Usage Scenario
The User Datagram Protocol (UDP) is a simple protocol that exchanges packets on the Internet. You can run the display udp ipv6 statistics command to view statistics about sent and received UDP6 packets.
Precautions
The total number of packets received by the device includes the number of forwarded packets, number of packets delivered by the device to the upper layer, and number of discarded packets.
