Auto-negotiation

Allows 10/100 Mpbs or 10/100/1000 Mbps Ethernet ports to establish for the following features:

Duplex/ Half Duplex mode

Flow Control

Speed

B

Back Pressure

A mechanism used with Half Duplex mode that enables a port not to receive a message.

Backplane

The main BUS that carries information in the switch module.

Backup Configuration Files

Contains a backup copy of the switch module configuration. The Backup file changes when the Running Configuration file or the Startup configuration file is copied to the Backup file.

Bandwidth

Bandwidth specifies the amount of data that can be transmitted in a fixed amount of time. For digital switch modules, bandwidth is defined in Bits per Second (bps) or Bytes per Second.

Bandwidth Assignments

The amount of bandwidth assigned to a specific application, user, or interface.

Baud

The number of signaling elements transmitted each second.

Best Effort

Traffic is assigned to the lowest priority queue, and packet delivery is not guaranteed.

Boot Version

The boot version.

BootP

Bootstrap Protocol. Enables a workstation to discover its IP address, an IP address of a BootP server on a network, or a configuration file loaded into the boot of a switch module.

BPDU

Bridge Protocol Data Unit. Provide bridging information in a message format. BPDUs are sent across switch module information with in Spanning Tree configuration. BPDU packets contain information on ports, addresses, priorities, and forwarding costs.
