Enabling FCoE for a VLAN and mapping the VLAN
to a VSAN
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, so that the device can 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 one of these VLANs 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.
After you enable FCoE for a VLAN, the following changes occur to 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 and other loop detection protocols in an FCoE-capable VLAN.
Otherwise, FCoE links might be blocked.
•
A Layer 2 protocol enabled in an FCoE-capable VLAN runs based on the topology where all
member ports in the FCoE-capable 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 is not required to be
mapped to the same VLAN. 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.
•
Make sure the Ethernet interface bound to the VFC interface allows the FCoE-capable VLAN.
