Configuring Traffic Suppression for ICMP Packets

Configuring Traffic Suppression for ICMP Packets

Context

Attackers may send a large number of ICMP packets to attack a network. Processing all these ICMP packets will occupy many CPU resources and cause service abnormalities. To resolve this problem, configure ICMP packet suppression.

After ICMP packet suppression is configured on an interface, the system automatically discards ICMP packets when the number of ICMP packets sent by an interface to the CPU every second exceeds the rate threshold.

Pre-configuration Tasks

Before configuring traffic suppression for ICMP packets, configure link layer protocol parameters for interfaces to ensure that the link layer protocol status on the interfaces is Up.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run undo icmp rate-limit disable

    Traffic suppression for ICMP packets is enabled.

    By default, the traffic suppression function for ICMP packets is enabled.

  3. Run icmp rate-limit [ interface interface-type interface-number1 [ to interface-number2 ] ] threshold threshold-value

    The rate threshold for ICMP packets is configured.

    By default, the rate limit for ICMP packets is 1500 pps.

  4. Run commit

    The configuration is committed.
