Restrictions and Precautions

Restrictions and Precautions

This section describes the restrictions and precautions for you to know when configuring intrusion prevention.

Learn about the following items before the configuration:

  • If a signature has been removed from the latest IPS signature database after an update, all configurations associated with this signature cease to take effect.

  • In a per-flow load balancing deployment, intrusion prevention is supported but with a lower detection rate than in active/standby mode.

  • Intrusion prevention may function improperly if the forward and return paths of packets are different.

  • If the Central AP is deployed between two routers, and the routers detect each other through BFD, you are advised to properly prolong the BFD time (longer than 100 ms is recommended) to prevent BFD flapping resulting from occasional network congestion.
