DoS
Spoofing attack
1. The soure ip is same as switch's
interface ip but the source mac is different
2. Source ip is the same as the switch's IP
in ARP packet
3. Self IP packet dected
Possible spoofing attack from (IP: <ipaddr>
MAC: <macaddr> Port: <portNum>)
Critical
The DoS attack is blocked
<dos_name> is blocked from (IP: <ipaddr>
