In OS 10 switches to convert a 40/100G port to 4x10G SFP+ when connected using 40G to 4x10G DAC cable use:

config t
     interface breakout <interface> map 10g-4x

where <interface> should be replaced with number such as 1/1/15

Refer:

Note: There is also mention of 'feature auto-breakout' in above reference. Perhaps that might do the breakout configuration automatically once the breakout cable is connected.
