134 CHAPTER 16: IP PERFORMANCE CONFIGURATIONUse the reset command in user view to clear the IP, TCP, and UDP traffic statistics.Troubleshooting Symptom: IP packets are forwarded normally, but TCP and UDP cannot worknormally.Solution: Enable the corresponding debugging information output to view thedebugging information.■ Use the display command to display the IP performance and check whetherthe PC runs normally.■ Use the terminal debugging command to enable debugging information tobe output to the console.■ Use the debugging udp packet command to enable the UDP debugging totrace UDP packets. terminal debugging debugging udp packetThe UDP packets are shown in the following format:UDP output packet:Source IP address:202.38.160.1Source port:1024Destination IP Address 202.38.160.1Destination port: 4296■ Use the debugging tcp packet command to enable the TCP debugging totrace TCP packets. terminal debugging debugging tcp packetTable 81 Display IP performanceOperation Command DescriptionDisplay TCP connection status display tcp status You can execute thedisplay command inany view.Display TCP connectionstatisticsdisplay tcp statisticsDisplay UDP traffic statistics display udp statisticsDisplay IP traffic statistics display ip statisticsDisplay ICMP traffic statistics display icmp statisticsDisplay the current socketinformation of the systemdisplay ip socket [ socktypesock-type ] [ task-id socket-id ]Display the summary of theforwarding information base(FIB) entry matching thespecified ruledisplay fib fib-ruleTable 82 Debug IP performanceConfiguration Command DescriptionClear IP traffic statistics reset ip statistics The reset commandcan be executed inuser viewClear TCP traffic statistics reset tcp statisticsClear UDP traffic statistics reset udp statistics
