secure; traffic across soft zones can occur if addressed correctly. The following 
rules apply to soft zones:

•

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 port can be a member of more than one 
soft zone.

•

Membership can be defined by Fibre Channel address, domain ID and 
port number, or port worldwide name.

•

Soft zoning supports FL_Ports and F_Ports.

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. 
Members can communicate with each other and transmit outside the ACL 
zone, but cannot receive inbound traffic from outside the zone. The following 
rules apply to ACL zones:

•

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. A 
switch module port can be a member of multiple ACL zones whose 
combined membership does not exceed 64.
