Trace The trace command captures traffic on a network that matches the
given expression. The trace output can be helpful for
troubleshooting network problems.
NOTE: By default,
trace will automatically
exit after 60 seconds. If
the GUI is configured for
a shorter timeout, the
trace information may
be lost. For more details,
please see “GUI Tab” in
this chapter.
Syntax:
trace [-aefnNpqStvxX] [-c <count>]
[-i <interface>] [-s <snaplen>] [-T <type>]
-F <file> [-P] -w <file> -H <tftp-host>
-D <tftp-path>
Switches enclosed in brackets [] are optional. The -w, -F, -H, and -D
switches are required. A complete listing of the switches for the
trace command is found in the following table.
Example:
The command below TFTPs my.filter from dhcp8/var/
tftpboot/my.filter to the SA8220, captures five packets
(using the expressions in the my.filter file), and then writes the
packet information to the fred.dump file. Because of the -P switch,
the filter file is not deleted.
trace -c 5 -w fred.dump -F my.filter -H dhcp8
-D /var/tftpboot -P
If the -P switch is not used, the filter file is deleted.
