Using PW Ping to Check PW Connectivity on a VPLS Network

Using PW Ping to Check PW Connectivity on a VPLS Network

After you configure a virtual private LAN service (VPLS) network, use pseudo wire (PW) ping to monitor PW connectivity on the VPLS network.

Prerequisites

Before you run the ping vpls command to check PW connectivity, ensure that the VPLS network has been configured correctly.

Context

To check whether a PW on the VPLS network is faulty, run the ping vpls command.

Procedure

  1. To locate the faulty node on the VPLS network, run either of the following commands as required:

    • In Kompella mode, run:
      ping vpls [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v | -g ] * vsi vsi-name local-site-id remote-site-id [ bypass -si interface-type interface-number ]
    • In Martini mode, run:

      ping vpls [ -c echo-number | -m time-value | -s data-bytes | -t timeout-value | -exp exp-value | -r reply-mode | -v | -g ] * vsi vsi-name peer peer-address [ negotiate-vc-id vc-id ] [ control-word [ remote remote-address remote-pw-id [ sender sender-address ] ] ] [ bypass -si interface-type interface-number ]

    The ping vpls command output contains the following information:

    • Response to each ping VPLS packet. If no response packet is received after the corresponding timer expires, the message reading "Request time out" is displayed. If a response packet is received, the number of data bytes, packet sequence number, TTL, and response time are displayed.

    • Final statistics: include the number of sent packets, number of received packets, percentage of sent packets with failed responses, and minimum, maximum, and average response times.

    For example:

    <HUAWEI> ping vpls vsi a2 peer 10.1.1.1
        PW PING : FEC 128 PSEUDOWIRE (NEW). Type = vlan, ID = 2 : 100 data bytes, press CTRL_C to break
        Reply from 10.1.1.1: bytes=100 Sequence=1 time=60 ms
        Reply from 10.1.1.1: bytes=100 Sequence=2 time=50 ms
        Reply from 10.1.1.1: bytes=100 Sequence=3 time=60 ms
        Reply from 10.1.1.1: bytes=100 Sequence=4 time=60 ms
        Reply from 10.1.1.1: bytes=100 Sequence=5 time=60 ms
    
      --- FEC: FEC 128 PSEUDOWIRE (NEW). Type = vlan, ID = 2 ping statistics ---
        5 packet(s) transmitted
        5 packet(s) received
        0.00% packet loss
        round-trip min/avg/max = 50/58/60 ms
