Chapter 2 ZONING Concepts
Introduction
This chapter includes ZONING components and their definitions.
ZONING Components
ZONING has several components besides the zones. These components include the following:
• zone members
• zone aliases
• zone configurations
Note: These components are generically referred to as zone objects.
Zone Definition
A zone is a set of devices that access one another. All devices connected to a Fabric may be
configured into one or more zones. Devices that are in the same zone can see each other,
devices that are in different zones can not.
Every zone has a name that begins with a letter and followed by any number of letters, digits
and the underscore character (_). Names are case sensitive, for example “Zone_1” and
“zone_1” are different zones.
Note: Spaces are not allowed.
Every zone has a member list, consisting of one or more member (empty zones are not
allowed). See the
“Zone Members” section for more information on member and member list
specifications.
The maximum number of zones and the maximum number of members in a zone are
constrained by memory usage. Since these limits are far larger than the number of devices
connected to a Fabric, they are effectively unlimited.
Zone definitions are persistent. That is the definition remains in effect across reboots and
power cycles until it is deleted or changed.
Note: A device may be a member of multiple zones.
