23.10.3 Frame Tagging Examples

In the following example, both A and B are Service Provider’s Network (SPN) customers with VPN tunnels between their head offices and branch offices respectively. Both have an identical VLAN tag for their VLAN group. The service provider can separate these two VLANs within its network by adding tag 37 to distinguish customer A and tag 48 to distinguish customer B at edge device x and then stripping those tags at edge device y as the data frames leave the network.

Figure 93 Frame Tagging Example

This example shows how to configure ports 1 and 2 on the switch to tag incoming frames with the service provider’s VID of 37 (ports are connected to customer A network). This example also shows how to set the priority for ports 1 and 2 to 3.

MES-2110(config)# vlan-stacking

MES-2110(config)# interface port-channel 1,2

MES-2110(config-interface)# vlan-stacking role access

MES-2110(config-interface)# vlan-stacking spvid 37

MES-2110(config-interface)# vlan-stacking priority 3

MES-2110(config-interface)# exit

MES-2110(config)# exit

MES-2110# show vlan stacking
