Flood Specify the Flood setting. Flood refers to the
method in which interface modules handle
unknown unicasts (traffic directed to a single
MAC Address), broadcasts (traffic directed to all
MAC Addresses) and multicasts (traffic directed
to multiple MAC Addresses) for each port.
z Upl (Uplink) – Unknown unicast, broadcast
and multicast traffic is flooded only to the
DSLAM uplink interface ports. This prevents
communication between interface ports
without the intervention of an upstream
device such as a router. If communication
between interface ports is desired, the
upstream device must be properly configured
to allow it.
z Vln (VLAN) – Unknown unicast, broadcast
and multicast traffic is flooded to the
DSLAM’s ADSL ports (within the sender's
VLAN range) in addition to the uplink
interface ports.
Ethertype Specify the Ethertype of the backbone tag added
to traffic if the backbone VLAN ID is
configured. Used only in conjunction with
backbone VLANs.
