Enabling FCoE
To make the FC and FCoE features operate correctly, you must enable FCoE.

Enabling FCoE for a VLAN and mapping the VLAN
to a VSAN
When you use an FC or VFC interface to transmit packets, you must configure this feature:
• When you use an FC interface to transmit packets, you must map its access VSAN and trunk VSANs
to VLANs and enable FCoE for the VLANs. This allows the switch to correctly run the FC and FCoE
features.
• When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface
might allow multiple VLANs. You must enable FCoE for a VLAN and map a VSAN to the VLAN.
Then, the packets from the VSAN are tagged with the VLAN tag and transmitted within the VLAN.
After you enable FCoE for a VLAN, the following changes occur on the VLAN:
• An FCoE-capable VLAN allows only FCoE traffic.
• All member ports in an FCoE-capable VLAN are isolated and will not form loops. For this reason,
you do not need to enable STP or other loop detection protocols in an FCoE-capable VLAN.
Otherwise, FCoE links might be blocked.
• A Layer 2 protocol enabled in the FCoE-capable VLAN runs based on the topology where all
member ports in the VLAN are isolated at Layer 2.
Configuration restrictions and guidelines
When you configure this feature, follow these restrictions and guidelines:
• FCoE cannot be enabled for VLAN 1.
• VSANs are mapped to VLANs on a one-to-one basis.
• When you use an FC interface to transmit packets, the VSAN at the two ends can be mapped to the
same VLAN or different VLANs. When you use a VFC interface to transmit packets, you must
enable FCoE for the same VLAN and map this VLAN to the same VSAN at the two ends.
