Troubleshooting Roadmap

Troubleshooting Roadmap

There are two IPSec fault symptoms: IPSec tunnel setup failure and abnormal services after successful IPSec tunnel setup.

Figure 26-1 shows the IPSec troubleshooting roadmap.

IKE SA or IPSec SA negotiation failure is the core issue in IPSec faults. You can carry out in-depth analysis on the IKE negotiation process of IPSec Tunnel Setup Failure. Usually, other IPSec faults are caused by incorrect feature configurations, such as interfaces, Access Control Lists (ACLs), routes, and network address translation (NAT). Such faults need to be processed based on the specific scenario.

During routine maintenance or after receiving a fault report, a network administrator can find the troubleshooting guidance by referring to Figure 26-1. For complex faults, the network administrator can analyze triggering causes layer by layer based on the fault symptom and IPSec Working Principles to find the root cause. Understanding the overall troubleshooting roadmap helps network administrators quickly locate and process faults.

The following lists two IPSec fault trees: IPSec tunnel setup failure and abnormal IPSec services.
