SCP on Nexus devices

[glen.grant]

    Have a couple of Nexus 5596 running  n5000-uk9.5.1.3.N2.1.bin  .   For some reason "feature scp"  is not an option on these boxes.

in documentation  it says it should be available as of 5.1.1 .  How come it is not available.  Is this the wrong feature set ?  You would think something this would be available on all feature sets. 

SCP and SFTP servers

5.1(1)

Added the ability to configure SCP and SFTP servers on the Cisco NX-OS device to support the copy of files to and from a remote device.

   I have found out you need to have at least  6.0(2)N1(1).   to have scp feature on nexus 5000's.
