Usage Guidelines

A network often undergoes ICMP packet attacks. If a switch receives a large number of broadcast ICMP request packets on user-side interfaces, these packets are sent to the switch CPU for processing. Then the CPU usage becomes high, affecting other services on the switch. You can use the icmp rate-limit command to prevent the switch from being attacked by ICMP packets.

After you run the icmp rate-limit enable command in the system view or interface view, the device limits the rate of ICMP packets by the default rate limit.

You can then run the icmp rate-limit command in the system view or interface view to configure a rate limit for ICMP packets.

Example

# Enable the rate limit function for ICMP packets.

<Huawei> system-view
[Huawei] icmp rate-limit enable
