Merging Zoned Fabrics

Managed products are linked through ISLs to form multiswitch fabrics. In a
multiswitch fabric, the active zoning configuration applies to the entire fabric.
Any change to the configuration applies to all switches in the fabric.

Configurations of Merged Zoned Fabrics

When fabrics join through an ISL, adjacent managed products exchange active
zone configurations and determine if the configurations are compatible and can
merge. If the configurations can merge, the fabrics join. The resulting
configuration will be a single zone set containing zone definitions from each
fabric.
If configurations cannot merge, the expansion ports (E_Ports) on each product
become segmented. Segmented E_Ports cannot carry traffic from attached devices
(class 2 or 3 traffic), but can carry management and control traffic (class F traffic)
between managed products.
Zoning configurations are compatible if the active zone names in each fabric are
unique. If there are identical zone names in each fabric, then the zones must have
identical members for the fabrics to join.

Rules for Merging Zoned Fabrics

Certain rules are enforced to ensure that zoning is consistent across the fabric.

terms are used in the table:
High Availability Fabric Manager User Guide
summarizes rules for joining two fabrics through an ISL. The following
Not zoned
No zone set is active in the fabric and the default zone is enabled. In other
words, all devices in the fabric are visible to all other devices in the fabric.
Zoned
A zone set is active in the fabric and/or the default zone is disabled. In this
case, devices can discover other devices that are members of the same zone.
Zoning configuration
Combination of the active zone set definition and the default zone state
