Zoning a fabric
Fibre Channel fabrics use zoning to restrict or extend access to devices in the fabric. A zone is a
named group of devices that can communicate with each other.
You can use zoning to divide the ports and devices of the fabric into zones for more efficient and
secure communication among functionally grouped nodes. You can set the Auto Save and Default
Visibility zoning configuration parameters using the SAN Utility or the Set Config Zoning
command. See "Auto save" on page 85 for information about the Auto Save parameter, see "Default
visibility" on page 86 for information about the Default Visibility parameter, and see "Using the
Zoning Config window" on page 86 for information about the Set Config Zoning command.
Zoning concepts
The following zoning concepts provide some context for the zoning tasks described in this section:
• Zones
• Aliases
• Zone sets
• Zoning database
• Zoning configuration
Zones
A zone is a named group of ports or devices that can communicate with each other. Membership in a
zone is defined by port number, device Fibre Channel address, or device World Wide Name (WWN).
Zone members can communicate only with members of the same zone. Zones can overlap; that is, a
port or device can be a member of more than one zone.
There are three zone types that are supported but have restrictive levels of communication. These
zone types are:
• Soft zone
• Access control list (ACL) - hard zone
