    How many vlans can i create in a Fedora Machine?

    One more question. Is it hardware dependant or operating system dependant.

    Why i am asking because i have dual core's, quad core and core2duo machines.

    Expecting some good replies

    As VLANs are created over minor-devices in Linux, the limit should be 256 VLANs per ethernet adapter.
    Edit: You have to count in that devices like tun/tap, loop are minor devices of an ethernet adapter. So you can have 256 minor devices in total, but most likely not 256 Vlan devices as you need/want other ones, too.
