LABEL DESCRIPTION
Active Enable the switch button to enable VLAN stacking on the Switch.
Port This field displays the port number.
* Settings in this row apply to all ports.
Use this row only if you want to make some settings the same for all ports. Use this row first to set the
common settings and then make adjustments on a port-by-port basis.
Note: Changes in this row are copied to all the ports as soon as you make them.
Role Select Normal to have the Switch ignore frames received (or transmitted) on this port with VLAN
stacking tags. Anything you configure in SPVID and Priority of the Port-based QinQ or the Selective
QinQ screen are ignored.
Select Access to have the Switch add the SP TPID tag to all incoming frames received on this port.
Select Access for ingress ports at the edge of the service provider's network.
Select Tunnel (available for Gigabit ports only) for egress ports at the edge of the service provider's
network. Select Tunnel to have the Switch add the Tunnel TPID (HEX) tag to all outgoing frames
sent on this port.
In order to support VLAN stacking on a port, the port must be able to allow frames of 1526 Bytes
(1522 Bytes + 4 Bytes for the second tag) to pass through it.
