IEEE 802.1Q VLAN Multiple networks share the same link

IEEE 802.1Q (also known as VLAN Tagging) was a project in the IEEE 802 standards process to develop a mechanism to allow multiple bridged networks to transparently share the same physical network link without leakage of information between networks.

Someone knows how do that in QNX 4.25 and QNX 6?


i think you need to initialize another tcp/ip stack, check chapter “Running multiple instances of the TCP/IP stack”.

With qnx6:

ifconfig vlan0 create

ifconfig vlan0 vlan 1234 vlanif en0

ifconfig vlan0 up


and again i learned something new :stuck_out_tongue_winking_eye:

thanks. I am going to try that and say you
