Chapter 4 - Operation and Administration
4.2.6.4.7.5 Show MAC Address List
Select Show MAC Address List to display the current list of MAC Addresses
included in the List and the selected List Action.
4.2.6.4.8 Roaming Option (SU only)
The Roaming Option defines the roaming support of the unit. When roaming is
not expected, it is preferable to set this parameter to Disable. This will cause the
unit to start scanning for another AU after losing connectivity with the current
AU only after 7 seconds during which no beacons were received from the current
AU. This will prevent scanning for another AU in cases where no beacons were
received due to a short temporary problem.
When set to Enable, the SU will wait only one second before it starts scanning for
another AU. In addition, when the Roaming Option is enabled, the SU will send
Roaming SNAP messages upon associating with a new AU. This enables fast
distribution of the new location for all clients that are behind the SU. In this case,
the SU will send multicast SNAP messages via the wireless link each time it
associates with a new AU, except for the first association after reset. The SU will
send one SNAP message for each client learned on its Ethernet port, based on its
bridging table. In the SNAP message the clients' MAC address is used as the
source address. The AU that receives this SNAP message learns from it the new
location of the clients. It forwards the SNAP to other AUs and Layer-2 networking
equipment via its Ethernet port, to facilitate uninterrupted connectivity and
correct routing of transmissions to these clients. The new AU as well as the
previous AU with which the SU was associated, will forward the SNAP messages
to all other SUs associated with them.
The default is Disable.
4.2.6.4.9 Ports Control (SU only)
The Ports Control sub-menu includes the Ethernet Port Control option:
4.2.6.4.9.1 Ethernet Port Control
The Ethernet Port Control option allows enabling or disabling non-management
traffic to/from the Ethernet port. When changed to Disable, all current data
sessions will be terminated. The unit is still manageable via the Ethernet port
even if it is disabled for data traffic.
The default selection is Enable.
4.2.6.4.10 Show Bridge Parameters
The Show Bridge Parameters option displays the current values of the Bridge
parameters.
