trace Displays TCP packets coming into or out of the SA8220. It can be
helpful for troubleshooting network problems. Trace accepts a
tcpdump-style expression and several command line options that
cause the device to capture packets in the tcpdump binary format;
You can TFTP this capture to a remote machine for debugging.
Use the CLI file management command to TFTP the resultant
dump file from this device. Any machine with
tcpdump can
decode the binary file into human-readable packet dumps using the
"-r" switch. This command will prompt you for the name of an
output file and a filter file. Press

filter file if you do not have one. It is simply a text file containing
an arbitrarily long tcpdump-style expression which
trace can
use.
