In the General tab of the BHM, you may set the following parameters.
Timing Mode
Select Timing Master. This BH will provide sync for the link. Whenever you toggle this
parameter to Timing Master from Timing Slave, 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 BHM is made available.
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.
Sync Input
Specify the type of synchronization for this BH timing master to use.
• Select Sync to Received Signal (Power Port) to set this BHM to receive sync
from a connected CMMmicro.
• Select Sync to Received Signal (Timing Port) to set this BHM to receive sync
from a connected CMM2, an AP in the cluster, an SM, or a BH timing slave.
• Select Generate Sync Signal where the BHM does not receive sync, and no AP
or other BHM is active within the link range.
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. The Bridge Entry Timeout should be a longer period than the ARP
(Address Resolution Protocol) cache timeout of the router that feeds the network.
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
BHM. 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.
