There was some pain my neck those days, that I found my 6506 sent a lot of ARP broadcast to address: 192.168.1.123(For security reason, I changed the address), but in fact, this address was not existence! It must be some one made this mistake, some one type a wrong address but didn't notice. It was unreasonable for 6506 sent so many broadcast. So I would like to check the real source of this data flow, how should I do?
Thanks a lot!
