Configure System Information User Manual84
• Denial of Service IPv6 Fragment. Enabling IPv6 Fragment DoS prevention causes
the switch to drop IPv6 packets for which the header is fragmented, the More flag is
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.
• Denial of Service SIP=DIP. Enabling SIP=DIP DoS prevention causes the switch to
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.
• Denial of Service TCP FIN&URG&PSH. Enabling
TCP FIN & URG & PSH DoS
prevention causes the switch to drop packets for which the TCP FIN, URG, and PSH
flags are set to 1 and for which the TCP sequence number is set to 0. By default, this
option is disabled.
• Denial of Service TCP Flag&Sequence. Enabling
TCP Flag DoS prevention causes
the switch to drop packets for which the TCP control flags are set to 0 and the TCP
sequence number is set to 0. By default, this option is disabled.
• Denial of Service TCP Fragment. Enabling
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
TCP Port DoS prevention causes the switch to
drop packets with a TCP source port that is equal to the TCP destination port. By
default, this option is disabled.
• Denial of Service TCP SYN&FIN. Enabling
TCP SYN & FIN DoS prevention causes
the switch to drop packets for which the TCP flags SYN and FIN are set to 1. By
default, this option is disabled.
• Denial of Service TCP SYN&RST. Enabling
TCP SYN & RST DoS prevention
causes the switch to drop packets for which the TCP flags SYN and RST are set to 1.
By default, this option is disabled.
• Denial of Service UDP Port. Enabling UDP Port DoS prevention causes the switch
to drop packets with a UDP source port that is equal to the UDP destination port. By
default, this option is disabled.
