    I have a Cisco 500-24 switch. Port 2 is set forced to 10/half. A
    Cisco router plugs into this link, which has a 10/half ethernet
    connection (doesn't support full.)

    Why does the switch keep throwing up the alert light? Log shows this;

    Port Fa2: Detected a half duplex configuration or a duplex mismatch on
    this link.

    Is there a way to disable this?

    either set both to AUTO or hard code both. dont just hard code one and
    not the other.

    Yes, that's what I said. A device which only supports 10/half is by
    default hardcoded to 10/half. There is no configuration on the router
    for duplex or speed. (Yes, it is an old router.)

    Any idea why the switch is alerting?
