You can configure different IVR configurations in different Cisco MDS switches.
•
Be aware that the merge follows more liberal approach in order to avoid traffic disruption. After the
•
merge, the configuration will be a union of the configurations that were present on the two switches
involved in the merge.
VSANs with the same VSAN ID but different AFIDs are counted as two separate VSANs.
Note
OL-16184-01, Cisco MDS SAN-OS Release 3.x
If dissimilar zones exist in two merged fabrics, the zone from each fabric is cloned in the
–
distributed zone set with appropriate names (see

dissimilar zones

The configurations are merged even if both fabrics have different configurations.
–
A union of zones and zone sets are used to get the merged zones and zone sets. If a dissimilar
–
zone exists in two fabrics, the dissimilar zones are cloned into the zone set with appropriate
names so both zones are present.
The merged topology contains a union of the topology entries for both fabrics.
–
The merge will fail if the merged database contains more topology entries than the allowed
–
maximum.
The total number of VSANs across the two fabrics cannot exceed 128.
–
The total number of IVR-enabled switches across the two fabrics cannot exceed 128.
–
The total number of zone members across the two fabrics cannot exceed 10,000. As of Cisco
–
SAN-OS Release 3.0(3), the total number of zone members across the two fabrics cannot exceed
20,000. A zone member is counted twice if it exists in two zones.
