Usage Guidelines

Usage Scenario

After a VRRP group is configured, to view statistics about the received and sent VRRP Advertisement packets, run the display vrrp statistics command with the following parameters as required:

If ifType, ifNum and virtual-id parameters are not specified, you can view information about the status of all VRRP groups on the device.
If only interface ifType and ifNum parameters are specified, you can view the status of all VRRP groups on the specified interface.
If ifType, ifNum and virtual-id parameters are specified, you can view the status of the specified VRRP group on the specified interface.

Precautions

It is recommended that you run the reset vrrp statistics command to clear statistics about the received and sent VRRP Advertisement packets before you collect statistics within a specified period.

Example

The actual command output varies according to the device. The command output here is only an example.
