wired port when moving between APs of the same group.This
is useful when two or more APs are on the same subnet.

AP.

The
MAC
label may appear twice if a P23 redundant Access Point is
installed at that location. In this case, one
MAC
statement provides the
MAC address of the A radio and the other
MAC
statement provides the
MAC address of the B radio. The
CHANNELS
statement only needs to be
present if the channel selection feature is used at the Access Point to
limit which channels are active. If all channels are used, you can leave
out the
CHANNELS
statement. You can leave out the
BW
statement for
APs that are configured to 1.75 MHz bandwidth. You can also leave out
the
DUR
statement for APs that are configured with a 20 millisecond
frame duration.
