25.4 VLAN TLS Commands
Use these commands to configure Transparent LAN Service (TLS) on the IES. Transparent LAN
Service (also known as VLAN stacking or Q-in-Q) allows a service provider to distinguish multiple
customers VLANs, even those with the same (customer-assigned) VLAN ID, within its network.
Use TLS to add an outer VLAN tag to the inner IEEE 802.1Q tagged frames that enter the network.
By tagging the tagged frames ("double-tagged" frames), the service provider can manage up to
4,093 VLAN groups with each group containing up to 4,093 customer VLANs. This allows a service
provider to provide different services, based on specific VLANs, for many different customers.
A service provider's customers may require a range of VLANs to handle multiple applications. A
service provider's customers can assign their own inner VLAN tags to traffic. The service provider
