Enabling FCoE
To enable FCoE hardware offload on the C-NIC
1. Determine the ports that are FCoE-capable:
# esxcli fcoe nic list
Output example:
vmnic4
User Priority: 3
Source MAC: FF:FF:FF:FF:FF:FF
Active: false
Priority Settable: false
Source MAC Settable: false
VLAN Range Settable: false
1. Enable the FCoE interface:
# esxcli fcoe nic discover -n vmnicX
Where
X
is the interface number gained from
esxcli fcoe nic list.
2. Verify that the interface is working:
# esxcli fcoe adapter list
Output example:
vmhba34
Source MAC: bc:30:5b:01:82:39
FCF MAC: 00:05:73:cf:2c:ea
VNPort MAC: 0e:fc:00:47:04:04
Physical NIC: vmnic7
User Priority: 3
VLAN id: 2008
The output of this command should show valid:
FCF MAC, VNPort MAC, Priority, and VLAN id for the Fabric that is connected to the C-NIC.
The following command can also be used to verify that the interface is working properly:
#esxcfg-scsidevs -a
Output example:
vmhba34 bnx2fc link-up fcoe.1000<mac address>:2000<mac address> () Software FCoE
vmhba35 bnx2fc link-up fcoe.1000<mac address>:2000<mac address> () Software FCoE
NOTE: The label "Software FCoE" is a VMware term used to describe initiators that depend on the inbox FCoE libraries and utilities. Broadcom's FCoE solution is
a fully state connection-based hardware offload solution designed to significantly reduce the CPU burden encumbered by a non-offload software initiator.
Installation Check
To verify the correct installation of the driver and to ensure that the host port is seen by the switch, follow the procedure below.
To verify the correct installation of the driver
1. Verify the host port shows up in the switch FLOGI database using the "show flogi database" command for the case of a Cisco FCF and "fcoe -loginshow"
command for the case of a Brocade FCF.
2. If the Host WWPN does not appear in the FLOGI database, then provide driver log messages for review.
Limitations
NPIV is not currently supported with this release on ESX, due to lack of supporting inbox components.
Non-offload FCoE is not supported with offload-capable Broadcom devices. Only the full hardware offload path is supported.
