Format

anti-attack flood { arp | dhcp | dhcpv6 | igmp | mdns | nd | other-broadcast | other-multicast } sta-rate-threshold sta-rate-threshold

Usage Guidelines

Usage Scenario

After the flood detection function is enabled, you can set the broadcast traffic threshold.

When the traffic rate exceeds the threshold, the device considers a flood attack from the STA and discards the traffic. This prevents the upper-layer network from being affected by the flood.

If the flood blacklist function is enabled using the anti-attack flood blacklist enable command, the device adds flood STAs to the blacklist.

Prerequisites

The flood detection function has been enabled using the undo anti-attack flood disable command.

Example

# Set the DHCP flood threshold to 100 pps.
