# Monitoring MPLS Minor Interfaces

#### Purpose

Display status and configuration information about MPLS minor interfaces.

The show mpls interface minor command displays the same information.

#### Action

To display information about MPLS minor interfaces:

    host1:pe1#show mpls minor-interface
    MPLS minor interface pe1-to-pe2 (transmit)
      Stacked on MPLS major ATM2/0.10
      Operational state is up
      Sent:
