•     
Denial of Service L4 Port
. Enable or disable this option by selecting the appropriate 
radio button. Enabling L4 Port DoS prevention causes the switch to drop packets that 
have TCP/UDP source port equal to TCP/UDP destination port. The factory default is 
Disable.
•     
Denial of Service ICMP
. Enable or disable this option by selecting the appropriate 
radio button. Enabling ICMP DoS prevention causes the switch to drop ICMP packets 
that have a type set to ECHO_REQ (ping) and a size greater than the configured 
ICMP packet size. The factory default is Disable.
•     
Denial of Service Max ICMP Size
. Specify the Max ICMP packet size allowed. If 
ICMP DoS prevention is enabled, the switch will drop ICMP ping packets that have a 
size greater then this configured Max ICMP packet size. The factory default is 512 
bytes.
