Zoning a Fabric

FCID entries define zone membership by the Fibre Channel address of the
attached device. With this membership method you can replace a device on
the same port without having to edit the member entry as you would with a
WWN member.
Domain ID/Port number entries define zone membership by switch domain
ID and port number. All devices attached to the specified port become
members of the zone. The specified port must be an F_Port or an FL_Port.
Two types of zones are supported. The following zone types define increasingly
restrictive levels of communication.
Soft zone
Hard zone - Access Control List (ACL)
3.4.1.1.1
Soft Zones
Soft zoning divides the fabric for purposes of controlling discovery. Devices within
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 zone boundaries. Soft zones can overlap; that is, a
device can participate in more than one soft zone. Zone membership can be
defined by Fibre Channel address, domain ID and port number, World Wide
Name, or a combination. Soft zoning supports all port types.
3.4.1.1.2
Access Control List Hard Zones
Access Control List (ACL) zoning divides the fabric for purposes of controlling
discovery and inbound traffic. ACL zoning is a type of hard zoning that is
hardware enforced. This type of zoning is useful for controlling access to certain
devices without totally isolating them from the fabric. Devices can communicate
with each other and transmit outside the ACL zone, but cannot receive inbound
traffic from outside the zone. The ACL zone boundary is secure against inbound
traffic. ACL zones can overlap; that is, a port can be a member of more than one
ACL zone. ACL zones that include members from multiple switches need not
include the ports of the inter-switch links. ACL zone boundaries supersede soft
zone boundaries. Membership can be defined only by domain ID and port
number. ACL zoning supports all port types.
