Update Enter the frequency (in seconds) for the web browser to automatically
refresh the web-based interface. The default setting is 0. The 0 setting
causes the web-based interface to never be automatically refreshed.
Bridge Entry Timeout Specify the appropriate bridge timeout for correct network operation with
the existing network infrastructure. Timeout occurs when the AP encounters
no activity with the SM (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.
Caution
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.
Bridge Table Size This parameter allows to restrict devices to connect to the SM. It is
configurable from 4 to 4096.
Note
Configure Bridge Table Restriction parameter to Drop packets if
MAC address is not in bridge table option to restrict the number
of devices configured from connecting to SM.
Bridge Table
Restriction This parameter allows to either allow or restrict devices to connect to SM
using the following options:
•
Drop packets if MAC address is not in bridge table: Select this option to
restrict communication from devices not listed in bridge table.
Forward packets even if MAC address is not in bridge table: Select this
option to allow communication from any device.
Frame Timing Pulse
Gated If this SM extends the sync pulse to a BH master or an AP, select either
Enable—If this SM loses sync from the AP, then do not propagate a sync
pulse to the BH timing master or another AP. This setting prevents
interference in the event that the SM loses sync.
Disable—If this SM loses sync from the AP, then propagate the sync pulse to
the BH timing master or another AP.
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 (CMM4, 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.
