Glossary
10Base-T
10 Mbps, BASEband operation, unshielded Twisted-pair wiring used for Ethernet
networks.
Agent
A node (or software/hardware on a node) that supplies network management
information.
Battery-backed RAM
The probe’s memory that contains a copy of the probe configuration. If power is
removed from the probe (either by unplugging the power cord or from a power
outage), this memory is preserved by power provided by the probe's internal
battery.
Bridge
A device providing an intelligent connection between two otherwise independent
LANs. Bridges operate at layer 2 of the ISO OSI reference model. A bridge
inspects every packet originating on either LAN and creates a table of nodes and
their locations. It isolates the LANs from each other, allowing both sides to pass
traffic internally. If a transmission from one LAN is addressed to a node on the
other LAN, the bridge transmits it onto the other LAN for the destination node.
Broadcast address
The station address FFFFFF-FFFFFF. Packets intended for all nodes on a LAN
use this address as the destination address.
Broadcast packet
A packet sent to all nodes on a LAN.
Collision
The result of two or more nodes on a LAN transmitting at the same time,
producing a garbled transmission.
Console
The ASCII terminal, or PC emulating an ASCII terminal that is connected to the
probe and used to configure, monitor, and troubleshoot the probe.
