Verify that virtual machine communication is operational and that virtual machines residing on different ESXi hosts can communicate with each, using the ping command.

About this task

Ensures that the virtual network interfaces are up on the hosts and can carry traffic, and that the physical network has correctly configured IGMP for hybrid replication mode.

Expected Outcome

Virtual machines in VXLAN can communicate with each other while residing on separate hosts.

Procedure

  1. Log in to vCenter Server by using the vSphere Web Client.
    1. Open a Web browser and go to https://sfo01m01vc01.sfo01.rainpole.local/vsphere-client.
    2. Log in using the following credentials.

      Setting

      Value

      User name

      administrator@vsphere.local

      Password

      vsphere_admin_password

  2. On the vRealize Log Insight appliances, run the ping command to verify the communication to other VMs in the VXLAN network.
    1. From the Home menu, select Hosts and Clusters.
    2. Expand the entire sfo01m01vc01.sfo01.rainpole.local tree.
    3. Right-click the sfo01vrli01a virtual appliance and select Open Console.
    4. Press ALT+F1 to switch to the command prompt.
    5. Log in using the following credentials.

      Setting

      Value

      User name

      root

      Password

      vrli_root_password

    6. Run the following command.

      Command

      Remarks

      ping sfo01vrli01b.sfo01.rainpole.local

      ping from sfo01vrli01a to sfo01vrli01b

      ping vrops01svr01b.rainpole.local

      ping from sfo01vrli01a to vrops01svr01b

      Note:

      The test assumes that appliances are running on separate hosts.

What to do next

If you encounter issues while performing this procedure, use the following troubleshooting tips:

Troubleshooting Tips

  • Move the VMs to the same host, and if ping is successful, move back to separate hosts.

  • Change transport zone and virtual wires to unicast, and if ping is successful, IGMP is not correctly configured on the physical network.
