Configuring CPU Attack Defense

Configuring CPU Attack Defense

With the CPU attack defense function, the device limits the rate of packets sent to the CPU to protect the CPU.

Pre-configuration Tasks

Before configuring CPU attack defense, complete the following tasks:

  • Connect interfaces and set physical parameters for the interfaces to ensure that the physical status of the interfaces is Up.
  • Configure an ACL for blacklist, if necessary.

Configuration Process

Before configuring CPU attack defense, create an attack defense policy. The other tasks can be performed in any sequence and can be selected as required. An attack defense policy takes effect only after it is applied to an object. There is no limitation on when the attack defense policy is applied.
