Usage Guidelines

Usage Scenario

To enable DCN packets to pass through a Layer 2 network, run the dcn vlan command to configure a DCN VLAN. Then, the DCN VLAN ID specified in this command will be added to DCN packets before they are sent out.

Prerequisites

The DCN feature has been enabled globally using the dcn command in the system view.

Precautions

The service VLAN ID should be different from the DCN VLAN ID.

Running this command in the interface view to configure a DCN VLAN refreshes the DCN VLAN configurations of only the interface.

New configurations overwrite existing configurations.

In VS mode, this command is supported only by the admin VS.

# Configure DCN VLAN 4093 on GE 0/1/0.
