Using Ping and Trace to Monitor Link Connectivity Within a Virtual Cluster

Using Ping and Trace to Monitor Link Connectivity Within a Virtual Cluster

If a link within a virtual cluster fails, you can locate the failure point by using ping or trace to check virtual path (VP) connectivity and using ping to monitor virtual circuit (VC) connectivity.

Using Ping to Monitor Link Connectivity Within a Virtual Cluster

This section describes how to use ping to monitor the connectivity of a virtual path (VP) or virtual circuit (VC) between the master device and a specified AP.

Procedure

  • Run:

    vping [ -c count | -exp exp-value | -m time | -t timeout | -g ] ap { ap-name | ap-address } [ primary | hot-standby ]

    The connectivity of a VP between the master device and the specified AP is monitored.

    # Monitor the connectivity of the primary VP between the master device and an AP.

    <HUAWEI> vping ap 10 primary
    
      LSP PING FEC: IPV4 PREFIX 1.1.1.9/0/ : 100  data bytes, press CTRL_C to break

        5 packet(s) received
        0.00% packet loss
        round-trip min/avg/max = 8/34/52 ms

  • Run:

    vping [ -c count | -exp exp-value | -m time | -t timeout | -g ] ap { ap-name | ap-address } interface interface-name

    The connectivity of a VC between the master device and the specified AP is monitored.

    # Monitor the connectivity of a VC between the master device and AP10.

    <HUAWEI> vping ap 10 interface GigabitEthernet1/0/0

Using Trace to Monitor the Link Connectivity Within a Virtual Cluster

This section describes how to use trace to monitor the connectivity of a VP between the master device and a specified AP.

Procedure

  1. Run:

    vtracert [ -exp exp-value | -t timeout | -g ] ap { ap-name | ap-address } [ primary | hot-standby ]

    The connectivity of a VP between the master device and the specified AP is monitored.

    # Monitor the connectivity of the primary VP between the master device and AP10.

    <HUAWEI> vtracert ap 10 primary
      TTL   Replier            Time    Type
