be added to a second bridge, which includes other switch ports or software
interfaces. Some approaches to ensure that the forwarding domain for traffic
belonging to the VLAN upper interfaces are managed properly:
+
* If forwarding destinations can be managed per VLAN, the hardware could be
configured to map all traffic, except the packets tagged with a VID
belonging to a VLAN upper interface, to an internal VID corresponding to
VID 0 in its database.
When the bridge has VLAN filtering enabled and a PVID is not configured on the
-ingress port, untagged 802.1p tagged packets must be dropped. When the bridge
+ingress port, untagged and 802.1p tagged packets must be dropped. When the bridge
has VLAN filtering enabled and a PVID exists on the ingress port, untagged and
priority-tagged packets must be accepted and forwarded according to the
bridge's port membership of the PVID VLAN. When the bridge has VLAN filtering
