802 VLAN Commands
Uplink Port Behavior
If a single-tagged (SP tagged) or double-tagged (SP tag as outer tag) packet
ingresses an uplink port, the switch strips the outer tag prior to forwarding it
to the respective access ports.
If an untagged or single tagged (802.1Q tagged) packet egresses an uplink
port, the switch tags it with the configured ethertype and service provider
VLAN ID taken from the service port PVID.
Access Port Behavior
Ingress packets on an access port are always tagged by the switch. Packets are
tagged on ingress with the configured ethertype and the service provider ID
taken from the PVID of the service provider port. On egress, the access port
strips the outer tag belonging to service provider VLANS.
