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 following rules apply to hard zones:

„ACL zones can overlap; that is, a port can be a member of more than one ACL zone.

„Do not create a hard zone that shares membership with a soft zone. Soft zone members that are in the hard zone will not be able to transfer I/O with soft zone members that are outside of the hard zone.

„ACL zones that include members from multiple switches need not include the ports of the inter-switch links.

„Membership can be defined only by domain ID and port number. Members defined by other methods will revert to soft zones.

„ACL zoning supports all port types.

3.6.1.2

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. You cannot add a zone to an alias, nor can an alias be a member of another alias.

3.6.1.3

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 “Configured Zonesets Data Window” on page 4-12for 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. Refer to “Active Zone Set Data Window” on page 3-16for information about displaying the active zone set.
