15.3 Troubleshooting IP Performance

Fault: IP layer protocol works normally but TCP and UDP cannot work normally.
Troubleshoot: In the event of such a fault, you can enable the corresponding debugging
information output to view the debugging information.
Use the display command to view the running information of IP performance and
make sure that the PCs used by the user is running normally.
Use the terminal debugging command to output the debugging information to
the console.
Use the debugging udp packet command to enable the UDP debugging to trace
the UDP packet.
The following are the UDP packet formats:
UDP output packet:
Source IP address:202.38.160.1
Source port:1024
Destination IP Address 202.38.160.1
Destination port: 4296
