When configuring an FCoE fabric, the first step is to create VLAN-to-VSAN mapping, which allows the logical Fibre 

Channel fabric to transverse the Ethernet network. It is a best practice to have isolated FCoE VLANs that are 

dedicated to FCoE traffic and separate from the rest of the native Ethernet VLANs. You also should not assign VLAN 

1 or VSAN 1 to the FCoE network. Typically, that VLAN and VSAN are used for management traffic or for devices 

that have no other VLAN or VSAN assignment.  

As a result of the practice of isolating FCoE traffic on its own VLAN, any host running FCoE needs to be configured 

as a trunk port rather than an access port. The host port on the Cisco Nexus 5000 Series Switch must also be 

configured as a trunk port (see “Configuring the Adapter Side” later in this document). 

To configure the VLAN-to-VSAN mapping, enter: 

switch# config terminal 

switch(config)# vlan 2 

switch(config-vlan)# fcoe vsan 2 

switch(config-vlan)# end 

 

Note:    The FCoE VSAN must be configured and in the VSAN database of the Cisco Nexus 5000 Series Switch 
before it is mapped to a VLAN. 

As stated earlier, the host-facing ports of the Cisco Nexus 5000 Series Switch need to be configured as trunk ports 

when carrying FCoE traffic. To configure trunking on these ports, enter:
