display vrrp6 statistics
Function
The display vrrp6 statistics command displays statistics about Virtual Router Redundancy Protocol for IPv6 (VRRP6) Advertisement packets sent and received by a VRRP6 backup group.
Parameters
| Parameter | Description | Value |
|---|---|---|
| interface interface-name |
Specifies the type and number of an interface on which a VRRP6 backup group is configured. |
- |
| interface interface-type interface-number |
Specifies the type and number of an interface on which a VRRP6 backup group is configured. |
- |
| vrid virtual-router-id |
Specifies the ID of a VRRP6 backup group. |
The value is an integer ranging from 1 to 255. |
Usage Guidelines
Usage Scenario
After you configure a VRRP6 backup group, run the display vrrp6 statistics command to view statistics about VRRP6 Advertisement packets sent and received by the VRRP6 backup group.
Precautions
To view statistics about packets sent and received by a VRRP6 backup group within a certain period, run the reset vrrp6 statistics command to clear the original statistics.
Example
The actual command output varies according to the device. The command output here is only an example.
