1000BASE-SX
The IEEE specification for 1000 Mbps Gigabit Ethernet over fiber-optic cable.

A
Address Resolution Protocol
An Internet Protocol that dynamically maps Internet addresses to physical (hardware) addresses on a LAN.
Advanced Network Device Layer/Software
Term for the Device Driver level.
Aging
When an entry for a node is added to the lookup table of a switch, it is given a timestamp. Each time a packet
is received from a node, the timestamp is updated. The switch has a user-configurable timer that erases the
entry after a certain length of time with no activity from that node.
Area Border Router
A router located on the border of one or more OSPF areas that connects those areas to the backbone
network. ABRs are considered members of both the OSPF backbone and the attached areas. They therefore
maintain routing tables describing both the backbone topology and the topology of the other areas. (Cisco
Systems Inc.)
ARP
See "Address Resolution Protocol" on page 2.
Auto-negotiation
A feature that allows twisted-pair ports 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.
Auto Uplink
Auto Uplink TM technology (also called MDI/MDIX) eliminates the need to worry about crossover vs.
straight-through Ethernet cables. Auto Uplink TM will accommodate either type of cable to make the right
connection.
