1072undo rst-flood detect { ip ipv4-address | ipv6 ipv6-address } [ vpn-instance vpn-instance-name ]DefaultIP address-specific RST flood attack detection is not configured.ViewsAttack defense policy viewPredefined user rolesnetwork-adminParametersip ipv4-address: Specifies the IPv4 address to be protected. The ipv4-address argument cannot be255.255.255.255 or 0.0.0.0.ipv6 ipv6-address: Specifies the IPv6 address to be protected.vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the protected IPaddress belongs. The vpn-instance-name argument is a case-sensitive string of 1 to 31 characters.Do not specify this option if the protected IP address is on the public network.threshold threshold-value: Specifies the threshold for triggering RST flood attack prevention. Thevalue range is 1 to 1000000 in units of RST packets sent to the specified IP address per second.action: Specifies the actions when an RST flood attack is detected. If no action is specified, theglobal actions set by the rst-flood action command apply.client-verify: Adds the victim IP addresses to the protected IP list for TCP client verification. If TCPclient verification is enabled, the device provides proxy services for protected servers.drop: Drops subsequent RST packets destined for the protected IP address.logging: Enables logging for RST flood attack events.none: Takes no action.Usage guidelinesWith RST flood attack detection configured for an IP address, the device is in attack detection state.When the sending rate of RST packets to the IP address reaches the threshold, the device entersprevention state and takes the specified actions. When the rate is below the silence threshold(three-fourths of the threshold), the device considers returns to the attack detection state.Examples# Configure RST flood attack detection for 192.168.1.2 in the attack defense policy atk-policy-1. system-view[Sysname] attack-defense policy atk-policy-1[Sysname-attack-defense-policy-atk-policy-1] rst-flood detect ip 192.168.1.2 threshold2000Related commandsrst-flood actionrst-flood detect non-specificrst-flood thresholdrst-flood detect non-specificUse rst-flood detect non-specific to enable global RST flood attack detection.Use undo rst-flood detect non-specific to disable global RST flood attack detection.
