Hello.
I'm having this wierd problem with an IP phone behind a WGB. The setup is like this:
Cisco controller -> Switch -> switch -> AP (Air LAP1142) -> WGB (Air LAP 1262) -> switch -> IP phone.
The phone works, sometimes. Sometime for days, sometime for hours, then it disconnects and what I have to do then to get it working again is to run this command on the bridge. "no workgroup-bridge unified-vlan-client", then wait for it to disassociate, then run "workgroup-bridge unified-vlan-client" and after that it gets a stable connection (for a undetermined amount of time).
I think I have tried everything by now and I would be extremly grateful for any help regarding this issue.
Here´s the WGB config:

Are there other devices on the switch that are disconnecting as well ? Do you have wcs ? Does it show the bridge disconnecting ?

There are other devices connecting to the switch, but in the native vlan, and they are not disconnecting. The bridge is not disconnecting from the AP either. It does not matter if its an IP phone, or a computer either. And yes, we have wcs, but it´s wierd because the devices on the native works perfectly.

"clear bridge" also makes the phone reconnect.
Anyone with any information about this, please?
