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
