Brocade MSRS See MSRS.
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.
bypass
circuitry
Circuits that automatically remove a device from the data path when valid signals are dropped.
C
CA Certificate authority. A trusted organization that issues digital certificates. See also digital certificate.
CAM Content-addressable memory.
CAN Campus area network. A network comprising a limited area but not just one building. See also LAN,
MAN, WAN.
cascade Two or more interconnected Fibre Channel switches. Brocade SilkWorm 2000 and later switches 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.
CDR Clock and data recovery circuitry.
CE Conformité Européenne.
CFG Configuration.
CFN Change fabric name. Refers to an ELS field that appears in portlogdump command output.
CHAP Challenge-Handshake Authentication Protocol. Allows remote servers and clients to securely exchange
authentication credentials. Both the server and client are configured with the same shared secret.
chassis The metal frame in which the switch and switch components are mounted.
CIM Common Information Model. A management structure enabling disparate resources to be managed by a
common application.
CIMOM Common Information Model Object Manager. A model for describing management information from
the DMTF. CIM is implementation independent, allowing different management applications to collect
the required data from a variety of sources. CIM includes schemas for systems, networks, applications
and devices, and new schemas will be added. It also provides mapping techniques for interchange of
CIM data with MIB data from SNMP agents and MIF data from DMI-compliant systems.
circuit An established communication path between two ports. Consists of two virtual circuits capable of
transmitting in opposite directions.
