Linux cooked-mode capture (SLL)

This is the pseudo protocol linux uses to capture from the "any" device.

When capturing from the "any" device in linux, the system won't save the real "hardware protocol" like ["Ethernet"], but this pseudo protocol instead.

XXX - BTW: Why is the abbreviation SLL?


XXX - add a brief description of SLL history

Protocol dependencies

Example traffic

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


The LLC dissector is (fully functional, partially functional, not existing, ... whatever the current state is). Also add info of additional Ethereal features where appropriate, like special statistics of this protocol.

Preference Settings

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

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here (see below). Keep this file 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 LLC display filter fields can be found in the [ display filter reference]

Capture Filter

You cannot directly filter LLC protocols while capturing.
