In my AP1100 I am setting up using web interface, and decided to look at it with cli.

I found the interface I thought was primary ethernet as BVI1.. and FastEthernet0 did not have the IP i set .

interface FastEthernet0

no ip address

no ip route-cache

duplex auto

speed auto

bridge-group 1

no bridge-group 1 source-learning

bridge-group 1 spanning-disabled


interface BVI1

ip address

no ip route-cache


ip default-gateway

Thanks for the help..

BVI = Bridged Virtual Interface.

It's a logic mechanism that allows a collection of interfaces (like B/G/A radios, Ethernet, etc) to be collectively bridged to each other (the collection of interfaces appear as a single logical interface) and routed to the other interfaces (per protocol).

In the case of the AP, it would allow all of the interfaces to be collectively assigned an IP address (and / or sub-divided into sub-interfaces for multi-SSID / multi-VLAN configurations) for management.
