tcpdump
Enable a TCP dump for CPU bound traffic.
Syntax
tcpdump cp [capture-duration time | filter expression value | packet-count
value | snap-length value | write-to path]
To disable the TCP dump, use the no tcpdump command.
Parameters
capture-duration
Enter the time for packet capturing. The timer begins as soon as the command is
enabled. The range is 20 to 9000 seconds.
filter
Specify the packet that will be dumped. If no filter is entered, all packets are
dumped. Filter expressions usually consist of an id (name or number) preceded by
one or more qualifiers. There are three different kinds of qualifier: type, direction,
or protocol.
Enclose the filter option with double quotes: port 20. The range is 1 to 100
characters.
packet-count
Enter the number of packets to capture. The counter begins as soon as the
command is enabled. The range is 10 to 150000.
