IP Performance Configuration Commands 455
Description
Using the display udp statistics command, you can view TCP traffic statistic
information.
The command is used to display the traffic statistic information of all the active
TCP connections. Statistics information is classified into two parts: receiving and
sending, and each part can be further classified according to different types of
packets, as checksum packets and error packets, for example. Moreover there are
statistics closely related to connection, such as the number of broadcast packets.
The statistics information is organized in terms of packet.
For relate configuration, please refer to the reset udp statistics command.
Example
