    Hi Paul,

    I'm not sure you can filter this - best bet is probably to track down
    what's causing the alerts and see if you can fix that; have a look at
    the two mac addresses which have been associated with the ip address
    and try to figure out what they are and why they're claiming to be the
    right mac for the ip address... If you've changed some kit or whatever
    (eg moved a virtual ip address between different servers, where the
    virtual ip address becomes assigned a different mac eg the card's
    burnt-in address (bia)) you may want to stop/start the sensor
    generating the alerts as it could still be using an internal table
    based on a previous mac/ip match...
