> # Enabling Distribution

> ## Detailed Steps

> All the configurations performed in distributed mode are stored in a pending (temporary) database. If you modify the configuration, you need to commit or discard the pending database changes to the configurations. The fabric remains locked during this period. Changes to the pending database are not reflected in the configurations until you commit the changes.

> Note Port activation or deactivation and auto-learning enable or disable do not take effect until after a CFS commit if CFS distribution is enabled. Always follow any one of these operations with a CFS commit to ensure proper configuration. See the "Activation and Auto-learning Configuration Distribution" topic.

> Tip In this case, we recommend that you perform a commit at the end of each operation: after you activate port security and after you enable auto learning.

> To enable distribution, follow these steps:

> 1. Expand a VSAN and select Port Security in the Logical Domains pane.

> You see the port security configuration for that VSAN in the Information pane.

> 2. Click the Control tab.

> You see the switches for that VSAN.

> 3. In the Command column, select enable or disable from the drop-down menu.
> 4. Click the Apply Changes icon to save the changes.
