Glossary
1000BASE-LX
A short laser wavelength on multimode ber optic cable for a maximum length of 550 meters.
1000BASE-SX
Alongwavelengthfora“longhaul”beropticcableforamaximumlengthof10kilometers.
100BASE-FX
100Mbps Ethernet implementation over ber.
100BASE-TX
100Mbps Ethernet implementation over Category 5 and Type 1 Twisted Pair cabling.
10BASE-T
The IEEE 802.3 specication 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The automatic removal of dynamic entries from the Switch Database which have timed-out and are no longer valid.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 xed length cells (packets). ATM is designed to carry a complete
range of user trac, including voice, data, and video signals.
Auto-Negotiation
A feature on a port, which allows it to advertise its capabilities for speed, duplex, and ow 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 trac between network segments.
