I am seeing a strange issue with WLC 2106. Following is my setup :
Catalyst 3750 <-> WLC 2106 <-> 1131 AP
I have a physical port on 3750 configured as dot1q trunk. I have allowed all the VLANs. On 2106, I have the default interfaces configured with IP addresses. Everything is fine up to this point. When I create a dynamic interface on 2106 I lose the connectivity to my managment interface along with the AP-manager interface. However, I can ping the Dynamic interface which I created but it doesn't let me manage the controller. I believe that you can configure the dynamic interface to allow the management of controller. I don't know if this is a known bug or not but if I delete the dynamic interface I am able to restore the connectivity to the management interface.
While creating the dynamic interface for WLAN I specify it to be on the same physical port as managment which is port 1. I don't want to have two phyical links from the controller to the switch so I haven't tried to isolate the dynamic interface to point to one of the other physical interfaces. Also, this will not work if I have more than 6 vlans.
Any help is much appreciated.
