ENGLISH Glossary 1000BASE-LX A short laser wavelength on multimode fiber optic cable for a maximum length of 550 meters. 1000BASE-SX A long wavelength for a "long haul" fiber optic cable for a maximum length of 10 kilometers. 100BASE-FX 100Mbps Ethernet implementation over fiber. 100BASE-TX 100Mbps Ethernet implementation over Category 5 and Type 1 Twisted Pair cabling. 10BASE-T The IEEE 802.3 specification for Ethernet over Unshielded Twisted 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 Aging The automatic removal of dynamic entries from the Switch Database which have timed-out and are no longer valid.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. 20
