Glossary

Active firmware

The firmware image on the switch that is in use

Active zone set

The zone set that defines the current zoning for the fabric

Activity LED

A port LED that indicates when frames are entering or leaving the port

Administrative state

State that determines the operating state of the port, I/O blade, or switch. The

 

configured administrative state is stored in the switch configuration. The configured

 

administrative state can be temporarily overridden using the CLI.

AL_PA

Arbitrated Loop Physical Address

Alarm

A message generated by the switch that specifically requests attention. Alarms are

 

generated by several switch processes. Some alarms can be configured.

Arbitrated loop

An Fibre Channel topology where ports use arbitration to establish a point-to-point

 

circuit

Arbitrated Loop

A unique one-byte value assigned during loop initialization to each NL_Port on a

Physical Address

loop

(AL_PA)

 

ASIC

Application Specific Integrated Circuit

Auto Save

Zoning parameter that determines whether changes to the active zone set that a

 

switch receives from other switches in the fabric will be saved to permanent memory

 

on that switch

BootP

A type of network server

Buffer credit

A measure of port buffer capacity equal to one frame

Cascade topology

A fabric in which the switches are connected in series. If you connect the last switch

 

back to the first switch, you create a cascade-with-a-loop topology.

CHAP

Challenge Handshake Authentication Protocol

Class 2 service

A service that multiplexes frames at frame boundaries to or from one or more

 

N_Ports wit h acknowledgment provided

Class 3 service

A service that multiplexes frames at frame boundaries to or from one or more

 

N_Ports without acknowledgment

Configured zone sets The zone sets stored on a switch.

DefaultZone

Enables (True) or disables (False) communication among ports/devices that are not

 

defined in the active zone set or when there is no active zone set. This parameter

 

applies only when interop mode is set to McDATA Fabric Mode.

Device Security

A component of fabric security that provides for the authorization and

 

authentication of devices that attach to a switch through the use of groups and

 

security sets

Domain ID

User defined number that identifies the switch in the fabric

EFCM

Enterprise Fabric Connectivity Manager

Element Manager

Switch management application that is accessible through the High Availability

 

Fabric Manager (HAFM).

Event log

Log of messages describing events that occur in the fabric

Expansion port

E_Port that connects to another FC-SW-2 compliant switch

Fabric database

The set of fabrics that have been opened during a McDATA Web Server session

Fabric management

The switch through which the fabric is managed (the switch connected to the

switch

Ethernet network)

Fabric name

User defined name associated with the file that contains user list data for the fabric

Fabric port

An F_Port
