Configuring an Interface to Allow Packets with Specified VLAN IDs to Pass

To enable users to communicate through a carrier network, configure interfaces on provider edges (PEs) that are connected to the carrier network to allow the passing of packets with specified virtual local area network (VLAN) IDs.

Context

Perform the following steps on PEs.

Procedure

Run system-view
The system view is displayed.
Run interface interface-type interface-number
The view of the interface connected to the carrier network is displayed.
Run port trunk allow-pass vlan { { vlan-id1 [ to vlan-id2 ] } &<1-10> | all }
The interface connected to the carrier network is configured to allow the passing of packets with specified VLAN IDs.

The specified VLAN IDs must be the same as the outer VLAN IDs carried in BPDUs that the PE receives.
Run commit
The configuration is committed.
