> # Disabling CFS Distribution on a Switch

> 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.

> You can globally disable CFS on a switch to isolate the applications using CFS from fabric-wide distributions while maintaining physical connectivity.

> ## Restrictions

> - When CFS is globally disabled on a switch, CFS operations are restricted to the switch and all CFS commands continue to function as if the switch were physically isolated.

> ## Detailed Steps

> To globally disable or enable CFS distribution on a switch, follow these steps:

> 1. In the Physical Attributes pane, expand Switches > CFS.
> 2. In the information pane, from the drop-down menu, choose disable or enable for a switch.
> 3. Click the Apply Changes icon to commit the configuration changes.

> To globally disable or enable CFS distribution on a switch using Device Manager, follow these steps:

> 1. Choose Admin > CFS (Cisco Fabric Services).

> You see the CFS dialog box with the CFS status for all features on that switch.

> 2. Uncheck or check the Globally Enabled check box to disable or enable CFS distribution on this switch.
> 3. Click Apply to disable CFS on this switch.

> ## Enabling CFS for an Application

> ## Restrictions

> - The application configuration is not distributed by CFS unless distribution is explicitly enabled for that application.

> ## Detailed Steps

> To enable CFS for a feature, follow these steps:

> 1. Choose a feature on which to enable CFS. For example, expand Switches > Events, and then select CallHome in the Physical Attributes pane. The Information pane shows that feature with a CFS tab. Click the CFS tab to display the CFS state for each switch in the fabric for that feature.
> 2. Decide on which switch(es) to enable CFS. Set the Admin column to either enable to enable CFS or disable to disable CFS.

> Note Enable CFS for all switches in the fabric or VSAN for the feature that uses CFS.

> 3. Right-click the row you changed to see the pop-up menu. Select Apply Changes to apply the CFS configuration change. The CFS tab updates as the CFS changes take effect.

> DCNM-SAN retrieves the status of the CFS change and updates the Last Result column.

> To enable CFS for a feature using Device Manager, follow these steps:

> 1. Choose Admin > CFS (Cisco Fabric Services).

> You see the CFS dialog box with the CFS status for all features on that switch.

> 2. Decide which features need CFS. Set the Command column to either enable to enable CFS or disable to disable CFS.

> Note Enable or disable CFS for all switches in the fabric or VSAN for the feature that uses CFS.

> 3. Click Pending Differences to compare the configuration of this feature on this switch to other switches in the fabric or VSAN that have CFS enabled for this feature. Close the Show Pending Diff pop-up window.
> 4. Click Apply to apply the CFS configuration change.

> Device Manager retrieves the status of the CFS change and updates the Last Command and Result columns.
