Timing Mode
Select Timing Slave. This BH will receive sync from another source. Whenever you
toggle this parameter to Timing Slave from Timing Master, you should also do the
following:
1. Make no other changes in this or any other interface page.
2. Save this change of timing mode.
3. Reboot the BH.
RESULT:The set of interface web pages that is unique to a BHS is made available.
NOTE:
In a BHS that cannot be converted to a BHM, this parameter is not present (for
example, in a BHS with Hardware Scheduling and Series P8 hardware.)
Link Speeds
Specify the type of link speed for the Ethernet connection. The default for this parameter
is that all speeds are selected. The recommended setting is a single speed selection for
all APs, BHs, and SMs in the operator network.
Webpage Auto 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 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 should 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.
CAUTION!
An inappropriately low Bridge Entry Timeout setting may lead to temporary loss
of communication with some end users.
Bridging Functionality
Select whether you want bridge table filtering active (Enable) or not (Disable) on this
BHS. Selecting Disable allows you to use redundant BHs without causing network
addressing problems. Through a spanning tree protocol, this reduces the convergence
time from 25 minutes to mere seconds. However, you should disable bridge table filtering
as only a deliberate part of your overall network design. Otherwise, disabling it allows
unwanted traffic across the wireless interface.
