H3C MSR Series Command Reference

1089
ipv6 ipv6-address: Specifies the IPv6 address to be protected.
vpn-instance vpn-instance-name: Specifies the MPLS L3VPN instance to which the protected IP
address 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 UDP flood attack prevention. The
value range is 1 to 64000 in units of UDP packets sent to the specified IP address per second.
action: Specifies the actions when a UDP flood attack is detected. If no action is specified, the global
actions set by the udp-flood action command apply.
drop: Drops subsequent UDP packets destined for the protected IP address.
logging: Enables logging for UDP flood attack events.
none: Takes no action.
Usage guidelines
With UDP flood attack detection configured for an IP address, the device is in attack detection state.
When the sending rate of UDP packets to the IP address reaches the threshold, the device enters
prevention state and takes the specified actions. When the rate is below the silence threshold
(three-fourths of the threshold), the device returns to the attack detection state.
Examples
# Configure UDP flood attack detection for 192.168.1.2 in the attack defense policy atk-policy-1.
