|
agent. The interface to a managed device
|
alias server. A fabric software facility that supports multicast group management.
|
AL_PA. Arbitrated Loop Physical Address. An 8-bit value used to uniquely identify an individual port within a loop. A
|
loop may have one or multiple AL_PAs.
|
ANSI. American National Standards Institute.
|
arbitrated loop. The FC arbitrated loop (FC-AL) is a standard defined on top of the FC_PH) standard. It defines the
|
arbitration on a loop where several FC nodes share a common medium.
|
ASIC. Application specific integrated circuit.
|
asynchronous transfer mode. A broadband technology for transmitting data over LANs or WANs, based on relaying
|
cells of fixed size. Provides any-to-any connectivity, and nodes can transmit simultaneously.
|
ATM. See asynchronous transfer mode .
|
BIOS. Basic input and output system.
|
BISR. Built-in self-repair.
|
BTU. British thermal unit.
|
CAM. Content addressable memory.
|
cascading switches. Switches that are interconnected to build large fabrics.
|
class 2. In class 2 service, the fabric and destination N_port provide connectionless service with notification of
|
delivery or nondelivery between the two N_ports.
|
class 3. Class 3 service provides a connectionless service without notification of delivery between N_ports. The
|
transmission and routing of class 3 frames is the same as for class 2 frames.
|
class F. A class of service used for interswitch control traffic. It provides connectionless service with notification of
|
delivery or nondelivery between two E_ports.
|
community (SNMP). An SNMP community is a relationship between an SNMP agent and a set of SNMP managers
|
that defines authentication, access control, and proxy characteristics.
|
COS. Class of service.
|
CPU. Central processing unit.
|
credit. Credit, when applied to a switch, is the numeric value that represents the maximum number of receive buffers
|
provided by an F_port or FL_port to its attached N_port or NL_port respectively such that the N_port or NL_port may
|
transmit frames without over-running the F_port or NL_port.
|
daemon. In the AIX operating system, a program that runs unattended to perform a standard service. Some
|
daemons are triggered automatically to perform their task; other operate periodically. Synonymous with demon.
|
defined configuration. The complete set of all zone objects that are defined in the fabric. The defined configuration
|
may include multiple zone configurations.
|
domain_ID. The domain number uniquely identifies the switch in a fabric. This switch domain ID is normally
|
automatically assigned by the switch and may be any value between 0 - 31. This number can also be assigned
|
manually.
