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 multi-switch 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 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. Note that the CTP card on this switch is an internal component and not a FRU. 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 back up 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. Glossary-4 edge switch 2/24 product manager user guide
