    why macmnsvc.exe broadcast to all client? and the node will be disconnected (portsecurity enable on the switch)


      hi everybody .Two of my client reported about discooneting several time a day. I used  Wireshark to view what happen and it was  all about ARP.  then i considered  that  macmnsvc.exe(mcAfee agent 5.0.4) broadcast to all client in own subnets  as  if  ARP poisening happens .

      I ask my network expert and they  said we enable portsecurity on the switch so that  the switch thought it is  an attack and  disconnect the node .

      so I uninstall  all McAfee product  and the problem of disconnecting  solved .

      how do i do and why the agent broadcast to all client in the subnet?
