The default is Active
 MAC Address Black List (AU only) - Enables to define units that are
not authorized to receive services. The AU will not provide services
to a unit whose MAC Address is included in the black list. This
feature enables to disconnect units from the services in cases such
as when the user had fraudulently succeeded to configure the unit
to values different than his subscription plan. The black list can
include up to 100 MAC Addresses.
 Add MAC Address to Black List - To add a MAC Address to the
Black List.
 Remove MAC Address from Black List - To remove a MAC
Address from the Black List.
 Show MAC Address Black List - To display the current list of
MAC Addresses included in the black list.
 Wireless Trap Threshold - Enables to define the threshold for the
wireless quality traps: The brzaccAUWirelessQualityTRAP or the
brzaccSUWirelessQualityTRAP indicate that the quality of the
wireless link has gone below or above the specified threshold.
For AU the threshold is in percents of retransmissions. For SU the
threshold is in RSSI units, indicating the quality of the received
signal. Appendix D provides information on RSSI to dBm
conversion.
 Send Roaming SNAP (SU- only, except to SU-BD and SU-BD1V) -
This feature is applicable only to mobile units that can roam among
AUs. The feature enables fast distribution of the new location for all
clients that are behind the SU.
When enabled, the SU will send multicast SNAP messages via the
wireless link each time it associates with an AU, except to 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.
NOTE:
When Best AU support is enabled, it is recommended to use Active Scanning.
If passive scanning is used, the SU may not hear the best AU (or the preferred
AU). The higher the number of hopping channels, the higher the probability
that the SU will not hear the best (or preferred) AU when passive scanning is
used.
