Introduction

A connectivity test checks the reachability between two objects (such as a VM and an IP address) in a network topology. IPv4 and IPv6 protocols are supported. Packets are sent from the source object to the destination object to quickly identify the network failure (such as an unreachable route or firewall blocking).

Constraints and Restrictions

• The source and destination objects must be in the same resource pool. To test the connectivity between objects in different resource pools, add the corresponding resource pools to a communication domain first.

• The destination object must be an IP address. You cannot directly select a VM. (You need to manually enter the VM's internal IP address.)

• Only one connectivity test can be initiated at a time. Wait for a test to complete before initiating the next one.

Prerequisites

• The resource pool to which the source and destination objects belong is running normally.

• The IP address (IPv4 or IPv6) of the destination object has been obtained, and the IP address has been assigned to a VM or network device.

• To test the connectivity to an IPv6 address, the resource pool must support IPv6 network configuration.

Precautions

• Before the test, confirm that the ICMP protocol is enabled (not blocked by the firewall) for the source object. Otherwise, the test result will be "unreachable".

• If the test fails, check the routing configuration and security group rules, then test again.

Steps

Step 1.Go to Networking > Topology and click Test Connectivity. The Test Connectivity page appears.

Step 2.Configure the following fields:

Step 3.Click Start. The system will initiate the test and display the result (reachable or unreachable).

Step 4.View the test result. If the destination object is unreachable from the source object, check the network configuration as prompted. After the test is complete, click Close.
