Step 3 Select the protocols, TCP, UDP, or ICMP.
Then, if required, fill in the list of ports to capture for TCP and UDP. The Port(s)
field accepts one or more TCP or UDP ports, separated by a single space. If you
specify port but not the address, it provides an output for that port for all the active
devices.
You can stop a capture cycle after:
•
A certain period time.
•
The filter has captured a certain amount of data.
•
A certain number of packets have been captured.
By default, capture cycles stop after 60 seconds.
Step 4
Click OK.
The Packet Capture dialog box with the new packet capture file added to the list
of the archived capture files is displayed after the capture is performed.
Step 5
Click on the new packet capture file link to get the result.
While the capture is being performed, if you click OK, Packet Capture status
popup appears with the current status of the capture.
If you click Stop Capture in the popup, capture stops and packet capture
information till then is added in the Packet Capture dialogue box, among the
archive files.
The result can be opened in any sniffer application, like Ethereal. These files are
in binary libpcap format with a .jet extension.
You can download these files directly through your web browser, then email them
to the TAC for further analysis.
