Enabling FCoE

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

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.
