DESCRIPTION
Active
Select this checkbox to enable VLAN stacking on the Switch.
Port
The port number identifies the port you are configuring.
*
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 Port to have the Switch add the SP TPID tag to all incoming frames received on
this port. Select Access Port for ingress ports at the edge of the service provider's network.
Select Tunnel Port (available for Gigabit ports only) for egress ports at the edge of the service
provider's network. Select Tunnel Port to have the Switch add the Tunnel TPID 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.
