You cannot create a CFS Region in the logical scope of an application. • Assigning a region to an application takes precedence in distribution over its initial physical scope. • For backwards compatibility, all applications are in Region 0 by default. If you are running switches with previous SAN-OS releases on the same topology as switches running SAN OS 3.2x, only applications in Region 0 are supported when those switches are synchronized. Only Region 0 applications on the switches running SAN-OS 3.2x synchronize or merge with switches running SAN-OS 3.1x. All applications in other regions on the switch running SAN-OS 3.2x are ignored by the switch running SAN-OS 3.1x. • CFS Regions configuration is not supported for deregistered applications (conditional services) or a physical scope application that is currently locked. • Regions 1 through 200 are available for user configuration. Regions 201 through 255 are reserved regions and are not available for user configuration. Distribution Failure To resolve a configuration distribution failure to all switches for a CFS Region, follow these steps: Step 1 Step 2 Verify that application distribution is enabled. See "Initial Troubleshooting Checklist" section on page 7-2 for detailed instructions. Verify that the application is in the same region on all switches. From Fabric Manager, select the application tab (for example, Physical Attributes > Switches > Clock > NTP), and then click the CFS tab. Find the region-id column and check that the source switch and destination switch are in the same region.and click the Regions tab. Using the CLI from each switch, issue the show cfs application name application-name command. For example, for the device-alias application: Switch# show cfs application name device-alias Enabled Timeout Merge Capable Scope Region : Yes : 20s : Yes : Physical-fc : 1

CFS Regions Troubleshooting
The following rules apply to CFS Regions:
When using CFS Regions, an application on a given switch can only belong to one region at a time.
CFS Regions are only applicable to applications within physical scope. You cannot create a CFS
Region in the logical scope of an application.
Assigning a region to an application takes precedence in distribution over its initial physical scope.
For backwards compatibility, all applications are in Region 0 by default. If you are running switches
with previous SAN-OS releases on the same topology as switches running SAN OS 3.2x, only
applications in Region 0 are supported when those switches are synchronized. Only Region 0
applications on the switches running SAN-OS 3.2x synchronize or merge with switches running
SAN-OS 3.1x. All applications in other regions on the switch running SAN-OS 3.2x are ignored by
the switch running SAN-OS 3.1x.
CFS Regions configuration is not supported for deregistered applications (conditional services) or
a physical scope application that is currently locked.
Regions 1 through 200 are available for user configuration. Regions 201 through 255 are reserved
regions and are not available for user configuration.
Distribution Failure
To resolve a configuration distribution failure to all switches for a CFS Region, follow these steps:
Step 1
Verify that application distribution is enabled. See
“Initial Troubleshooting Checklist” section on
page 7-2
for detailed instructions.
Step 2
Verify that the application is in the same region on all switches. From Fabric Manager, select the
application tab (for example,
Physical Attributes
> Switches > Clock > NTP
), and then click the
CFS
tab. Find the region-id column and check that the source switch and destination switch are in the same
region.and click the Regions tab.
Using the CLI from each switch, issue the
show cfs application name
application-name
command.
For example, for the device-alias application:
Switch#
show cfs application name device-alias
Enabled
: Yes
Timeout
: 20s
Merge Capable
: Yes
<<<<<< Application is capable of being merged.
Scope
: Physical-fc
Region
: 1
<<<<<< Application is in Region 1
