• Each VSAN can have multiple zone sets, each zone set can have multiple zones, and each zone
can have multiple zone members.
• To facilitate configuration, zone membership configuration supports use of zone aliases. A zone
alias is a set of N_Ports, which can be considered as a whole. You can add common zone members
in multiple zones to a zone alias, and call 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 on a fabric-wide basis, you must specify the active zone
set by using a command on a local device 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 25 shows the relationship between active and full zone sets.
