Glossary
configuration data Acollection ofdata that results from configuring director, switch, and
system operating parameters. Configuration data includes product
identification, port configurations, operating parameters, SNMP
configuration, and zoning configuration. A backup file is required to
restore configuration data if the CTP card in a nonredundant director
is removed and replaced.
connectionless A nondedicated link between fabric-attached nodes that allows a
director or switch to forward Class 2 or Class 3 Fibre Channel frames
as resources (ports) allow.
control processor
card
A printed circuit board that provides the microprocessor and control
logic for all directors and switches. The CTP card also initializes
hardware components after system power-on. The board may also
provide an RJ-45 Ethernet connector.
control unit port An internal director or switch port, embedded on the CTP card, that
communicates with channels to report errors and link initialization.
CTP card See control processor card.
CUP See control unit port.
D
DB-9 connector A 9-pin serial connector typethat provides connectivity toan ES-1000
Switch GBIC. Contrast with high speed serial data connector.
default zone A zone that contains all fabric-attached devices not configured as
members of a user-specified zone in the active zone set.
D_ID See destination identifier.
destination identifier A 3-byte field in a Fibre Channel frame header that indicates the
targeted destination (address identifier of the device N_Port) of the
transmitted frame.
director A redundant, highly-available Fibre Channel switch with a high port
countthatprovidesany-to-anyportconnectivitybetweendevices
(nodes) connected to a switched fabric. A director transmits data
frames between nodes in accordance with the address information
provided in the associated frame headers. Directors are well suited
