Step 4
If you have the rcf-reject option enabled, use the

Step 5
Use the

Step 6
Use the

Cisco Fabric Services
This section includes an overview of troubleshooting Cisco Fabric Services (CFS) followed by a
description of common problems and their solutions.
Overview
Begin troubleshooting CFS issues by checking the following:
•
Verify that CFS is enabled for the same applications on all affected switches.
•
Verify that CFS distribution is enabled for the same applications on all affected switches.
If the CFS Regions feature is in use, verify that the application is in the same region on all the
affected switches.
•
Verify that there are no pending changes for an application and that a CFS commit was issued for
any configuration changes in a CFS-enabled application.
•
Verify that there are no unexpected CFS locked sessions.
Clear any unexpected locked sessions.
Verifying CFS using CLI
To verify CFS using the CLI, follow these steps:
Step 1
By default, CFS distribution is enabled. Applications can distribute data and configuration information
to all CFS-capable switches in the fabric where the applications exist. This is the normal mode of
operation. To determine the state of CFS distribution on a switch, enter the
show cfs status
command.
Example:
