Symptom:
The command:
"system default switchport shutdown" is not in the Nexus 3000 interface configuration documentation. However I did find it in the Nexus 7000 interface configuration guide.  I would like to have it added to the N3k interface configuration guide.

Here is the URL for N3K Command Reference:
http://www.cisco.com/en/US/docs/switches/datacenter/nexus3000/sw/command/reference/5_0_3/interfaces/3k_cmd_ref_if_cmds.html#wp1082688

Here is the URL for N7K Command Reference:
http://www.cisco.com/en/US/docs/switches/datacenter/sw/6_x/nx-os/interfaces/command/reference/if_commands.html#wp1064988

Below is copied and paste from a N3K:
N3K(config)# system default switchport ?
  <CR>      
  shutdown  Configure admin state

N3K(config)# system default switchport

Conditions:
Applies to all command reference for N3k
