CFN Change fabric name. 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. CIM is implementation
independent, allowing different management applications to collect the required
data from a variety of sources. CIM is divided into a Core Model and Common
Models. The Core Model addresses high-level concepts (such as systems and
devices), as well as fundamental relationships (such as dependencies). The
Common Models describe specific problem domains such as computer system,
network, user or device management. The Common Models are subclasses of
the Core Model and may also be subclasses of each other.
CIMOM Common Information Model Object Manager. A model for describing
management information from the Distributed Management Task Force (DMTF).
See also CIM.
circuit An established communication path between two ports. Consists of two virtual
circuits capable of transmitting in opposite directions.
Class 1 service The class of frame-switching service for a dedicated connection between
two communicating ports. Also called connection-oriented service. Includes
acknowledgement of frame delivery or nondelivery.
Class 2 service A connectionless class of frame-switching service that includes acknowledgement
of frame delivery or nondelivery.
Class 3 service A connectionless class of frame-switching service that does not include
acknowledgement of frame delivery or nondelivery. Can be used to provide
a multicast connection between the frame originator and recipients, with
acknowledgement of frame delivery or nondelivery.
Class 4 service A connection-oriented service that allows fractional parts of the bandwidth
to be used in a virtual circuit.
Class 6 service A connection-oriented multicast service geared toward video broadcasts
between a central server and clients.
Class F service The class of frame-switching service for a direct connection between two
switches, allowing communication of control traffic between the E_Ports. Includes
acknowledgement of data delivery or nondelivery.
class of service A specified set of delivery characteristics and attributes for frame delivery.
CLI Command line interface. An interface that depends entirely on the use of
commands, such as through telnet or SNMP, and does not involve a GUI.
client An entity that, using its common transport (CT), makes requests of a server.
CLS Close primitive signal. Used only in an arbitrated loop. Sent by an L_Port that is
currently communicating in the loop, to close communication with another L_Port.
CM Central memory. Physical memory that is internal to the computer. Also called
main memory.
CMA Central memory architecture. An architecture centralizing memory usage in
switches.
Central memory built-in self-repair.
