Configuring and analyzing packet sniffing
Issue 5 June 2008 459
Analyzing captured packets
Analyze the captured packets by stopping the packet sniffing service, uploading the capture file,
and analyzing the capture file.
Stopping the packet sniffing service
Enter
capture stop
to stop the packet sniffing service. You must stop the service in order to
upload a capture file.
Note:
Note:
The
capture stop
command is not saved in the startup configuration file.
Viewing packet sniffing information
You can enter
show capture

Note:
The number of captured frames can be larger than the number of the frames in
the buffer because the capture file may be in cyclic mode.
You can use the
show capture-buffer hex
command to view a hex dump of the captured
packets. However, for a proper analysis of the captured packets, you should upload the capture
file and analyze it using a sniffer application, as described in the following sections.
