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.
