console port The port on the Switch accepting a terminal or modem connector. It
changes the parallel arrangement of data within computers to the serial
form used on data transmission links. This port is most often used for
dedicated local management.
CSMA/CD Carrier-sense Multiple Access with Collision Detect. Channel access
method used by Ethernet and IEEE 802.3 standards in which devices
transmit only after finding the data channel clear for some period of
time. When two devices transmit simultaneously, a collision occurs and
the colliding devices delay their retransmissions for a random amount
of time.
data center switching The point of aggregation within a corporate network where a switch
provides high-performance access to server farms, a high-speed
backbone connection and a control point for network management
and security.
Ethernet A LAN specification developed jointly by Xerox, Intel and Digital
Equipment Corporation. Ethernet networks operate at 10 Mbps using
CSMA/CD to run over cabling.
Fast Ethernet 100 Mbps technology based on the Ethernet/CD network access
method.
forwarding The process of sending a packet toward its destination by an
internetworking device.
full duplex A system that allows packets to be transmitted and received at the
same time and, in effect, doubles the potential throughput of a link.
half duplex A system that allows packets to be transmitted and received, but not at
the same time. Contrast with full duplex.
IFM Intelligent Flow Management. A means of holding packets back at the
transmit port of the connected endstation. Prevents packet loss at a
congested switch port.
Intelligent Switching A packet forwarding mode, where the Switch monitors the amount of
Mode error traffic on the network and changes the method of packet
forwarding accordingly.
IPX Internetwork Packet Exchange. A protocol allowing communication in a
NetWare network.
IP address Internet Protocol address. A unique identifier for a device attached to a
network using TCP/IP. The address is written as four octets separated
