Attribute Meaning
ARP
then the Send Untranslated ARP parameter can be:
Disabled - so that the AP will overwrite the MAC address in
Address Resolution Protocol (ARP) packets before forwarding
them.
Enabled - so that the AP will forward ARP packets regardless
of whether it has overwritten the MAC address.
If the Translation Bridging parameter is set to Disabled,
then the Send Untranslated ARP parameter has no effect.
SM Isolation
Prevent or allow SM-to-SM communication by selecting from
the following drop-down menu items:
Disable SM Isolation (the default selection). This allows full
communication between SMs.
Block SM Packets from being forwarded. This prevents
both multicast/broadcast and unicast SM-to-SM
communication.
Block and Forward SM Packets to Backbone. This not only
prevents multicast/broadcast and unicast SM-to-SM
communication but also sends the packets, which otherwise
are handled SM to SM, through the Ethernet port of the AP.
Packet Flooding Enabled: All unknown Unicast packets (no entry in the AP’s
bridge table) received via the AP’s Ethernet LAN interface are
forwarded to registered SMs. If the target device is situated
beneath a particular SM, when the device responds the SM
and AP will learn and add the device to their bridge tables so
that subsequent packets to that device is bridged to the proper
SM.
Disabled: All unknown Unicast packets (no entry in the AP’s
bridge table) received via the AP’s Ethernet LAN interface are
discarded at the AP.
Update
Application
Address
Enter the address of the server to access for software updates
on this AP and registered SMs.
Prioritize TCP ACK To reduce the likelihood of TCP acknowledgement packets
being dropped, set this parameter to Enabled. This can
improve throughput that the end user perceives during
transient periods of congestion on the link that is carrying
acknowledgements. This parameter, when enabled, can be
particularly useful when running bi-direction FTP sessions
over the link. If a link is primarily used for video surveillance,
it is recommended to set this parameter to Disable.
Multicast
Destination
Using Link Layer Discovery Protocol (LLDP), a module
exchanges multicast addresses with the device to which it is
