Boot Monitor
Code used to initialize the CP (control processor) environment after powering on. Identifies the
amount of memory available and how to access it, and retrieves information about system buses.
Broadcast
The transmission of data from a single source to all devices in the fabric, regardless of zoning.
See also
multicast, unicast.
Buffer

to
-
buffer Flow Control
Management of the frame transmission rate in either a point-to-point topology or in an arbitrated
loop.
See also
BB_Credit.
Cascade
Two or more interconnected Fibre Channel switches. StorageWorks 1 Gb SAN switches (running
Fabric OS V2) and later can be cascaded up to 239 switches, with a recommended maximum of
seven interswitch links (no path longer than eight switches).
See also
fabric, ISL.
Chassis
The metal frame in which the switch and switch components are mounted.
Circuit
An established communication path between two ports. Consists of two virtual circuits capable of
transmitting in opposite directions.
See also

Class 1
Service that provides a dedicated connection between two ports (also called connection-oriented
service), with notification of delivery or non-delivery.
Class 2
Service that provides multiplex and connectionless frame switching service between two ports,
with notification of delivery or non-delivery.
Class 3
Service that provides a connectionless frame switching service between two ports, without
notification of delivery or non-delivery of data. This service can also be used to provide a multicast
connection between the originator and recipients, with notification of delivery or non-delivery.
