display udp statistics
Function
The display udp statistics command displays UDP packet statistics.
The display udp ipv6 statistics command displays IPv6 UDP packet statistics.
Usage Guidelines
Usage Scenario
UDP is a communications protocol used for packet exchanging on the Internet. It uses the simplest transmission model to send messages from one user application to another. To view IPv6 UDP packet statistics, run the display udp ipv6 statistics command. The following information will be displayed:
- Number of received and sent packets
- Number of discarded packets
- Number of redirected packets
Precautions
The number of packets received by a device includes the number of packets forwarded to another device, the number of packets sent to the upper layer on the device, and the number of packets discarded by the device.
Example
The actual command output varies according to the device. The command output here is only an example.
