the required settings for each interface, click Apply.
Figure 3-111 Configuring VLANs per Port
CLI – This example sets port 3 to accept only tagged frames, assigns PVID 3 as the
native VLAN ID, enables GVRP, sets the GARP timers, and then sets the switchport
mode to hybrid.
Configuring IEEE 802.1Q Tunneling
IEEE 802.1Q Tunneling (QinQ) is designed for service providers carrying traffic for
multiple customers across their networks. QinQ tunneling is used to maintain
customer-specific VLAN and Layer 2 protocol configurations even when 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.
A service provider’s customers may have specific requirements for their internal
VLAN IDs and number of VLANs supported. VLAN ranges required by different
customers in the same service-provider network might easily overlap, and traffic
passing through the infrastructure might be mixed. Assigning a unique range of
VLAN IDs to each customer would restrict customer configurations, require intensive
processing of VLAN mapping tables, and could easily exceed the maximum VLAN
limit of 4096.
