    Hi all,

    I have a curious problem. I installed a CE card (ce1) and configured it to
    use three different VLANs. 247,248,249. All of the 249 stuff seemed to
    work; however, the communications to the other VLANs did not. ifconfig
    reveals

    ce249001
    ce248001
    ce247001

    all configured with the proper IP addresses, gateways and subnet masks.

    >From a switch perspective...they are CISCO 3500 series switches (5 of them).
    The trunk ports have been setup for 802.1q between the switches and the
    ports for this sun server is also setup as a 802.1q trunk. I also have a
    Windows box which also was setup for VLAN tagging and it seemed to work OK
    across all three VLANs. So I am pretty sure that my switch configuration is
    setup properly. (Not 100% sure but pretty sure).

    Because we were making the change to a production environment, I needed to
    rollback the changes. I am going to try again in a few weeks but I would
    like to armed with a little more information than the one pager that sun
    provides with their documentation.

    Any thoughts and will summarize.

    Marco
