 * ["Ethernet"]: Typically, LLC uses ["Ethernet"] as its transport protocol. LLC can use a number of LAN (and MAN/WAN?) protocols as its transport protocol:

 * ["Ethernet"]: LLC can be used for packets on ["Ethernet"] networks, although many protocols don't use it when running atop Ethernet.
 * ["IEEE 802.11"]: LLC is used for data packets on ["IEEE 802.11"] networks.

Logical Link Control (LLC, IEEE 802.2)

XXX - add a brief LLC description here

History

XXX - add a brief description of LLC history

Protocol dependencies

LLC can use a number of LAN (and MAN/WAN?) protocols as its transport protocol:

  • ["Ethernet"]: LLC can be used for packets on ["Ethernet"] networks, although many protocols don't use it when running atop Ethernet.
  • ["IEEE 802.11"]: LLC is used for data packets on ["IEEE 802.11"] networks.
  • ["FDDI"]: LLC is used for data packets on ["FDDI"] networks.
  • TokenRing: LLC is used for data packets on TokenRing networks.

Example traffic

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

Ethereal

The LLC dissector is (XXX - fully functional, partially functional, not existing, ... whatever the current state is).

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. 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 LLC display filter fields can be found in the [http://www.ethereal.com/docs/dfref/l/llc.html display filter reference]

  • Show only the LLC based traffic:

     llc 

Capture Filter

XXX - add info how LLC can be filtered

  • add link to LLC specification and where to find additional info on the web about LLC
