Introducing Zoning
Figure 1-1 below illustrates three zones with some overlap. It also contains devices that are not
assigned to a zone, and are thus not active in the fabric if Zoning is enabled.

Implementing Zoning

Implementing Zoning simplifies the zoning process in the following ways:
•
You can administer Zoning from any switch in the fabric. Configuration changes made to one
switch are automatically replicated to all switches in the fabric.
•
Zones can be configured dynamically. When configuring new zones:
•
•
•
Zoning uses policy-based administration. Because Zoning uses policy-based administration —
separating zone specification from zone enforcement — you can manage multiple zone
configurations and easily enable a specific configuration when it is required. A fabric can store
any number of zone configurations; however, only one configuration is active at a time.
Because the configurations are pre-determined and stored, a new configuration can be easily
enabled.
•
Zoning can be configured and administered with either telnet commands or Web Tools.
For information on telnet commands, see the Fabric OS Reference Guide. For information on Web
Tools, see the Web Tools User's Guide.

Fabric with Three Zones
Data traffic on ports and devices is idle for a moment, then resumes according to the new
zoning configuration. With hardware WWN zoning and port zoning, Windows NT ports
may need to be rebooted to access new devices. With HP-UX, a new disc scan may need
to be performed if the zone is altered.
Data traffic across interswitch links (ISLs) in cascaded switch configurations is not
affected.
