Collision Domain
Single CSMA/CD LAN segment.
CSMA/CD
Carrier Sense Multiple Access/Collision Detect is the communication
method employed by Ethernet and Fast Ethernet.
Dynamic Host Control Protocol (DHCP)
Provides a framework for passing configuration information to hosts on a
TCP/IP network. DHCP is based on the Bootstrap Protocol (BOOTP),
adding the capability of automatic allocation of reusable network
addresses and additional configuration options.
Extensible Authentication Protocol over LAN (EAPOL)
EAPOL is a client authentication protocol used by this switch to verify the
network access rights for any device that is plugged into the switch. A
user name and password is requested by the switch, and then passed to
an authentication server (e.g., RADIUS) for verification. EAPOL is
implemented as part of the IEEE 802.1x Port Authentication standard.
End Station
A workstation, server, or other device that does not act as a network
interconnection.
Ethernet
A network communication system developed and standardized by DEC,
Intel, and Xerox, using baseband transmission, CSMA/CD access, logical
bus topology, and coaxial cable. The successor IEEE 802.3 standard
provides for integration into the OSI model and extends the physical layer
and media with repeaters and implementations that operate on fiber, thin
coax and twisted-pair cable.
Fast Ethernet
A 100 Mbps network communication system based on Ethernet and the
CSMA/CD access method.
