3.7.1.1.2
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. You can have domain/port member in 
a configured ACL zone, but it will be converted to a soft zone when activated.
3.7.1.2
Aliases
To make it easier to add a group of ports or devices to one or more zones, you can 
create an alias. An alias is a named set of ports or devices that are grouped 
together for convenience. Unlike zones, aliases impose no communication 
restrictions between its members. You can add an alias to one or more zones. 
However, you cannot add a zone to an alias, nor can an alias be a member of 
another alias.
3.7.1.3
Zone Sets
A zone set is a named group of zones. A zone can be a member of more than one 
zone set. Each switch in the fabric maintains its own zoning database containing 
one or more zone sets. This zoning database resides in non-volatile or permanent 
memory and is therefore retained after a reset. Refer to 
 for information about displaying the zoning database.
The orphan zone set is created by the application automatically to hold the zones 
which are not in any set. The orphan zone set cannot be removed and is not 
saved on the switch.
To apply zoning to a fabric, choose a zone set and activate it. When you activate a 
zone set, the switch distributes that zone set and its zones, excluding aliases, to 
every switch in the fabric. (However, the contents of the aliases are distributed.) 
This zone set is known as the active zone set. Refer to 
 for information about displaying the active zone set.
