Glossary

Active zone set

The zone set that defines the current zoning for the fabric

Active firmware

The firmware image on the switch that is in use

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 Command Line

Interface (CLI).

Alarm

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

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

Alias

A named set of ports or devices. An alias is not a zone, and can not have a zone or

another alias as a member.

AL_PA

Arbitrated Loop Physical Address

Arbitrated loop

An FC topology where ports use arbitration to establish a point-to-point circuit

Arbitrated Loop

Physical Address

(AL_PA)

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

loop

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 which multiplexes frames at frame boundaries to or from one or more

N_Ports wit h acknowledgment provided

Class 3 service

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

N_Ports without acknowledgment

Default Visibility

Zoning parameter that determines the level of communication among ports/devices

when there is no active zone set. It is recommended that all switches have the same

Default Visibility setting.

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

Discard Inactive

A zoning configuration parameter that automatically removes the previously active

zone set when a zone set is activated on a switch (non-configurable, always

enabled)

Configured zone sets The zone sets stored on a switch excluding the active zone set
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

must have the same value throughout the fabric. If interop mode is McDATA Fabric

Mode, the Default Zone parameter is automatically distributed throughout the

fabric. If McDATA 4Gb SAN Switches are in a fabric with other M-Series directors

and edge switches, and the interop mode is Standard/Open Fabric, the Default

Zone parameter MUST be disabled (False) on the McDATA 4Gb SAN Switches for

zoning to function properly.
