Packet sniffing
The Branch Gateway packet sniffing service allows you to analyze packets that pass through
the Branch Gateway’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 Branch Gateway 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.
In addition, the Branch Gateway’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 Branch Gateway
allows you to analyze packets on all the interfaces of the device.
The Branch Gateway’s packet sniffing service gives you full control over the memory usage of
the sniffer. You can set a maximum limit for the capture buffer size, configure a circular buffer
