> # Taking Interfaces Out of Service

> You can take interfaces out of service on Generation 2 and Generation 3 switching modules. When an interface is out of service, all the shared resources for the interface are released as well as the configuration associated with those resources.

> ## Prerequisites

> - The interface must be disabled before it can be taken out of service.

> ## Restrictions

> - The interface cannot be a member of a PortChannel.
> - Taking interfaces out of service releases all the shared resources to ensure that they are available to other interfaces. This causes the configuration in the shared resources to revert to default when the interface is brought back into service. Also, an interface cannot come back into service unless the default shared resources for the port are available. The operation to free up shared resources from another port is disruptive.

> ## Detailed Steps

> To take an interface out of service using DCNM-SAN, follow these steps:

> 1. Select a switch from the Fabric pane, or select a group of switches (SAN, fabric, VSAN) from the Logical Domains pane.
> 2. Expand Switches, and expand FC Interfaces > Physical in the Physical Attributes pane.
> 3. Click General tab. You see the General tab information in the Information pane.
> 4. Scroll down until you see the row containing the switch and port you want to configure.
> 5. Scroll right (if necessary) until you see the Status Service column.
> 6. Select in or out from the Status Service column.
> 7. Click the Apply Changes icon.
