Maintaining GRE

Maintaining GRE

This section describes how to reset the statistics of a tunnel interface and monitor the GRE running status.

Resetting the Statistics of a Tunnel Interface

When you need to reset the statistics of a tunnel interface, you can run the reset commands to clear the Keepalive packets and Keepalive Response packets sent and received by a GRE tunnel interface.


  • Reset statistics about Keepalive packets on the tunnel interface.
    1. Run system-view

      The system view is displayed.

    2. Run interface tunnel interface-number

      The tunnel interface view is displayed.

    3. Run reset keepalive packets count

      Reset the statistics on Keepalive packets on the tunnel interface.


      You can run the reset keepalive packets count command only in the tunnel interface view, and the interface tunnel protocol must be GRE.

Monitoring the Running Status of GRE

In routine maintenance, you can run the GRE related display commands to view the GRE running status.


  • Run the display interface tunnel [ interface-number ] command to check the tunnel interface running status.
  • Run the display ip routing-table vpn-instance vpn-instance-name command to check the VPN routing table on the PE.
  • Run the display ip routing-table command to check the routing table on the CE.
  • Run the ping [ -a source-ip-address | -vpn-instance vpn-instance-name ] * host command to check whether two ends of the tunnel can communicate with each other.
  • Run the display keepalive packets count command to check the numbers of Keepalive messages and Keepalive response messages sent and received by a GRE tunnel interface.
