Disabling or Enabling CFS Distribution on a Switch

You can clear locks held by a feature from any switch in the fabric. This option is provided to rescue you

from situations where locks are acquired and not released. This function requires administrative

permissions.

Caution Exercise caution when using this function to clear locks in the fabric. Any pending configurations in any

switch in the fabric is flushed and lost.

Disabling or Enabling 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.

As of Cisco MDS SAN-OS Release 2.1(1a), you can globally disable CFS on a switch to isolate the

applications using CFS from fabric-wide distributions while maintaining physical connectivity. 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.

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

Step 1 Choose any CFS feature. For example, choose Switches > Events > CallHome from the Physical

Attributes pane. The Information pane shows that feature, with a CFS tab.

Step 2 Click the CFS tab to display the CFS state for each switch in the fabric for that feature.

Step 3 Set the Enable > Global drop-down menu to disable or enable for all switches that you want to disable

or enable CFS on.

Step 4 Set the Config Changes > Action column to commit.

Step 5 Click the Apply Changes to commit the configuration changes for that feature and distribute the changes

through CFS, or click Undo Changes to discard the changes for that feature.

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

Step 1 Select Admin > CFS from the main menu. You see the CFS dialog box with the CFS status for all

features on that switch.

Step 2 Uncheck or check the Globally Enabled check box to disable or enable CFS distribution on this switch.

Step 3 Select Apply to disable CFS on this switch or Close to close the dialog box without making changes.
