once in a while and move to different controllers for testing and they always resolve through our DHCP server. I would imagine if that was the issue then they would not obtain an IP address. Would that be a correct assumption? This closet I am attached to right now is a layer 2 closet and is not currently blocking any ports. We dont not issue that command on our switches.
What code is your WLCs on ? Also are you able to mirror the wired port of a problematic ap ? That could tell us if indeed the ap is trying and if the WLC responds.
