Figure 22 Zone database structure
In the zone database structure:
• A zone set is a set of zones. A zone is a set of zone members, which are N_Ports or F_Ports. N_Port
membership can be identified by the port WWN (pWWN) or FC address of an N_Port. F_Port
membership can be identified by the WWN of an F_Port (fWWN).
• Each VSAN can have multiple zone sets, each zone set can have multiple zones, and each zone
can have multiple zone members.
• Zone membership configuration supports use of zone aliases. A zone alias is a set of N_Ports,
which can be considered as a whole. To simplify configuration, you can add common zone
members in multiple zones to a zone alias, and use the zone alias in different zones to simplify
configuration.
Active zone set
Each VSAN can have multiple zone sets, but only one zone set can be effective at a time. It is called the
active zone set. Access control over N_Ports is subject to the active zone set.
To ensure consistent access control over N_Ports across a fabric basis, specify a zone set as the active
zone set on a switch and distribute it to the entire fabric.
When you activate a zone set, a copy of the zone set at the time of activation is created and is called the
active zone set. After that, modifications to the zone set do not take effect on the copy until the copy is
reactivated. Figure 23
shows the relationship between active and full zone sets.
