Subject: RE: Catalyst Switch and Wireless AP - 802.1q Trunk... Hello I think this can be a error on Documentation. You have to force the native vlan to bridge-group 1, but you can use whatever native vlan you wish. (At least I do it, and it works!). You can argue if you should create the Dot11radio subinterface that belongs to management. I personally create it and shut it down, just for keeping stuff organized. See the config below. interface Dot11Radio0 no ip address no ip route-cache ! encryption vlan 511 mode ciphers wep128 ! broadcast-key vlan 511 change 1800 ! ! ssid e-U vlan 511 max-associations 20 authentication open eap RADIUS_AUTH authentication network-eap RADIUS_AUTH accounting RADIUS_ACC mobility network-id 511 ! ssid guest_e-U vlan 510 max-associations 10 authentication open guest-mode mobility network-id 510 ! short-slot-time speed basic-1.0 basic-2.0 basic-5.5 6.0 9.0 basic-11.0 12.0 18.0 24.0 36.0 48.0 54.0 rts threshold 2312 station-role root no cdp enable ! interface Dot11Radio0.510 encapsulation dot1Q 510 no ip route-cache no cdp enable bridge-group 10 bridge-group 10 subscriber-loop-control bridge-group 10 block-unknown-source no bridge-group 10 source-learning no bridge-group 10 unicast-flooding bridge-group 10 spanning-disabled ! interface Dot11Radio0.511 encapsulation dot1Q 511 no ip route-cache no cdp enable bridge-group 11 bridge-group 11 subscriber-loop-control bridge-group 11 block-unknown-source no bridge-group 11 source-learning no bridge-group 11 unicast-flooding bridge-group 11 spanning-disabled ! interface Dot11Radio0.593 description -=SHUTDOWN=- encapsulation dot1Q 593 native no ip route-cache shutdown no cdp enable bridge-group 1 bridge-group 1 subscriber-loop-control bridge-group 1 block-unknown-source no bridge-group 1 source-learning no bridge-group 1 unicast-flooding bridge-group 1 spanning-disabled ! interface FastEthernet0 no ip address no ip route-cache duplex auto speed auto ---
