# 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:
        0 packets
        0 bytes

      queue 0: traffic class best-effort, bound to atm-vc ATM2/0.10
        Queue length 0 bytes
        Forwarded packets 0, bytes 0
        Dropped committed packets 0, bytes 0
        Dropped conformed packets 0, bytes 0
