1000BASE-T
A specification for Gigabit Ethernet over copper (IEEE 802.3ab). The standard defines 1 Gbps data transfer over
distances of up to 100 meters using 4 pairs of CAT-5 balanced copper cabling and a 5-level coding scheme. Its benefits
include compatibility with existing network protocols (i.e. IP, IPX, AppleTalk), existing applications, Network Operating
Systems, network management platforms and applications.
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The automatic removal of dynamic entries from the Switch Database which have timed-out and are no longer valid.
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.
