Comment
DFS selects the radio
channel most likely
to minimize
interference with
military radar.
—
—
Fragment counter is
in units of
fragmented packets.
Minimizes delay
propagation.
—
World mode on the
client side updates a
client with the
channels of the
specified domain.
The Cisco 3200
Series router is
limited to fixed
channels, so world
mode is not available
on the client side.
Enables operation
with non-Cisco
access points.
Support is enabled
only when universal
workgroup bridge
mode is enabled.
