The display keepalive packets count command displays the number of Keepalive packets and Keepalive response packets sent and received by the local GRE tunnel interface.
Usage Scenario
When a tunnel is a GRE tunnel, you can enable the Keepalive function to check the link connectivity. If the function is disabled, service packets are continuously forwarded through this tunnel interface when the link fails, resulting in a tunnel black hole and loss of service data.
The display keepalive packets count command allows you to view the number of Keepalive packets and Keepalive response packets sent and received through the GRE tunnel interface.
Prerequisites
The tunnel interface view has been displayed using the interface tunnel command.
The tunnel type has been set to GRE using the tunnel-protocol gre command.
The Keepalive function has been enabled for the GRE tunnel using the keepalive command.
Follow-up Procedure
Run the reset keepalive packets count command to reset the Keepalive packet statistics.
