Active and Full Zone Set Configuration Guidelines Configuring and Managing Zones • Hard zoning cannot be disabled. • Name server queries are soft-zoned. • Only active zone sets are distributed. • Unzoned devices cannot access each other. • A zone or zone set with the same name can exist in each VSAN. • Each VSAN has a full database and an active database. • Active zone sets cannot be changed, without activating a full zone database. • Active zone sets are preserved across switch reboots. • Changes to the full database must be explicitly saved. • Zone reactivation (a zone set is active and you activate another zone set) does not disrupt existing traffic. If required, you can additionally configure the following zone features: • Propagate full zone sets to all switches on a per VSAN basis. • Change the default policy for unzoned members. • Interoperate with other vendors by configuring a VSAN in the interop mode. You can also configure one VSAN in the interop mode and another VSAN in the basic mode in the same switch without disrupting each other. • Bring E ports out of isolation. Active and Full Zone Set Configuration Guidelines Before configuring a zone set, consider the following guidelines: • Each VSAN can have multiple zone sets but only one zone set can be active at any given time. • When you create a zone set, that zone set becomes a part of the full zone set. • When you activate a zone set, a copy of the zone set from the full zone set is used to enforce zoning, and is called the active zone set. An active zone set cannot be modified. A zone that is part of an active zone set is called an active zone. • The administrator can modify the full zone set even if a zone set with the same name is active. However, the modification will be enforced only upon reactivation. • When the activation is done, the active zone set is automatically stored in persistent configuration. This enables the switch to preserve the active zone set information across switch resets. • All other switches in the fabric receive the active zone set so they can enforce zoning in their respective switches. • Hard and soft zoning are implemented using the active zone set. Modifications take effect during zone set activation. • An FC ID or Nx port that is not part of the active zone set belongs to the default zone and the default zone information is not distributed to other switches.
