dos-protection
echo-chargen
This command protects against DoS echo/chargen attacks in which the
echo service repeats anything sent to it, and the chargen (character
generator) service generates a continuous stream of data. When used
together, they create an infinite loop and result in a denial-of-service. Use
the
no
form to disable this feature.

smurf
This command protects against DoS smurf attacks in which a perpetrator
generates a large amount of spoofed ICMP Echo Request traffic to the
broadcast destination IP address (255.255.255.255), all of which uses a
spoofed source address of the intended victim. The victim should crash due
to the many interrupts required to send ICMP Echo response packets. Use
the
no
form to disable this feature.
