802.1p binding vpn-instance

Function

The 802.1p binding vpn-instance command binds a VPN instance to an 802.1p priority so that packets carrying the 802.1p priority are sent to this VPN.

The undo 802.1p binding vpn-instance command removes the binding between VPN instances and 802.1p priorities.

By default, VPN instances are not bound to 802.1p priorities so that packets are not sent to VPNs based on 802.1p priorities.

This command is supported only on the NetEngine 8000 F1A.

Usage Guidelines

Usage Scenario

Service packets carry 802.1p values to identify their priorities. The BRAS can identify service priorities based on the 802.1p values of received Layer 2 service packets and transmit the service packets to corresponding VPNs. To allow this, enable a BAS interface to transmit packets to different VPNs based on 802.1p priorities of the packets and also run the 802.1p binding vpn-instance command to bind a VPN instance to an 802.1p priority.

Prerequisites

A BAS interface has been enabled to transmit packets to different VPNs based on 802.1p priorities of the packets using the 802.1p-to-vpn command.

Precautions

This command is supported only on the admin VS.

If the user-VLAN sub-interface terminates two VLAN tags, services enter different VPN instances based on the 802.1p in the outer VLAN tag.

Example

# Bind VPN instance huawei to 802.1p priority 2 on the user-VLAN sub-interface terminates packets that carry VLAN 100.
