Hard zones (Access Control Lists)

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 zone boundaries supersede soft zone boundaries.

■ Membership can be defined only by domain ID and port ID. A switch port can be a

member of multiple ACL zones whose combined membership does not exceed 128.

Soft zones

Soft zoning divides the fabric for purposes of controlling device discovery. Devices in 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. The following rules apply to soft zones:

■ 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

worldwide name.

■ Soft zoning supports FL_Ports and F_Ports.

MaxZonesInZoneSets Maximum number of zones that are

components of zone sets, excluding the

orphan zone set, which can be stored in the

switch zoning database. Each instance of a

zone in a zone set counts toward this

maximum.

1000

MaxMembersPerZone Maximum number of members in a zone that

can be stored in the switch zoning database.

2000

MaxMembersPerAlias Maximum number of members in all zones

and aliases.

2000
