Usecase 1 - NPG fabric is connected to an FCF switch through multiple links

Consider a topology where the gateway switch is connected to an upstream switch through multiple links.

The gateway switch is an OS10 switch operating in NPG mode and with two FC upstream interfaces (fc 1/1/1 and fc 1/1/2) having a speed of 16G.

Two FCoE end points(CNAs) are attached to ports eth 1/1/54 and eth 1/1/55 and they carry FCoE traffic. FC end points (HBAs) are attached to ports fc 1/1/9 and fc 1/1/10 and they carry pure FC traffic.

Both FCoE traffic and FC traffic is balanced across the FC upstream interfaces (fc 1/1/1 and fc 1/1/2) available in the NPG switch.

Following configurations are to be done in the NPG switch:

NPG Device Configuration

Enable NPG Mode of operation 
OS10# show fc switch
Switch Mode : Disabled
Switch WWN :

OS10(config)# feature fc npg

OS10# show fc switch
Switch Mode : NPG
Switch WWN : 10:00:14:18:77:20:73:cf
OS10#
VLAN creation 
OS10(config)# interface vlan 100
vFabric Creation 
OS10(config)# vfabric 100

OS10(conf-vfabric-100)# vlan 100

OS10(conf-vfabric-100)# name NPG_Fabric

OS10(conf-vfabric-100)# fcoe fcmap 0efc01

OS10(conf-vfabric-100)# exit
Apply vFabric configuration on the FC upstream interfaces 
OS10(config)# interface range fibrechannel 1/1/1,1/1/2

OS10(conf-range-fc1/1/1,1/1/2)# vfabric 100

OS10(conf-range-fc1/1/1,1/1/2)# no shut

OS10(conf-range-fc1/1/1,1/1/2)# exit
Apply vFabric and FC port-mode configuration on the interface that connects to FC End points(HBA) 
OS10(config)# interface range fibrechannel 1/1/9,1/1/10

OS10(conf-range-fc1/1/9,1/1/10)# vfabric 100

OS10(conf-range-fc1/1/9,1/1/10)# fc port-mode F

OS10(conf-range-fc1/1/9,1/1/10)# no shut

OS10(conf-range-fc1/1/9,1/1/10)# exit
Enable DCBx Globally 
OS10(config)# dcbx enable
Class map and Policy map creation 
OS10(config)# class-map type network-qos cmap1

OS10(config-cmap-nqos)# match qos-group 3

OS10(config)# policy-map type network-qos pmap1

OS10(config-pmap-network-qos)# class cmap1

OS10(config-pmap-c-nqos)# pause

OS10(config-pmap-c-nqos)# pfc-cos 3

OS10(config-pmap-c-nqos)# exit
Disable LLFC on the interface that connects to FCoE End points(CNA) 
OS10(config)# interface range ethernet 1/1/54,1/1/55

OS10(conf-range-eth1/1/54,1/1/55)# no flowcontrol receive
Apply Service policy and Enable PFC mode on the interface that connects to FCoE End points(CNA) 
OS10(conf-range-eth1/1/54,1/1/55)# service-policy input type network-qos pmap1

OS10(conf-range-eth1/1/54,1/1/55)# priority-flow-control mode on
Apply vFabric configuration on the interface that connects to FCoE End points(CNA) 
OS10(conf-range-eth1/1/54,1/1/55)# vfabric 100

OS10(conf-range-eth1/1/54,1/1/55)# no shut

OS10(conf-range-eth1/1/54,1/1/55)# exit
Apply fcoe delay FCF advertisement configuration globally (This is optional) 
OS10(config)# fcoe delay fcf-adv 15

Upstream switch(FPORT/Multi-switch) Configuration

Enable FPORT/Multi-switch Mode of operation 
OS10# show fc switch
Switch Mode : Disabled
Switch WWN :

If user want FPORT mode then,

OS10(config)# feature fc domain id 10

OS10# show fc switch
Switch Mode : FPORT
Switch WWN : 10:00:14:18:77:20:73:cf
OS10#

or if they want Multi-switch mode then configure the following,

OS10(config)# feature fc multi-switch

OS10# show fc switch
Switch Mode : MULTI-SWITCH
Switch WWN : 10:00:14:18:77:20:73:cf
OS10#
VLAN creation 
OS10(config)# interface vlan 10
vFabric Creation 
OS10(config)# vfabric 10

OS10(conf-vfabric-10)# vlan 10

OS10(conf-vfabric-10)# name FPORT_Fabric

OS10(conf-vfabric-10)# fcoe fcmap 0efc01

OS10(conf-vfabric-10)# exit
Apply vFabric configuration on the FC interfaces connected to NPG device 
OS10(config)# interface range fibrechannel 1/1/1,1/1/2

OS10(conf-range-fc1/1/1,1/1/2)# vfabric 10

OS10(conf-range-fc1/1/1,1/1/2)# no shut

OS10(conf-range-fc1/1/1,1/1/2)# exit
