set to 1, and the payload length is smaller than 1240. By default, this option is
disabled.
Denial of Service ICMP Fragment. Enabling ICMP Fragment DoS prevention
causes the switch to drop fragmented ICMP packets. By default, this option is
disabled.
Denial of Service Smurf. Enabling Smurf DoS prevention causes the switch to drop
broadcast ICMP echo request packets. By default, this option is disabled.

drop packets with a source IP address that is equal to the destination IP address. By
default, this option is disabled.
Denial of Service SMAC=DMAC. Enabling SMAC=DMAC DoS prevention causes
the switch to drop packets with a source MAC address that is equal to the destination
MAC address. By default, this option is disabled.

TCP Fragment DoS prevention causes
the switch to drop packets with a TCP payload for which the IP payload length minus
the IP header size is smaller than the minimum allowed TCP header size. By default,
this option is disabled.
Denial of Service TCP Offset. Enabling
TCP Offset DoS prevention causes the
switch to drop packets with a TCP header offset of 1. By default, this option is
disabled.
Denial of Service TCP Port. Enabling
