QuestionQ173

Storage Network

An engineer must deploy FCoE on Cisco Nexus 9000 Series Switch-based infrastructure. The deployment will include dual-homed fabric extenders and must support jumbo frames using port channels. Which two sets of actions complete the configuration?

Choose two
  • A Create a virtual Fibre Channel Interface. Bind vFC to physical interface.
  • B Configure the interface with mtu 9516. Disable the feature NPIV.
  • C Create a dedicated VSAN for FEX. Bind VSAN to FEX uplinks.
  • D Execute fcoe enable-fex. Configure FEX uplinks with mtu 9216.
  • E Create a FCoE switch profile. Enable config sync.
Explanation

FCoE over a dual-homed Fabric Extender requires fcoe enable-fex so FCoE host logins through FEX host interfaces function correctly, and requires MTU 9216 on the FEX fabric port-channel/uplinks to carry jumbo FCoE frames. FCoE traffic is presented through a virtual Fibre Channel interface that is bound to its underlying Ethernet interface. Cisco documents both the FEX enablement and the 9216-byte FEX fabric-port-channel MTU, as well as vFC binding requirements.
