Command Mode Interface mode (Ethernet and port channel), Interface range mode (Ethernet and port channel) User Guidelines This command configures a customer edge (CE) port for QinQ tunneling. The dot1q-tunnel mode is an overlay on switchport access mode. In particular, configuring the access mode PVID sets the outer dot1q-tunnel VLAN ID. Changing the switchport mode to access, general, or trunk, effectively disables tunneling on the interface. Customer edge ports can be physical ports or port channels. Untagged frames received on the CE interface will be processed as if they belong to the PVID and will be transmitted out the SP interface with a single VLAN tag. Tagged frames received on the CE interface will be transmitted out the service provider (SP) interface with an outer tag containing the native VLAN ID and the inner tag as received on the CE interface. CE interfaces must be configured in dot1q-tunnel mode with the PVID configured with the outer tag (native) VLAN ID for the associated service provider (SP) interface. Configure the outer VLAN ID using the switchport access vlan command. All MAC address learning and forwarding occurs on the outer VLAN tag. The VLAN ID must be common to both the SP port and the CE ports. The service provider interface must be configured for egress tagging (trunk or general mode) with a native VLAN identical to the PVID of the associated CE ports. SP interfaces should be configured with a single VLAN ID. A trunk mode port will accept untagged packets on the native VLAN and be a member of any newly created VLANs by default. In general mode, it is possible to directly configure the port to only accept tagged packets with a single VLAN ID. It is not possible to configure an inner VLAN TPID value. The inner VLAN TPID value is always Ethernet (0x8100). Multiple groups of associated CE and SP ports can be defined by configuring the groups with unique VLAN IDs. The port mirroring logic stage occurs after the after the tag processing stage on ingress and before the tag processing stage on egress. When mirroring packets associated with SP or CE ports, the outer VLAN tag may or may not Layer 2 Switching Commands 914
