tcpdump
Enable a TCP dump for CPU-bound traffic on the Control and Router Processors..
C9000 Series
Syntax
tcpdump {cp | rp} [capture-duration time | filter expression | max-file-count
value | packet-count value | snap-length value | write-to path]
To disable the TCP dump, use the no tcpdump command.
Parameters
cp Enter the keyword cp to perform a dump on traffic processed by the Control Processor
CPU.
rp Enter the keyword rp to perform a dump on traffic processed by the Route Processor
CPU.
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 num ber) 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.
max-file-count Enter the maximum number of 1MB files. The maximum file size for a TCP dump capture
is 1MB. When a file reaches 1MB, a new file is created, up to the specified number. The
range is 1 to 20.
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.
snap-length Enter the number of bytes per packet to capture. Use this option to reduce the size of
the captured packets, to capture only the needed headers and avoid rest of the data
portion of the packet. The range is 0 to 1200.
write-to Enter the location to save the captured packets. Files can be saved to flash, to FTP, SCP,
or TFTP:
