Usage Guidelines

Usage Scenario

You can run the display ipv6 statistics command to view statistics on received and sent IPv6 packets.

During packet transmission, if the source node has fragmented packets, you can run this command to view the total number of IPv6 packets that are successfully fragmented and the total number of fragmented packets that have been sent, and then check whether the number of fragmented packets received by the destination node is correct.

Precautions

The total number of packets received by the device includes the number of forwarded packets, number of packets delivered by the routing device to the upper layer, and number of discarded packets.

Example

# Display IPv6 traffic statistics on the device.
