Glossary
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 firmware
upgrade
The CTP card provides two nonvolatile memory regions. Because
two firmware versions can be stored on the card, firmware is
upgraded without disrupting switch operation.
concurrent
maintenance
Ability to perform maintenance tasks, such as removal or
replacement of field-replaceable units, while a hardware product is
operating.
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 CTP card in a nonredundant switch or
switch is removed and replaced.
configuration report An ASCII text file containing all current user-definable configuration
options.
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. Contrast this to the dedicated bandwidth that
is required in a Class 1 Fibre Channel Service point-to-point link.
connector See optical fiber connector.
control processor
card
Circuit card that contains the switch 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 the Ethernet LAN and communicate with the EFC Server
or a specific management station.
control unit A hardware unit that controls the reading, writing, or displaying of
data at one or more input/output units.
