I've found some discussion on this, but nothing that's helped resolve so I'm hoping someone can help. We recently purchased a 2112 WLC, running version 220.127.116.11. I have everything running through a single port on the controller, which is connected to a trunk port on our 3750 stack. Our management VLAN is vlan 40, and AP is plugged into another port on the same switch which is an access port in vlan 40. APs appear in the controller ok, receive an IP address, but we aren't able to connect to any of the WLANs and periodically the APs will disassociate with the following messages:
|0||Thu Mar 22 09:47:51 2012||AP 'AP003a.99eb.702d', MAC: b8:62:1f:45:95:b0 disassociated previously due to AP Reset. Uptime: 0 days, 00 h 35 m 52 s . Last reset reason: operator changed 11g mode|
|1||Thu Mar 22 09:47:39 2012||AP Disassociated. Base Radio MAC:b8:62:1f:45:95:b0|
|2||Thu Mar 22 09:47:39 2012||AP's Interface:0(802.11b) Operation State Down: Base Radio MAC:b8:62:1f:45:95:b0 Cause=New Discovery|
I'm not sure if that's related to why we can't connect to the WLANs or not...
Another wrinkle is that if we plug in the AP directly to one of the PoE ports on the controller, it all works perfectly. Any ideas? I'm guessing its something switch-related since the only difference is that we're not going through the switch when it works.
Thanks in advance,
