Glossary
alias
A logical grouping of elements in a fabric. An alias is a collection of port numbers and connected devices,
used to simplify the entry of port numbers and WWNs when creating zones.
area number
In Fabric OS 4.0 and later, ports on a switch are assigned a logical area number. Port area numbers can
be viewed by issuing the switchShow command. They are used to define the operative port for many
Fabric OS commands, for example, area numbers can be used to define the ports within an alias or zone.
ASIC
Application-specific integrated circuit.
authentication
The process of verifying that an entity in a fabric (such as a switch) is what it claims to be.
backbone fabric
An optional capability that enables scalable meta-SANs by allowing the networking of multiple FC routers,
which connect to the backbone fabric through EB_Port interfaces.
BB_Credit
Buffer-to-buffer credit. The number of frames that can be transmitted to a directly connected recipient or
within an arbitrated loop. Determined by the number of receive buffers available.
beacon
A tool in which all the port LEDs on a switch are set to flash from one side of the switch to the other, to
enable identification of an individual switch in a large fabric. A switch can be set to beacon by a CLI
command or through Advanced Web Tools.
CHAP
Challenge-Handshake Authentication Protocol. Allows remote servers and clients to securely exchange
authentication credentials. Both the server and client are configured with the same shared secret.
chassis
The metal frame in which the switch and switch components are mounted.
circuit
An established communication path between two ports. Consists of two virtual circuits capable of
transmitting in opposite directions.
CLI
Command line interface. An interface that depends entirely on the use of commands, such as through
telnet or SNMP, and does not involve a GUI.
client
An entity that, using its common transport (CT), makes requests of a server.
community (SNMP)
A relationship between a group of SNMP managers and an SNMP agent, in which authentication, access
control, and proxy characteristics are defined. See also SNMP.
