Zoning Concepts Zoning Schemes Zone schemes are the method in which a zone is established. A zone is established by identifying zone objects by using one or more of the following schemes: the switch and port, World Wide Name (WWN), or AL_PA. The zoning schemes are defined below. Switch/Port Level Zoning A zone containing members specified by either domain ID with port number or area number, or aliases of . For information about specifying ports and area numbers, refer to Table 2 on page 23. WWN Level Zoning A zone containing members specified only by device World Wide Names (WWNs), or aliases of WWNs. AL_PA Level Zoning Members of a QuickLoop are specified by the AL_PA when zoned. Identification other than AL_PAs in a QuickLoop cannot be used. Mixed Zoning A zone containing members specified by a combination of WWN and switch port number or area number. Mixed zones are software enforced through the fabric name server only. Zone Enforcement Zones are either hardware enforced or software enforced depending on the scheme that is used. When a zone is specified by either port number (area number) or WWN, but not both, it will be a hardware-enforced zone. When a zone is specified by both port number and WWN, it is a software-enforced zone. Hardware-enforced zoning is enforced at the ASIC level with support from the Name Server. Each ASIC maintains a list of source port IDs that have permission to access any of the ports on that ASIC. Software-enforced zoning is exclusively enforced through selective information presented to end nodes through the fabric Simple Name Server (SNS). 28 Zoning Version 3.1.x/4.1.x User Guide
