Outlined Below are the list of Configuration steps to make the OS6900 act as an NPIV Gateway. The reference topology is attached.
! VLAN:
fcoe vlan 252 admin-state enable [ Create an FCOE vlan]
fcoe vlan 252 name “FCoE VLAN”
! FCOE:
fcoe fip-snooping admin-state enable [ Enable the Fiber-Channel/FCOE protocol on the Switch]
fibre-channel port 1/2/9 mode NP [Connect Fiber-Channel Port 1/2/9 to a Fiber-Channel Switch and configure the mode as NP]
fibre-channel vsan 252 admin-state enable name VSAN252 [ Create a Fiber-Channel VSAN ; Note that this a logical construct to bind the FCOE vlan to the Storage Area Network]
fibre-channel vsan 252 members port 1/2/9 [ Bind the VSAN to the Fiber-Channel NP port]
fcoe vsan-map vsan 252 vlan 252 [ Map Fiber-Channel VSAN with Fcoe VLAN]
! Virtual Flow Control:
qos qsp dcb 16 import qsp dcb “dcp-8” 802.3x-pause [ Create a Custom DataCenter bridging profile which enables PAUSE]
qos qsi port 1/2/9 dcb dcbx pfc tlv disable
qos qsi port 1/2/9 dcb dcbx pfc willing no
qos qsi port 1/2/9 qsp dcb “dcp-16” [ Associate the Profile to the Port. This enables the Port to participate in Fiber-Channel Flow Control by transmitting/receiving R_RDY ]
qos qsi port 1/2/9 dcb dcbx admin-state disable [ Disable DataCenter bridging negotiations on the Fiber-Channel ports as it is only applicable on Ethernet ports]
qos qsi port 1/2/9 dcb dcbx ets willing no
qos qsi port 1/2/9 stats admin-state enable
Here are some Useful validation Commands to check if the OS6900 is indeed acting as an NPIV Gateway :
