Learning Vlan- Basic Questions



  • Hi
    I decided to try to get the Intel ATOM D945GCLF board to work witha VLAN. I am very new at these things and I tried to understand
    all the available info on VLANS but I am stuck because I don't have
    much knowledge on this. Basically since the Realtek chip NIC is not supported, I would like to learn how to use a Vlan Switch to accomplish
    the same as if there were 2 NICS that could work on this board.

    Here is my configuration
    1. Atom Board with intel  82541P1 PCI lan card
    2. ASUS QX1024 P smart switch
    3. Port 26 Vlan tag 2
    5. Default Vlan 1..26 (cannot be changed or edited)
    I then enabled VLAN on the Asus switch via its software.

    I attached the atom board to port #1 and my pc to
    port #2 on the Switch.
    I configured Pfsense that WAN is EM0 Interface vlan tag 2

    On my PC, I could get an IP from pfsense and access pfsense
    web configurator.

    I then attached the ADSL modem to  port#26 (vlan tag 2)

    so I am lost at this point, Pfsense does not show any IP at
    port #26 and also there is no Link Status when I plugged it into
    Port #26 . The link status light comes on only when
    I plugged the Adsl modem onto port 1..23.

    So I am definitely missing some basic config here, must I
    perform some more specific settings on the ASUS switch
    or do I need some specific configs on Pfsense?

  • Could you please verify that your switch is a "ASUS QX1024 P smart switch"?
    Can you provide a datasheet to it?
    Because the only ASUS switch with a similar name i can find is a "ASUS GigaX 1024P" and this switch is not 802.1Q capable.

    Hi
    yes you are right, I it only support 802.1P so I guess this is the problem.. Lemme go change it to
    something that has a specific Certification of 802.1Q on it.

  • If the switch were ASUS GigaX 1024P then it's a bit confusing. Although the spec sheet doesn't say anything about .1Q but it does support .1Q, tag-base and/or port-base vlans.

    Eagleeye, you may want to configure your ASUS switch correctly, via CNM. Check your CNM manual, pp35, 4.7.5 VLAN setup.
