3.4.1.1

Zones

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

3.4.1.1.1

Soft Zones

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.
