Router Dest Mac Filtering Menu
The Select Destination Mac Filters option from the Bridge User Port Provisioning Menu (refer
to
“Bridge User Port Provisioning Menu” on page 5-13) allows filtering of ingress traffic of the
subscriber ports based on the configured Mac addresses (see Figure 5-13 ). Also known as
white listing because traffic other than the configured Mac addresses is discarded and traffic
with the configured Mac addresses is forwarded. Broadcast traffic is forwarded in either case.
Selecting
Disabled
allows the filtering to be turned off even if the Mac addresses are configured.
