alias server

A fabric software facility that supports multicast group management.

API

Application programming interface. A defined protocol that allows applications to

126 devices and one fabric attachment. See also public device, public loop.

AW_TOV

Arbitration wait time-out value. The minimum time an arbitrating L_Port waits for a

 

response before beginning loop initialization.

backup FCS switch Backup fabric configuration server switch. The switch or switches assigned as backup in case the primary FCS switch fails.

bandwidth

The total transmission capacity of a cable, link, or system. Usually measured in bits per

 

second (b/s). May also refer to the range of transmission frequencies available to a

 

link or system.

broadcast

The transmission of data from a single source to all devices in the fabric, regardless of

 

zoning.

buffer-to-buffer flow control

CLI

Management of the frame transmission rate in either a point-to-point topology or an arbitrated loop. See also arbitrated loop, point-to-point, topology.

Command line interface. Interface that depends entirely on the use of commands, such as through telnet or SNMP, and does not involve a GUI.

compact flash

Flash (temporary) memory that is used in a manner similar to hard disk storage. It is

 

connected to a bridging component that connects to the PCI bus of the processor. Not

 

visible within the processor’s memory space.

configuration

The way a system is set up. May refer to hardware or software:

 

• Hardware: The number, type, and arrangement of components that make up a

 

system or network.

 

• Software: The set of parameters that guide switch operation. May include general

 

system parameters, IP address information, domain ID, and other information.

 

Modifiable by any login with administrative privileges. May also refer to a set of

 

zones.

CRC

Cyclic redundancy check. A check for transmission errors that is included in every data

 

frame.

data word
