different customers use the same internal VLAN IDs. This is
accomplished by inserting Service Provider VLAN (SPVLAN) tags into
the customer’s frames when they enter the service provider’s network, and
then stripping the tags when the frames leave the network. QinQ tunneling
expands VLAN space by using this VLAN-in-VLAN hierarchy, preserving
the customer’s original tagged packets, and adding SPVLAN tags to each
frame (also called double tagging). Ports on the switch can be set to
support QinQ when providing a direct link to a service provider's network.
Creating VLANs and Assigning Port Members
To create a new VLAN, enter an identifier in the Add VLAN Group table,
click the Add button, and then configure the port or static trunk members
on the 802.1Q VLAN Group page. To modify the membership settings
for an existing VLAN, select a VLAN from the VLAN Group List, and
click Modify. Each row in the VLAN membership table corresponds to
one port or static trunk. Trunked ports cannot be configured individually.
Also, note that the VLAN membership of dynamically configured LACP
trunks cannot be modified.
