Q

The following zoning concepts provide some context for the zoning tasks 
described in this section:

„

Zones

Aliases

Zone sets

Zoning configuration

A zone is a named group of ports or devices that can communicate with each 
other. Membership in a zone can be defined by domain ID and port number, 
device Fibre Channel address, or device World Wide Name (WWN). Zone 
members can communicate only with members of the same zone.

Three types of zones are supported. The following zone types define increasingly 
restrictive levels of communication.

„

Soft zone

„

Access Control List (ACL) - hard zone

„

Virtual Private Fabric (VPF) - hard zone

Soft zoning divides the fabric for purposes of controlling discovery. Members of 
the same soft zone automatically discover and communicate freely with all other 
members of the same zone. The soft zone boundary is not secure; traffic across 
soft zones can occur if addressed correctly. Soft zones that include members from 
multiple switches need not include the ports of the inter-switch links. Soft zone 
boundaries yield to ACL and VPF zone boundaries. Soft zones can overlap; that 
is, a port can be a member of more than one soft zone. Zone membership can be 
defined by Fibre Channel address, domain ID and port number, worldwide name, 
or a combination. Soft zoning supports all port modes.
