RB1100AHx2 and Atheros 8327 switch-chip issue

Hello.

We just bought RB1100AHx2 and got some problems. First is that winbox.exe doesn’t show vlan-header option, which we can see in:

Flags: I - invalid 
 #   NAME                                           SWITCH                                    VLAN-MODE VLAN-HEADER   
 0   lan172                                         switch2                                   disabled  leave-as-is   
 1   ap65                                           switch2                                   disabled  leave-as-is   

/interface ethernet switch port pr

Second, how to configure trunk port on switch-chip.

Sorry for my pure english.
