Why numerous ARP's from 0.0.0.0 or 169.X.X.X


S4 cores show repeated messages--(approx.5-10/sec) of "Recieved ARP on vlan XXXX but there is no path to the sender IP address 0.0.0.0 (or 169.x.x.x )" Campus environment with 5000+ pc's Is this normal behavior of MS pc's when they boot before they do DHCP? Is this rate harmful? Can it be eliminated?
thnks in advance

Hi Walt, it seems normal as it is reported often and it is not harmful.
This article explains the error and how to stop it from being printed in the logs.
