In order to integrate this extended filtering behavior with the
needs of regions of the network that support only Basic
Filtering Services, Bridges that support Extended Filtering
Services can be statically and dynamically configured to modify
their filtering behavior on a per-group MAC address basis, and
also on the basis of the overall filtering service provided by
each outbound Port with regard to multicast frames. The latter
capability permits configuration of the Ports default forwarding

configured, then it is assumed that the relay VID is the
same value as the local VID.

VID Translation Configuration object configures the Local
VID to Relay VID mapping on ingress only. If an Egress VID
translation is not supported, the VID Translation
Configuration object defines a single bidirectional mapping.
In this case, the Bridge should not allow multiple keys
('local-vid') mapped to the same 'reelay-vid' value.";
