3DES
A three-round application of the Data Encryption Standard (DES) that uses a 168-bit encryption
key. See also DES.
802.1D
The IEEE LAN specication for the operation of media access control (MAC) bridges.
802.1p
An IEEE LAN standard method for classifying packets in bridged virtual LANs (VLANs). As
part of 802.1Q protocol, 802.1p denes a eld in the VLAN tag of a frame header that provides
class-of-service (CoS) denitions at Layer 2. See also 802.1Q.
802.1Q
The IEEE LAN standard that denes a protocol for ltering and forwarding services at
Layer 2. Ethernet frames are directed by means of a tag inserted into the frame header. A
virtual LAN (VLAN) identier (VID) eld in the tag identies the VLAN with which the frame is
associated.
802.1X
The primary IEEE standard for port-based network access control. The 802.1X standard,
which is based on the Extensible Authentication Protocol (EAP), provides an authentication
framework that supports a variety of methods for authenticating and authorizing network
access for wired or wireless users. See also EAP; EAPTLS; PEAP; TLS; TTLS.
802.2
An IEEE LAN specication that denes the logical link control (LLC) sublayer, the upper portion
of the Data Link layer. LLC encapsulation can be used by any lower-layer LAN technology.
Compare 802.3; Ethernet II.
802.3
An IEEE LAN specication for a Carrier Sense Multiple Access with Collision Detection
(CSMA-CD) network, a type of network related to Ethernet. In general, 802.3 species the
physical media and the working characteristics of LANs. An 802.3 frame uses source and
destination media access control (MAC) addresses to identify its originator and receiver (or
receivers). Compare 802.2; Ethernet II.
802.3z
An extension to the IEEE 802.3 LAN specication, describing gigabit Ethernet (1000 Mbps)
transmission. The extension includes specications for the media access control (MAC),
physical layer, repeater, and management characteristics of gigabit Ethernet.
