Configuring the OmniSwitch OS6900 with an XNI-U12E Fiber-Channel module expansion module as an NPIV Gateway

OS6900 NPIV Gateway

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 :
