3Com Network The 3Com network management application used to manage 3Com's
Supervisor networking solutions.
10BASE-T The IEEE specification for 10 Mbps Ethernet over Category 3, 4 or 5
twisted pair cable.
100BASE-FX The IEEE specification for 100 Mbps Fast Ethernet over fiber-optic cable.
100BASE-TX The IEEE specification for 100 Mbps Fast Ethernet over Category 5
twisted-pair cable.
1000BASE-T The IEEE specification for 1000 Mbps Gigabit Ethernet over four-pair
Category 5 twisted-pair cable.
1000BASE-SX The IEEE specification for 1000 Mbps Gigabit Ethernet over fiber-optic
cable.
Access Control List A permission system used to restrict access to a resource. An ACL
(ACL) comprises a list of authorized users.
aging The automatic removal of dynamic entries from the Switch Database
which have timed-out and are no longer valid.
Aggregated Links Aggregated links allow a user to increase the bandwidth and resilience
between switches by using a group of ports to carry traffic between
the switches.
auto-negotiation A feature on twisted pair ports that allows them to advertise their
capabilities for speed, duplex and flow control. When connected to a
port that also supports auto-negotiation, the link can automatically
configure itself to the optimum setup.
backbone The part of a network used as a primary path for transporting traffic
between network segments.
