S5212F Switch Vlan for mgmt interface

Hi I try to put the mgmt Interface of an S5212F Switch in a vlan.

The interface vlan 30 exists

theoretically it should work like this

OS10# configure terminal
OS10(config)# interface mgmt1/1/1
OS10(conf-if-ma-1/1/1)# switchport mode access

The answer is

% Error: Unrecognized command.

When  I do the same for a normal interface  it works fine

what do I wrong?

thanks and reagrds
