Storm-Control Command issue on N1500 Series / Firmware 6.6.0.2

Hi guys,

the last 5 years I was working with Cisco switches and know we are testing Dell networking switches.
I have a N1548P and a N1524P in a stack. I configured an access interface with the following commands:

interface gi1/0/14

storm-control broadcast level 10
storm-control broadcast action shutdown
spanning-tree portfast
switchport access vlan 903

When I add storm-control broadcast action trap, It replaces the shutdown command:

interface gi1/0/14

storm-control broadcast level 10
storm-control broadcast action trap
spanning-tree portfast
switchport access vlan 903

On Cisco Switches I can add both:
storm-control broadcast level 0.30 0.20
storm-control multicast level 0.20 0.10
storm-control action shutdown
storm-control action trap

Do you have any idea?
