BVI1 is down, line protocol is down

Can anyone tell me how to bring this interface back up? It's a 1252 with 80211.n.

I started configuring it with CLI and then was using the web interface. I made a change on the web interface and it caused the AP to hang. I rebooted it and can access via Hyperterminal, but I cannot ping the IP address nor bring it up in the web interface any longer.

I tried the "No shut" command in the BVI1 interface.

Have you tried erasing the config?

What change did you make in the GUI when the AP hung?

You can always try to go in through the CLI issue a write erase command, which will erase the current config and you can then redo the config.

Alternately just try reconfiguring the BVI1 interface and verify all your other settings.

Hi Steve,

Check that the management VLAN's bridge group is 1 so it ties in with the BVI1, I vaquely recall this getting out of step on one of our APs that started misbehaving during reconfiguration.

Hope this is helpful
