![]() Step 3: Perform a reverse link test by using ping and mtr Then, perform link tests and record the test results. Set the destination address to the domain name or IP address of the destination server. Use WinMTR or mtr based on the operating system of your client.We recommend that you ping at least 100 packets and record the test results. Perform continuous ping tests on the destination server domain name or IP address from the client.Perform the following tests on the the destination server from the client: Step 2: Perform a forward link test by using ping and mtr Procedure Step 1: Obtain the public IP address of the local networkĪccess ip. in the local network of the client to obtain the corresponding public IP address. Scenario 2: Internet control message protocol (ICMP) rate limiting.Scenario 1: Inappropriate network configurations of the destination host.For more information about the tools used for link tests, see Other considerations. If a packet loss or failure occurs when the ping command is used, you can refer to the following operations to perform a link test. If you have authorized or submitted security information such as the logon account and password in the Alibaba Cloud Management Console, we recommend that you modify such information in a timely manner.If you modify the configurations and data of instances including but not limited to ECS and ApsaraDB RDS (RDS) instances, we recommend that you create snapshots or enable RDS log backup.Before you perform operations that may cause risks, such as modifying instance configurations or data, we recommend that you check the disaster recovery and fault tolerance capabilities of the instances to ensure data security. ![]() This topic describes how to use tools to perform link tests and analysis. ![]() ![]() If a packet loss or failure occurs when the client accesses the destination server by using the ping command, the Trace Route (tracert) or My traceroute (mtr) tool can be used to perform link tests to determine the root cause of the problem.
