Glossary–3
Glossary
class of Fibre Channel service
Defines the level of connection dedication, acknowledgment, and other characteristics of a
connection.
Class F Fibre Channel service
Used by Switches to communicate across interswitch links (ISLs) to configure, control, and
coordinate a multiswitch fabric.
Class 2 Fibre Channel service
Provides a connectionless (not dedicated) service with notification of delivery or nondelivery
between two N_Ports. In-order delivery of frames is not guaranteed.
Class 3 Fibre Channel service
Provides a connectionless (not dedicated) service without notification of delivery or
nondelivery between two N_Ports. Also known as datagram.
community profile
Information that specifies which management objects are available to what management
domain or SNMP community name.
concurrent maintenance
Ability to perform maintenance tasks, such as removal or replacement of field-replaceable
units (FRUs), while normal operations continue without interruption.
See also
nondisruptive
maintenance.
configuration data
Configuration data includes: identification data, port configuration data, operating parameters,
SNMP configuration, and zoning configuration. A configuration backup file is required to
restore configuration data if the control processor (CTP) card in a nonredundant Director is
removed and replaced.
connector
See
optical fiber connector.
connectionless
Nondedicated link. Typically used to describe a link between nodes which allows the Switch to
forward Class 2 or Class 3 frames as resources (ports) allow.
control processor (CTP) card
Circuit card that contains the Director microprocessor. The CTP card also initializes hardware
components of the system after power-on. A 10 Mbps RJ-45 twisted pair connector is located
on the CTP card to connect to an Ethernet LAN and communicate with the HAFM server or a
specific management station.
control unit
A device that controls the reading, writing, or displaying of data at one or more input/output
units.
