Zone merging
11
If the zoneset members on two switches are not listed in the same order, the configuration is
considered a mismatch, resulting in the switches being segmented from the fabric. For
example:
cfg1 = z1; z2 is different from cfg1 = z2; z1, even though members of the
configuration are the same. If zoneset members on two switches have the same names
defined in the configuration, make sure zoneset members are listed in the same order.
Fabric segmentation and zoning
If the connections between two fabrics are no longer available, the fabric segments into two
separate fabrics. Each new fabric retains the same zone configuration.
If the connections between two fabrics are replaced and no changes have been made to the zone
configuration in either of the two fabrics, then the two fabrics merge back into one single fabric. If
any changes that cause a conflict have been made to either zone configuration, then the fabrics
might segment.

TABLE 52 Zone merging scenarios: Defined and effective configurations
Description Switch A Switch B Expected results
Switch A has a defined configuration.
Switch B does not have a defined
configuration.
defined:
cfg1:
zone1: ali1; ali2
effective: none
defined: none
effective: none
Configuration from Switch A to propagate
throughout the fabric in an inactive state,
because the configuration is not enabled.
Switch A has a defined and effective
configuration.
Switch B has a defined configuration
but no effective configuration.
defined: cfg1
zone1: ali1; ali2
effective: cfg1:
defined: cfg1
zone1: ali1; ali2
effective: none
Configuration from Switch A to propagate
throughout the fabric. The configuration is
enabled after the merge in the fabric.
Switch A and Switch B have the same
defined configuration. Neither have an
effective configuration.
defined: cfg1
zone1: ali1; ali2
effective: none
defined: cfg1
zone1: ali1; ali2
effective: none
No change (clean merge).
Switch A and Switch B have the same
defined and effective configuration.
defined: cfg1
zone1: ali1; ali2
effective: cfg1:
defined: cfg1
zone1: ali1; ali2
effective: cfg1:
No change (clean merge).
Switch A does not have a defined
configuration.
Switch B has a defined configuration.
defined: none
effective: none
defined:cfg1
zone1: ali1; ali2
effective: none
Switch A will absorb the configuration from the
fabric.
