Attribute
Meaning
Bridge Entry
Timeout
Specify the appropriate bridge timeout for correct network
operation with the existing network infrastructure. Timeout
occurs when the BHM encounters no activity with the BHS
(whose MAC address is the bridge entry) within the interval that
this parameter specifies. The Bridge Entry Timeout must be a
longer period than the ARP (Address Resolution Protocol) cache
timeout of the router that feeds the network.
This parameter governs the timeout interval, even if a router
in the system has a longer timeout interval. The default value
of this field is
25 (minutes).
An inappropriately low Bridge Entry Timeout setting may lead
to temporary loss of communication with some end users.
Bridging
Functionality
Disable
allows user to use redundant BHs without causing
network addressing problems. Through a spanning tree protocol,
this reduces the convergence time from 25 minutes to few
seconds. However, you must disable bridge table filtering as only
a deliberate part of your overall network design since disabling it
allows unwanted traffic across the wireless interface.
Specify the appropriate bridge timeout for correct network
operation with the existing network infrastructure. The Bridge
Entry Timeout must be a longer period than the ARP (Address
Resolution Protocol) cache timeout of the router that feeds the
network.
Frame Timing
Pulse Gated
If this BHS extends the sync pulse to a BH master or an BHM,
select either
Enable
—If this BHS loses sync from the BHM, then
do not
propagate a sync pulse to the BH timing master or other BHM.
This setting prevents interference in the event that the BHS loses
sync.
Disable
—If this BHS loses sync from the BHM, then propagate
the sync pulse to the BH timing master or other BHM.
Multicast
Destination
Address
Using Link Layer Discovery Protocol (LLDP), a module exchanges
multicast addresses with the device to which it is wired on the
Ethernet interface. Although some switches (CMMmicro, for
example) do not pass LLDP addresses upward in the network, a
radio can pass it as the value of the
Multicast Destination
Address
parameter value in the connected device that has it
populated.
