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 a datagram.
CMM
See central memory module card.
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, while a hardware product is operating. 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 nonredundant CTP card in a Director is removed and replaced.
connectionless
Nondedicated link. Typically used to describe a link between nodes which allows the Switch to
forward Class 2 or Class 3 frames as 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
Also known as CTP. 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 the Ethernet LAN and communicate with
the HAFM server or a specific management station.
CRC
See cyclic redundancy check.
CTP
See control processor card.
