Zone management in interoperable fabrics
Safe zoning mode
The safe zoning mode is a fabric-wide parameter that ensures that the resulting zone set of two
merged fabrics is consistent with the pre-merged zone sets. When you enable the safe zoning
mode, the default zoning mode must be disabled and the zoning configuration of neighboring
switches must match completely before the zoning can merge.
ATTENTION
Safe zoning mode is only available in fabrics with their interoperable mode set to 2.
With safe zoning enabled, the effective configurations must match exactly. Also, it does not allow the
default zone to be enabled.
To allow a Fabric OS switch into an M-EOS native fabric, safe zoning mode must be disabled. This
allows the Fabric OS switch to join the fabric although the zone sets do not match. After the fabric
merge and zone merge are completed, safe zoning may be re-enabled.
Setting the safe zone mode on a stand-alone switch
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the switchDisable command.
3. Enter the interopMode command.
Setting the safe zone mode fabric-wide
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the cfgMcdtMode command.
NOTE
The interopMode and cfgMcdtMode commands perform the same basic functions. However,
the interopMode command only affects the local configuration and the command must be issued
on each switch in the fabric. The cfgMcdtMode affects the entire fabric.
Disabling safe zone mode
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the cfgMcdtMode command.
