    From the docs,

    Receive Errors: The number of input errors encountered on this device. This is a counter for unsuccessful reception due to hardware/network errors.

    Is this the only device seeing the issues? Start with the NIC, cables and network port. If there are more than 1 device seeing issues, start with the other end.

    This is running on a JS22 blade. No other blades are showing any errors and the nortel switch is not reporting any errors.

    Okay, I've no direct experience of the JS22's. Is there a single instance of AIX on this blade, using the entire ethernet adapter? Is there anything in errpt? Can you run diags against the IVE?

    you set the media_speed attribute of ent0 incorrectly
    try switching it
    lsattr -Rl ent0 -a media_speed
    tells you the possible values - check them with your network admin

    Don't they usually show up as collisions in that instance?

    no.
    however, normally you have late collisions when media_speed is setup incorrectly.
