Locking the Fabric Chapter 13 Using the CFS Infrastructure Send documentation comments to [email protected] The application configuration is not distributed by CFS unless distribution is explicitly enabled for that application. To enable CFS for a feature using Fabric Manager, follow these steps: Step 1 Step 2 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. 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. Step 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. Fabric Manager 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: Step 1 Step 2 Choose Admin > CFS (Cisco Fabric Services). You see the CFS dialog box with the CFS status for all features on that switch. Decide which feature(s) 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. Step 3 Step 4 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. 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. Locking the Fabric When you configure (first time configuration) a Cisco NX-OS feature (or application) that uses the CFS infrastructure, that feature starts a CFS session and locks the fabric. When a fabric is locked, the Cisco NX-OS software does not allow any configuration changes from a switch to this Cisco NX-OS feature, other than the switch holding the lock, and issues a message to inform the user about the locked status. The configuration changes are held in a pending database by that application. If you start a CFS session that requires a fabric lock but forget to end the session, an administrator can clear the session. If you lock a fabric at any time, your user name is remembered across restarts and switchovers. If another user (on the same machine) tries to perform configuration tasks, that user's attempts are rejected. 13-6 Cisco MDS 9000 Family Fabric Manager Configuration Guide OL-17256-03, Cisco MDS NX-OS Release 4.x
