Possibly: This MAC Flooding is an ARP Cache Poisoning technique aimed at
network switches. When certain switches are overloaded they often drop
into a "hub" mode. In "hub" mode, the switch is too busy to enforce its
port security features and just broadcasts all network traffic to every
computer in your network.

Iâve just found the old SQL-slammer again in my customer network and
notice something that Iâve never notice before:
The worm sends UDP packet using 1 static spoof source IP and 1 static
spoof dest IP, but the MAC address changes in every packet (mostly the
source mac). What is happening here?? Have anybody notice this
