Before You Start

Before You Start

Before configuring IPSec functions, familiarize yourself with the usage scenario, complete the pre-configuration tasks, and obtain the data required for the configuration. This will help you complete the configuration task quickly and accurately.

Usage Scenario

On the Internet, most data is transmitted in plain text, causing security risks. For example, bank accounts and passwords may be intercepted or tampered with, user identities may be counterfeited, or bank networks may be attacked. IPSec can protect transmitted IP packets to reduce the risk of information leaks.

Pre-configuration Tasks

Before configuring IPSec, complete the following tasks:
  • Configure the physical parameters for the interface and ensure that the physical layer status of the interface is Up.

  • Configure the link layer parameters for the interface and ensure that the link layer protocol status of the interface is Up.

Data Preparation

To configure IPSec, you need the following data.




Names of the IPSec proposal


  • Names of the Security Association (SA)

  • Security Parameter Index (SPI)

  • Authentication key

  • Encryption key
