Step 7. (Optional.) Restore the default settings for the VFC interface. 8. Bring up the VFC interface. Command default undo shutdown Remarks N/A By default, a VFC interface is up. Enabling FCoE for a VLAN and mapping a VSAN to the VLAN When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface can allow multiple VLANs. You should enable FCoE for a VLAN and map a VSAN to the VLAN, so that the packets from the VSAN are tagged with the VLAN tag and transmitted within the VLAN. Configuration restrictions and guidelines Follow these restrictions and guidelines when you configure this feature: • FCoE cannot be enabled for VLAN 1. • VSANs are mapped to VLANs on a one-to-one basis. • You must enable FCoE for the same VLAN and map this VLAN to the same VSAN on the two ends. • Make sure the Ethernet interface bound to the VFC interface allows the FCoE-capable VLAN. After you enable FCoE for a VLAN, the following changes apply to the VLAN: • An FCoE-capable VLAN allows only FCoE traffic. • All member ports in an FCoE-capable VLAN are isolated at Layer 2 to avoid loops. For this reason, STP and other loop detection protocols do not need to run in an FCoE-capable VLAN. Otherwise, FCoE links might be blocked. • Because all member ports in an FCoE-capable VLAN are isolated, a Layer 2 protocol enabled in the FCoE-capable VLAN runs based on the port isolation topology. Configuration procedure To enable FCoE for the specified VLAN and map this VLAN to the specified VSAN: Step 1. Enter system view. 2. Enter VLAN view. 3. Enable FCoE for the specified VLAN and map this VLAN to the specified VSAN. Command system-view vlan vlan-id fcoe enable [ vsan vsan-id ] Remarks N/A N/A By default, FCoE for a VLAN is disabled.

Enabling FCoE for a VLAN and mapping a VSAN
to the VLAN
When you use a VFC interface to transmit packets, the Ethernet interface bound to the VFC interface can
allow multiple VLANs. You should enable FCoE for a VLAN and map a VSAN to the VLAN, so that the
packets from the VSAN are tagged with the VLAN tag and transmitted within the VLAN.
Configuration restrictions and guidelines
Follow these restrictions and guidelines when you configure this feature:
•
FCoE cannot be enabled for VLAN 1.
•
VSANs are mapped to VLANs on a one-to-one basis.
•
You must enable FCoE for the same VLAN and map this VLAN to the same VSAN on the two ends.
•
Make sure the Ethernet interface bound to the VFC interface allows the FCoE-capable VLAN.
After you enable FCoE for a VLAN, the following changes apply to the VLAN:
•
An FCoE-capable VLAN allows only FCoE traffic.
•
All member ports in an FCoE-capable VLAN are isolated at Layer 2 to avoid loops. For this reason,
STP and other loop detection protocols do not need to run in an FCoE-capable VLAN. Otherwise,
FCoE links might be blocked.
•
Because all member ports in an FCoE-capable VLAN are isolated, a Layer 2 protocol enabled in
the FCoE-capable VLAN runs based on the port isolation topology.
