On Cisco Nexus 5000 Series switches, Fibre Channel capability is included in the Storage Protocol
Services license.
Ensure that you have the correct license installed (N5010SS or N5020SS) before using Fibre Channel
interfaces and capabilities.
Note You can configure virtual Fibre Channel interfaces without a Storage Protocol Services license, but these
interfaces will not become operational until the license is activated.
