> # Enabling FCoE

> Fibre Channel over Ethernet (FCoE) provides a method of transporting Fibre Channel traffic over a physical Ethernet connection. By default, each Ethernet interface attempts to enable FCoE by advertising that it has FCoE to the adapter. If the FCoE negotiation fails, you can configure the Cisco Nexus 5000 Series switch to disable FCoE for this interface.

> Note In Cisco Nexus 5000 Series switches, FCoE is supported on all 10-Gigabit Ethernet interfaces.

> ## Detailed Steps

> To enable or disable FCoE features on a switch using Device Manager, follow these steps:

> 1. Launch Device Manager from the Cisco Nexus 5000 Series switch.

> Note Use the Control tab to enable FCoE on a Cisco Nexus 5000 Series switch.

> 2. Choose Admin > Feature Control.

> You see the Feature Control dialog box.

> Note You cannot enable FCoE using Device Manager on Cisco Nexus 7000 series and Cisco MDS 900 family switches. Cisco Nexus 7000 series and Cisco MDS 9000 Family switches uses a feature set to display FCoE information.

> 3. In the dialog box, in the table, click the fcoe_mgr row, and then click the Action cell in the fcoe_mgr row. From the drop-down list, choose enable to enable the FCoE feature in the switch.

> Note You can also disable the FCoE feature in the switch. To do so, from the drop-down list in the Action column, choose disable.

> 4. Click Apply.

> Note If the Cisco Nexus 5000 Series switch is running a Cisco NX-OS release prior to Release 4.2(1), you must do the following after you enable or disable FCoE on the switch:
> • In the confirmation dialog box that appears, click Yes to enable the FCoE feature in the switch.
> • Reboot the switch before you use the FCoE feature.
