This tools shows the Trace file as a sortable table

also you can see a sortable table of MAC addresses, IP addresses and Ports
on eatch table you can find the amount of every MAC/IP/Port that appears at the trace file
To do a trace at 8600 enter the following commands:
| trace clear trace screen off trace level 9 3 wait a minute or two and start to log the session (save the output to log file) trace off trace info |
after that you enter the ‘info’ you will see alot of lines that shows what the CPU was doing at that time

| show sys perf |
