dot1q vid

Function

The dot1q vid command specifies the VLAN ID for packets on a sub-interface for dot1q VLAN tag termination, to which a BFD session is bound.

The undo dot1q command deletes the VLAN ID specified for packets on a sub-interface for dot1q VLAN tag termination, to which a BFD session is bound.

By default, no VLAN ID is specified.

Usage Guidelines

Usage Scenario

During the configuration of a BFD session, after the BFD session bound to a sub-interface for dot1q VLAN tag termination, the dot1q command can be run to specify a VLAN ID to ensure that packets are sent over the correct VLAN.

Prerequisites

Before using the dot1q command,

The control-vid command must be run on the sub-interface for dot1q VLAN tag termination, to which the BFD session is bound. Otherwise, the dot1q command will fail to be configured.
Run the dot1q termination vid command on the sub-interface for dot1q VLAN tag termination, to which the BFD session is bound. Otherwise, the dot1q command will fail to take effect after being configured.
The dot1q command is applicable to the sub-interface for dot1q VLAN tag termination, to which the multicast BFD session is bound. This requires that the bfd bind peer-ip default-ip command be run during the establishment of the BFD session.

Example

# Set the VLAN ID to 1 for packets on the sub-interface for dot1q VLAN tag termination, to which the multicast BFD session named test is bound.
