Verifying the Q-in-Q Configuration Chapter 9 Configuring Q-in-Q VLAN Tunnels Send document comments to [email protected] Verifying the Q-in-Q Configuration To display Q-in-Q tunnel and Layer 2 protocol tunneling configuration information, perform one of the following tasks: Command Purpose clear l2protocol tunnel counters [interface Clears all the statistics counters. If no interfaces if-range] are specified, the Layer 2 protocol tunnel statistics are cleared for all interfaces. show dot1q-tunnel [interface if-range] Displays a range of interfaces or all interfaces that are in dot1q-tunnel mode. show l2protocol tunnel [interface if-range | vlan vlan-id] Displays Layer 2 protocol tunnel information for a range of interfaces, for all dot1q-tunnel interfaces that are part of a specified VLAN or all interfaces. show l2protocol tunnel summary Displays a summary of all ports that have Layer 2 protocol tunnel configurations. show running-config l2pt Displays the current Layer 2 protocol tunnel running configuration. Configuration Examples for Q-in-Q and Layer 2 Protocol Tunneling This example shows a service provider switch that is configured to process Q-in-Q for traffic coming in on Ethernet 7/1. A Layer 2 protocol tunnel is enabled for STP BPDUs. The customer is allocated VLAN 10 (outer VLAN tag). switch# configure terminal Enter configuration commands, one per line.
