Description
Enable or disable this option by selecting the corresponding line on the
pulldown entry field. Enabling TCP Flag DoS prevention causes the
switch to drop packets that have TCP flag SYN set and TCP source port
less than 1024 or TCP control flags set to 0 and TCP sequence number
set to 0 or TCP flags FIN, URG, and PSH set and TCP sequence
number set to 0 or both TCP flags SYN and FIN set. The factory default
is disabled.
Enable or disable this option by selecting the corresponding line on the
pulldown entry field. 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 disabled.
Enable or disable this option by selecting the corresponding line on the
pulldown entry field. 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 Pkt Size. The factory default is
disabled.
Specify the Max ICMP Pkt 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 Pkt Size. The factory default is disabled.
