Ethernet (IEEE802 ...)

Ethernet is the most common local area networking technology, and, with gigabit and 10 gigabit Ethernet, is also being used for metropolitan-area and wide-area networking.

It is specified by [http://standards.ieee.org/getieee802/802.3.html various IEEE 802.3 specifications].

History

XXX - add a brief description of Ethernet history

Protocol dependencies

  • Ethernet is the lowest software layer, so it only depends on hardware.

Example traffic

XXX - Add example traffic here (as plain text or Ethereal screenshot).

Ethereal

The Ethernet dissector is fully functional.

Preference Settings

(XXX add links to preference settings affecting how Ethernet is dissected).

Example capture file

XXX - Add a simple example capture file. Keep it short, it's also a good idea to gzip it to make it even smaller, as Ethereal can open gzipped files automatically.

Display Filter

A complete list of Ethernet display filter fields can be found in the [http://www.ethereal.com/docs/dfref/e/eth.html display filter reference]

  • Show only the Ethernet-based traffic:

     eth 

    Show only the Ethernet-based traffic to and from Ethernet MAC address 08:00:08:15:ca:fe:

     eth.addr==08.00.08.15.ca.fe 

Capture Filter

  • Capture only the Ethernet-based traffic to and from Ethernet MAC address 08:00:08:15:ca:fe:

     ether host 08:00:08:15:ca:fe
