[Ethernet] Create 2 logical network with 1 physical interface   
Hello
I want to have 2 logical network interfaces, with the physical interface en0 .

How can I do it ?
Have I use "ifconfig create" ?


for exemple : 
en0.0 : 192.168.0.1:255.255.255.0
en0.1 : 10.0.0.1:255.0.0.0

Thanks

The closest thing sounds like a vlan.

# ifconfig vlan0 create
# ifconfig vlan0 vlan 1234 vlanif en0
# ifconfig vlan0 10.0.0.1/8

# ifconfig vlan0 create
ifconfig: SIOCIFCREATE: Invalid argument

What version of the stack are you running?  Does
'ifconfig -C' list vlan?

'ifconfig -C' return nothing ...

# ifconfig -C

I suspect you're running an old stack.  The 6.3.2
npm-tcpip-v[46].so should both support vlan.

Re: [Ethernet] Create 2 logical network with 1 physical interface   
ok.
How can I change the stack ?
Currently, I use QNX 6.2.1

You can try npm-tcpip-v6.so if you have it.  IIRC it
always supported vlan.

# slay io-net
# io-net -p /lib/dll/npm-tcpip-v6.so ...

Or look into getting 6.3.2...

You need to start io-net with the right stack, not inetd.
Check out IONET_CMD in /etc/system/enum/include/net.  When
in doubt you can slay / restart it in /etc/rc.d/rc.local.

Re: [Ethernet] Create 2 logical network with 1 physical interface   
And how can I have documentation of the stacks ?

In the system docs (helpviewer).

QNX Neutrino RTOS
  Utilities Reference
    N
      npm-tcpip-v6.so
