When show controllers dot110 is entered, it displays a serial number with a junk character.
•
CSCsc21018—1400 Series bridge shows non-root IP address as 0.0.0.0
When non-root bridges are configured to use DHCP IP Address, the show dot11 association output
shows non-root IP address as 0.0.0.0 despite the fact that IP address has been successful allocated
and received by the non-root bridge. This does not affect any IP communication of root or non-root
bridge at all.

and received by the non-root bridge. This does not affect any IP communication of root or non-root
bridge at all.
Workaround: Issuing a shutdown and no shutdown command on the non-root radio interface will
allow non-root to re-associate to the root bridge after it receives the DHCP IP address and
communicates the IP address to the root bridge.

Alternatively, use the mac-address command to set the BVI 1 interface mac-address to the same as
the non-root radio mac-address will allow root bridge to snoop the DHCP IP address and update the
association table automatically. Normally, BVI 1 mac-address is the FastEthernet mac-address of the
bridge. All IP traffic uses this BVI mac-address while root bridge keeps track of non-root with the
uplink.
