(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.
Authentication Key
Only if the AP to which this SM will register requires authentication, specify the key that
the SM should use when authenticating:
◦ Use Default Key specifies the predetermined key for authentication in the BAM
server. See Authentication Manager Capability on Page 307.
◦ Use This Key specifies the 32-digit hexadecimal key that is permanently stored
on both the SM and the BAM database.

NOTE:
In Release 4.2.2 and earlier releases, if you enter the same key but as
fewer than 32 digits in the SM and BAM database, the SM cannot
authenticate despite the match. In Release 4.2.3 and later releases, the
SM and BAM server pad the key of any length by the addition of leading
zeroes, and if the entered keys match, authentication attempts succeed.
However, Canopy recommends that you enter 32 characters to achieve
the maximal security from this feature.
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 other 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 other AP.
