Similar to the iSCSI application, when using the Emulex VFA for Lenovo chassis
systems, FCoE traffic is expected to occur only on vNIC pipe 2. In this case, the
additional vNIC configuration for FCoE support is minimal.
Consider an example where the Fibre Channel network is connected to an FCoE
Forwarder (FCF) bridge via bridge port EXT4, and to an ENode on port INT1.
"FIP Snooping Configuration" on page
a. Disable the FIP Snooping automatic VLAN creation.
b. Disable FIP Snooping on all external ports not used for FCoE. FIP snooping
should be enabled only on ports connected to an FCF or ENode.
c. Turn on CEE and FIP Snooping.
d. Manually configure the FCoE ports and VLAN: enable VLAN tagging on all
FCoE ports, and place FCoE ports into a supported VLAN.
When CEE is turned on and the regular FCoE configuration is complete, FCoE
traffic will be automatically assigned to PFC priority 3, and be initially allocated
50% of port bandwidth via ETS.
The following steps are specific to vNIC configuration.
Emulex VFA documentation for details.
CN 4093 # vnic enable
CN 4093(config)# fcoe fips port INT1 fcf-mode off
(Select ENode port; Set as ENode connection)
CN 4093(config)# fcoe fips port EXT4 fcf-mode on
(Select FCF port; Set as FCF connection)
No additional configuration for vNIC pipes or vNIC groups is required for FCoE.
However, for other networks connected to the switch, appropriate vNIC pipes and
vNIC groups should be configured as normal, if desired.
