3.3.2.5 Beacon Interval
The Bridge’s radios transmit beacons at regular intervals to
announce their presence on the network. You can configure
the number of milliseconds between beacons in whole
numbers between
25 and 1000 . You cannot disable the
beacon.
The default beacon interval is 100 milliseconds.
3.3.2.6 Multicasting
Wireless is an inherently broadcast medium. A multicast
packet, like any other, is broadcast (by the root Bridge) to all
nodes (non-root Bridges) on the wireless network. Each non-
root Bridge then examines the packet and:
‹ If the Bridge is an intended receiver, it accepts the packet.
and/or
‹ If the Bridge is serving as a repeater for an outlying Bridge
that is an intended receiver, it passes the packet along this
route.
or
‹ If the Bridge is neither an intended receiver nor the
repeater for an intended receiver, it drops the packet.
Non-root Bridges on which Multicast is disabled will drop all
multicast packets.
The Multicast function applies exclusively to non-root Bridges,
and so can only be Enabled on Bridges with a Radio Mode
setting of Bridge and a Bridge Mode setting of Non-Root .
The Multicast field is grayed out for Bridges with a Radio Mode
of AP or with a Bridge Mode of Root .
The Multicast field is also grayed out for Bridge’s with STP
Enabled on the LAN SETTINGS screen. Because STP requires
multicasting capability, Multicast is automatically Enabled (and
the field that configures the setting is grayed out) when STP is
