    Hi, i'm trying to configure an net adapter with two Vlan on it but i have no VIOS.

    Is it possible without having to install one ?
    I've got no access to mkvdev and "lsdev -virtual" .

    I'm using AIX 5.3.

    Thanks in advance.

    You only need a VIO server if you want those Virtual Ethernet adapters to have connectivity to a physical network through a Shared Ethernet Adapter,

    As long as you don't need that, you should be good to go.

    To add a Virtual Ethernet adapter, you'll need the approprate hardware to do so, which usually would be any Power 5 class system with an HMC attached. You must have the HMC to "create" a virtual ethernet interface on your LPAR.
    Hope this helps.

    please could you explain me a little the way to configure it?
    Actually, i'm trying to use my AIX box for routing vlans with only one physical network adapter.

    I tryied using "smit vlan", when i add a vlan id, it create a enXX network adapter for each vlan i add.
    So i was thinking that it was abble to share the real network between vlans .

    If you just want to add a virtual adapter to a real ethernet Port, that is assigned to your LPAR, you are perfectly right with "smit vlan". However, the VLAN also has to be configured on the switch. Perhaps this is the missing link.

    To use the VLAN option you also need to configure the hypervisor (as virtual ethernet switch) and add the VLAN identifer that you want to use.

    However, what is probably easier, is to have one partition with the physical adapter, and just use that adapter as is. With the managed system you create one virtual adapter using a different PVID in the other clients - not because it is needed, but because it makes documentation a bit easier.
    The partition with two adapters (one physical, one virtual) is not bridging the virtual adapters to the physical adapter (as a VIO server can, as a SEA or Shared Ethernet Adapter). Instead, this partition can route. However, this will require that the partitions without a physical adapter will need to be in a separate IP network, or the routing will not work for any system in the same network but accessible only via the physical network, and v.v.

    In other words, you can probably accomplish what you want to do without any usage of IEEE 802.Q, and regardless of using VLAN or not, you will need multiple IP networks when you route rather than bridge the virtual adapters to the physical adapters.

    But i now succeed routing the vlan with my AIX box (with only one physical network card and without any VIOS).
    I just used "smit vlan" and added one, it created a new enX adapter (checked by using lsdev -t en before and after) and by doing a "ifconfig enX address mask up"
    and a "smit route" to verify and/or modify routes.
    Of course, the switch port must in trunk mode.
    So, i want to thank you all for helping me.
    We may consider this post resolved.
    Best Regards.
