How To Configure Static VLANs in QNX

Can any one please tell me How To Configure Static VLANs in QNX as there is no vconfig command like Linux.

BSD put everything into ifconfig.

ifconfig vlan0 create
ifconfig vlan0 vlanif en0 vlan 0x1234

Thanks… It is working with slight modification like

ifconfig vlan0 vlanif en0 vlan 0x1234 is not working due to incorrect order but

ifconfig vlan0 vlan 0x1234 vlanif en0 is working.

Many thanks…
