    Monitoring L2VPN Interfaces for VPWS

    Purpose

    Display configuration and status information for interfaces on the router that are that are configured to be members of VPWS L2VPNs in the current VR. You can display information for a specific L2VPN interface, for all L2VPN interfaces in the specified VPWS instance, or for all L2VPN interfaces in all VPWS instances. The detail keyword displays detailed information about the specified L2VPN interface or all L2VPN interfaces.

    Action

    To display L2VPN interface information for a particular VPWS instance:

    host1#show l2vpn interface instance l2vpn1
    MPLS shim interface ATM2/0.100
      ATM circuit type is AAL5
      Member of L2VPN instance l2vpn1
      Local site ID is 1
      Remote site ID is 2
      Control word is preferred by default
      Do send sequence numbers by default
      Relay format is atm-aal5-sdu-vcc by default
      Administrative state is enabled
      Operational state is up
      Operational MTU is 9180
      MPLS shim interface UID is 0x2d000007
      Lower interface UID is 0x0b000005
      Condensed location is 0x00020000
      Received:
        3 packets
        204 bytes
        19 errors
        0 discards
      Sent:
        0 packets
        0 bytes
        0 errors
        0 discards
      queue 0: traffic class best-effort, bound to atm-vc ATM2/0.100
        Queue length 0 bytes 
        Forwarded packets 0, bytes 0
        Dropped committed packets 0, bytes 0
        Dropped conformed packets 0, bytes 0
        Dropped exceeded packets 0, bytes 0
