IBM 4986B LanProbe manual Glossary, 10Base-T, Agent, Battery-backed RAM, Bridge, Broadcast address

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.
