Brocade Enterprise Fabric Connectivity Manager (EFCM)
Optionally licensed Brocade software that provides easy, centralized
management of a SAN and quick access to all device configuration
applications.
Brocade Web Tools Optionally licensed software component of Fabric OS that enables
administrators to monitor and manage single or small fabrics, switches, and
ports from a standard workstation.
Broadcast zone In Fabric OS 5.3.0 or later, a zone with the name of “broadcast” (case-
sensitive), which is used for setting up recipients of broadcast packets. Does
not restrict access to its members, but restricts broadcast packets to only
those devices that are members.
Buffer-to-buffer flow control
Management of the frame transmission rate in either a point-to-point
topology or in an Arbitrated Loop.
Bypass circuitry Circuits that automatically remove a device from the data path when valid
signals are dropped.
C
CAM Content-Addressable Memory.
Cascade Connecting two or more Fibre Channel hubs or switches to increase port
capacity or distance. Seven levels of cascading is the limit for Brocade
switches. Brocade 1000 switches can have up to 32 in a SAN; Brocade
2000 switches and above can have up to 239.
CDR Clock and Data Recovery circuitry.
CE Conformité Européenne.
Channel A point-to-point link whose task is to transport data from one point to

resources to be managed by a common application.
Class 1 A connection-oriented class of service that requires acknowledgment of
frame delivery.
Class 2 A connectionless class of service that requires acknowledgment of frame
delivery.
Class 3 A connectionless class of service that requires no acknowledgment of frame
delivery between N_Ports.
Class 4 A connection-oriented service that allows fractional parts of the bandwidth to
be used in a virtual circuit.
Class 6 A connection-oriented, multicast service geared toward video broadcasts
between a central server and clients.
