A table containing information on all currently
enforced zone sets (active zone sets) on all VSANs.
Only one zone set can be activated per VSAN. The
active zone set is one which is copied from the
zone set database (zoneSetTable) at the time it
was activated. This active zone set is then
enforced on the fabric. This active zone set
cannot be modified.
Note that this table will be empty when no zone set
is activated.
