4.2.6.4.7.1 Add MAC Address to List
Select Add MAC Address to List to add a MAC Address to the List.
4.2.6.4.7.2 Remove MAC Address from List
Select Remove MAC Address from List to remove a MAC Address from the List.
4.2.6.4.7.3 MAC Address List Action
This parameter defines the working mode of the MAC list:
 In the case of an Allowed list, if the MAC address is included in the list, the
SU will be able to associate itself with the AU and receive permission for
generating traffic; if it is not found in the list, it will still be associated but
without the permission to generate traffic.
 In the case of a Deny list, if the MAC address is included in the list, the SU
will be able to associate itself with the AU but will not be able to generate
traffic; otherwise (if the address is not found in the list) the SU will be
associated and will be able to generate traffic.
Possible options for this parameter are Deny and Allow.
The default is Deny.
4.2.6.4.7.4 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
