Changes to the FCoE Model and Related Configuration Send documentation comments to [email protected] Each virtual Fibre Channel interface is bound directly to an FCoE-enabled physical Ethernet interface in Release 4.0(1a)N1(1a). This change simplifies the interface vfc command as shown in the following example: switch# configure terminal switch(config)# interface vfc 1 switch(config-if)# bind interface ethernet 1/1 The Ethernet interface that you bind the virtual Fibre Channel interface to must be configured as follows: • It must be a trunk port (use the switchport mode trunk command). • The FCoE VLAN that corresponds to virtual Fibre Channel's VSAN must be in the allowed VLAN list. • FCoE VLAN must not be configured as the native VLAN of the trunk port. • The Ethernet interface must be configured as PortFast (use the spanning-tree port type edge trunk command). VSAN-to-VLAN Mapping In previous Cisco NX-OS 4.0(0)-based releases, FCoE had no dependence on the VLANs defined on the switch. In Release 4.0(1a)N1(1a), each virtual Fibre Channel interface is associated with only one VSAN. Any VSAN with associated virtual Fibre Channel interfaces must be mapped to a dedicated FCOE-enabled VLAN as shown in the following example: switch# configure terminal switch(config)# vlan 200 switch(config-vlan)# fcoe vsan 2 switch(config-vlan)# exit switch(config)# interface ethernet 1/1 switch(config-if)# switchport mode trunk switch(config-if)# switchport trunk native vlan 1 switch(config-if)# switchport trunk allowed vlan 1,200 switch(config-if)# exit switch(config)# interface vfc 1 switch(config-if)# bind interface ethernet 1/1 switch(config-if)# exit switch(config)# vsan database switch(config-vsan)# vsan 2 interface vfc 1 Note The FCoE VLAN must be exclusively reserved for FCoE traffic; it must not be used for non-FCoE Ethernet forwarding.
