Usage Guidelines

Usage Scenario

To check label stack information after configuring LDP VPWS, run the display mpls label-stack vll interface command. Label stack information helps you view VPWS PW forwarding information.

Example

The actual command output varies according to the device. The command output here is only an example.

# In LDP VPWS, check label stack information about AC interface GE 0/1/0.1.
