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:

Step 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.

Step 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.

Step 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.

Step 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.

Configuring FCoE Using DCNM for SAN

From Cisco NX-OS Release 5.2, FCoE is supported on MDS and Cisco Nexus 7000 switches. To enable or disable FCoE, Cisco MDS 9000 Family and Cisco Nexus 7000 switches uses feature set MIBs.

Detailed Steps

To configure FCoE on a switch, follow these steps:

Step 1 In the Physical Attributes pane, choose Switches > FC Services > FCoE .

You see the FCoE information pane shown in Figure 17-1.

The Config tab displays the FCoE parameters for each Cisco Nexus 5000 Series, Cisco Nexus 7000 Series, and Cisco MDS 9000 Family switches. Use the VLAN-VSAN mapping tab to create mappings. Table 17-1 lists the FCoE parameters for a switch.

For more information on configuring Cisco Nexus 5000 Series and Nexus 7000 Series switches, see the Cisco Nexus 5000 Series and Nexus 7000 Series Configuration Guides.

Step 2 Double-click the relevant FCoE parameter for a switch, and modify the value of the parameter.

Step 3 In the Information pane toolbar, click the Apply Changes icon to save the changes.

Configuring FCoE Using Device Manager

Detailed Steps

To configure FCoE on a switch using Device Manager, follow these steps:

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

Step 2 Choose FCoE > Config .

You see the FCoE Config dialog box shown in Figure 17-2.

The Config tab displays the FCoE parameters, such as FC Map, default FCF priority value, and FKA advertisement period, for each Cisco Nexus 5000 Series switch that runs Cisco NX-OS Release 4.1(3) or later releases. Table 17-1 lists the FCoE parameters for a switch.

Step 3 Double-click the relevant FCoE parameter for a switch, and modify the value of the parameter.

Step 4 Click Apply to save the changes.
