Manual Revision: 1.0
" Sp (Special): 5 Addresses that always exist:
# The MAC address of the AU (appears twice as it is learned
from both the Ethernet and the wireless ports)
# Alvarion’s Multicast address (01:20:D6:00:00:01, also twice).
The system handles this address as a Broadcast address.
# The Ethernet Broadcast address (FF-FF-FF-FF-FF-FF)
In addition, a summary table displays information about the
Forwarding Database (Bridging Info), the Associated Subscriber
Units Database (Association Info) and the Subscriber Units that are
currently conducting a voice call (Call Info). For each of these
databases, the displayed information includes:
# The current number of entries. The number of entries in the
Bridging Info includes the Et (Ethernet) and the Vp (Virtual
ports) entries. The number of entries in the Association Info
includes the associated units.
# The aging time specified for entries in these tables (the
defaults are 300 seconds for the Bridge Aging Time, No Aging
for the Association Aging Time and 1800 seconds for the Call
Info table).
# The maximum allowed number of entries for these tables
(1019 for the Bridging Info and as specified by the Maximum
Number of Associations parameter for the Association Info
and the Call Info. The default value of the Maximum
Number of Associations is 512).
! Display Association Info – Displays details of the associated SUs.
Each entry in the list includes the following information:
" The MAC address of the associated Subscriber Unit
" The Maximum Data Rate of the SU.
" The average level of RF signals received from the Subscriber
Unit.
" The wireless status of the SU. There are three options:
# Associated
# Authenticated
# Not Authenticated (a temporary status)
Refer to Table 2-2
for details on the status of the SU during the
various stages of the association process.
NOTE:
There is no aging algorithm for associated SUs. An SU will be removed
from the associations database only upon occurrence of any of the following:
(1) The AU received from another AU a SNAP frame with the SU MAC
address indicating that the SU has become associated with the other AU, or
(2) The AU has decided that the SU aged out following its failure to
acknowledge a certain number of consecutive frames transmitted to it.
