    Allan,

    Years ago big-ip had no trunking support. A year or two ago,
    we added support for vlan tags in a rudimentary way (only
    on "internal" interfaces).
    As of 4.0, which shipped last spring, we have full vlan
    trunking support for all network traffic.

    Regards,
    Rick Masters

    Hello Tim,

    The last time we looked at the Big IPs they did not support 802.1q,
    which is one of the reasons we opted not to deploy them. I know there
    are some good F5 guys on this list, so they may correct me, but I am
    pretty sure they didn't support it (we have the same problem, we use
    CAT 6509s in the core of our data center, and because of our design we
    needed to be able to support trunking).

    Hope this helps.
