Configuring and analyzing packet sniffing

The G450 packet sniffing service allows you to analyze packets that pass through the G450's
interfaces. Packets are captured to a buffer based on criteria that you specify. The buffer is then
uploaded via FTP to a file that can be analyzed using the Ethereal analysis tool.
The packet sniffing service on the G450 offers several advantages to the network administrator.
Since the capture file is saved in the libpcap format, which is the industry standard, it is readable
both by the S8300's Tethereal software, and by standard versions of Ethereal for Unix,
Windows, and Linux (see http://www.ethereal.com).
Note:
Ethereal is an open source application.
Note:
In addition, the G450's packet sniffing service is capable of capturing non-Ethernet packets,
such as frame-relay and PPP. Non-Ethernet packets are wrapped in a dummy Ethernet header
to allow them to be viewed in a libpcap format. Thus, the G450 allows you to analyze packets on
all the interfaces of the device.
