Circuit Configuration

Parameter

Description

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.
