3.2 Displaying and Debugging IP Performance
After the above IP performance configuration, you can execute the
display
commands
in any view to display the system operating status and thus verify the IP performance
configuration.
You can execute the
reset
commands in user view to clear the IP, TCP and UDP traffic
statistics. You can also execute the
debugging
commands to enable different IP
performance debugging.
