I'm configuring an AP1130 AG with two vlans: one for the managemement and one for the WiFi users. The customer does not want to use the VLAN 1. I created radio interface 0.<management vlan> and 0.<WiFi VLAN> using two specific bridge-groups (different from 1). My question is the following: under the main radio interface there are the references of the bridge group 1 that I did not use. Can I leave it or must I replace it with the bridge group that I used for the management vlan?
Yes, you should remove all references to bridge-groups on your actual Dot0 and Fa0 interfaces. It's also necessary to create subinterfaces on your Fa0 interface, just in case you didn't do that.
Keep in mind that you should use bridge-group 1 on your native VLAN, so if your management VLAN is the native then it should be on bridge-group 1. Either way, you should have a subinterface on Fa0 for your native VLAN, otherwise you won't be able to telnet to the AP.
If you want to post your configuration, we can probably be of more help. Hopefully that works for you though.
SO I must to remove under the dot11 radio 0 and 1 the references for the bridge-group1? if under the fast ethernet 0.102 I put bridge group 1 I lose the connection from the switch. It seems a link between bridge group 1 and vlan 1
