Overview of Diagnosis Center

This section describes the definition and objectives of the diagnosis center.

The diagnosis center provides IPSec diagnosis, web page diagnosis, packet tracing, ping, tracert, and diagnosis information collection.

IPSec diagnosis falls into the following types:
- Data stream: diagnoses the data flow protected by IPSec policies.
- Interface: diagnoses the interface on which IPSec policy is applied.
- IP address: diagnoses the peer IP address of the IPSec tunnel.
Web page diagnosis: provides diagnosis information about failures in web page access.
Packet tracing: packet tracing identifies the path a packet takes.
Ping: the most common debugging tool for testing IP connectivity. It uses the ICMP (ICMP6 for IPv6) echo message to determine:
- Whether the remote device is available.
- The round trip delay of messages.
- Packet loss.
Tracert: traces the gateways along the path from the host that sends the data to the destination.
Diagnosis information: provides information about the clock, version, and configuration of the device.

You can use the diagnosis center when faults occur on the device.

Use IPSec diagnosis to locate and rectify faults when IPSec services are interrupted.
Use web page diagnosis to locate and rectify faults when intranet users fail to access web pages.
Use packet tracing identifies the path of the packet takes.
Use ping to check network connectivity.
Use tracert to check network connectivity and locate network faults.
Use diagnosis information to collect information about the operating status and configuration of each module on the device. When a fault occurs, export the diagnosis information and send it to Huawei technical support personnel for fault location.
