# Vp (Virtual port): An address of a node behind an associated
SU. For these addresses, learned from the wireless port, the
address of the applicable SU is also displayed (in parenthesis).
# St (Static): An associated SU. For these entries, the SW version
of the SU is also displayed.
# Sp (Special): 7 addresses that are always present, which
include:
! The MAC address of the AU, which appears twice as it is
learned from both the Ethernet and wireless ports.
! The MAC address of the internal Operating System stack,
which also appears twice.
! Alvarion's Multicast address (01-20-D6-00-00-01, which also
appears twice. The system treats 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) and the Associated Subscriber
Units Database (Association Info). Each database includes the
following information:
# The current number of entries. For Bridging Info this includes
the Et (Ethernet) and the Vp (Virtual ports) entries. For
Association Info this is the number of currently associated SUs.
NOTE
There is no aging algorithm for associated SUs. An SU is only removed from the list of
associated SUs under the following conditions:
a. A SNAP frame is received from another AU indicating that the SU is now associated
with the other AU.
b. The SU failed to respond to a certain number of consecutive frames transmitted by
the AU and is considered to have "aged out".
# The aging time specified for entries in these tables. The aging
time for Bridging Info is as specified by the Bridge Aging Time
parameter. The default is 300 seconds. There is no aging time
for Association Info entries.
# The maximum number of entries permitted for these tables,
which are 1017 (1024 minus the number of special Sp addresses
as defined above) for Bridging Info and as specified by the
Maximum Number of Associations parameter for Association
Info. The default value of the Maximum Number of
Associations parameter is 512.
