    I need to lock down the bandwidth awailable to one port of a 3550. I
    understand the bandwidth command is present but non functional on the
    3550 but have not been able to have the port get any slower during

    I'm trying to use 8000 bits per second to test and then increase the
    bandwidth once I've proved the configuration is working.

    None of the outputs below register any packets hitting the policy.

    Any help appreciated

    I don't know if you can rate-shape on a 3550, I believe you need a router to
    do this. But if you can, you can't do this while the port is configured as
    a VLAN interface. You need to assign the port an IP address so that it
    functions as a router port.
