Glossary 1000BASE-T - 1000BASE-T - Known as IEEE 802.3ab which is a standard for Gigabit Ethernet over copper wiring. 100BASE-TX - 100Mbps Ethernet implementation over Category 5 and Type 1 T wisted Pair cabling. 10BASE-T - The IEEE 802.3 specification for Ethernet over Unshielded T wisted Pair (UTP) cabling. Aging - The automatic removal of dynamic entries from the Switch Database which have timed-out and are no longer valid. ATM - Asynchronous Transfer Mode. A connection oriented transmission protocol based on fixed length cells (packets). ATM is designed to carry a complete range of user traffic, including voice, data, and video signals. Auto-Negotiation - A feature on a port, which allows it to advertise its capabilities for speed, duplex, and flow control. When connected to an end station that also supports auto-negotiation, the link can self-detect its optimum operating setup. Backbone port - A port that does not learn device addresses, and that receives all frames with an unknown address. Backbone ports are normally used to connect the Switch to the backbone of your network. Note that backbone ports were formerly known as designated downlink ports. Backbone - The part of a network used as the primary path for transporting traffic between network segments. Ban dwi dth - Informat ion capacity, measured in bit s per second, that a channel can transmit. The bandwidth of Ethernet is 10Mbps. the bandwidth of Fast Ethernet is 100Mbps. Baud Rate - The switching speed of a line. Also known as line speed. BOO TP - The BOOTP protocol allows you to automatically map an IP address to a given MAC address each time a device is started. In addition, the protocol can assign the subnet mask and default gateway to a device. Bridge - A device that interconnects local or remote networks no matter what higher level protocols are involved. Bridges form a single logical network, centralizing network admin istrat io n. Broadcast - A message sent to all dest inat ion devices on the net work. Broadcast Storm - Multiple simultaneous broadcasts that typically absorb available network bandwidth and can cause network failure. 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 t ransmission links. This port is most oft en used for dedicat ed local management . CSMA/C D - 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. 31
