Usage Information Use the tcpdump command to perform a packet capture on a specified switch CPU:
Control Processor (CP) or Route Processor (RP).
You can use the capture-duration timer and the packet-count counter at the same
time. The TCP dump stops when the first of the thresholds is met. That means that
even if the duration timer is 9000 seconds, if the maximum file count parameter is met
first, the dumps stop.
Enclose the filter option with double quotes: "port 20." The
range is 1 to 100 characters.
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.
Enter the number of packets to capture. The counter begins as
soon as the command is enabled. The range is 10 to 150000.
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.
Enter the location to save the captured packets. Files can be
saved to flash, to FTP, SCP, or TFTP:
•
flash://filepath
•
ftp://userid:password@hostip/filepath
•
scp://userid:password@hostip/filepath
•
tftp://hostip/filepath
