Configuring and analyzing packet sniffing

The G250/G350 packet sniffing service allows you to analyze packets that pass through the
G250/G350'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 G250/G350 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 t-ethereal 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 G250/G350'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 G250/G350 allows you to
analyze packets on all the interfaces of the device.
