Usage
Use the tcpdump command to perform a packet capture on a specified Z95000
Information
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.
The files saved on the flash are located in the flash://TCP_DUMP_DIR/
Tcpdump_<time_stamp_dir>/directory. The file name is tcpdump_*.pcap. There
can be up to 20 Tcpdump_<time_stamp_dir> directories. If more than 20 files are
created, the oldest is overwritten.
Entering the no tcpdump command stops any TCP dump process running in
either the Control Processor or Route Processor. The dump stops immediately,
without waiting for a threshold to be met.
To stop the TCP dump process running in the CP processor, enter the no
tcpdump cp command; to stop the TCP dump process running in the RP
processor, enter the no tcpdump rp command.
