Performance
Fault: IP layer protocol works normally but TCP and UDP cannot work normally.
In the event of such a fault, you can enable the corresponding debugging
information output to view the debugging information.
■ Use the terminal debugging command to output the debugging information
to the console.
■ Use the command debugging udp packet 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
■ Use the debugging tcp packet command to enable the TCP debugging to
trace the TCP packets.
Operations include:
[SW5500]terminal debugging
<SW5500>debugging tcp packet
Then the TCP packets received or sent can be checked in real time. Specific packet
formats include:
TCP output packet:
Source IP address:202.38.160.1
Source port:1024
Destination IP Address 202.38.160.1
Destination port: 4296
Sequence number :4185089
Ack number: 0
Flag :SYN
Packet length :60
Data offset: 10
