Configure the attack of the IPv4&6 packet with the incomplete TCP protocol header smaller than 20 bytes

Configure intercepting the IPv4&6 attack with TCP FIN, URG, and PSH as 1, but sequence as 0

Configure intercepting the IPv4&6 packet with TCP SYN and FIN flags set at the same time

note


  • The software attack detection function is valid only for the packet to the local device; the hardware attack detection function is valid for all the packets received by the switching port.
  • The software attack detection supports the statistics and log recording for the dropped packers; the hardware attack detection is realized by the switching chip and does not support the statistics and log recording for the dropped packets.
