Which Command Can Be Run To Troubleshoot Connectivity Problems With Vmkernel Network Interfaces

Testing VMkernel network connectivity with the vmkping command (1003728) For troubleshooting purposes, it may be necessary to test VMkernel network connectivity between ESXi hosts in your environment.

You can see VMkernel interfaces clearly when looking at a host’s networking configuration: Looking at the properties of the VMkernel portgroup you can see what type of traffic the vmk interface is being used for: You can test management network connectivity using the ‘Test Management Network’ option available in the DCUI.

You can test management network connectivity using the ‘Test Management Network’ option available in the DCUI. This can be useful to test management connectivity following installing ESXi.

What is the use of Vmkping?

vmkping uses a VMkernel’s TCP/IP stack to send ICMP traffic to a destination host.

What is VMkernel?

VMkernel is a POSIX (Portable Operating System Interface)-like operating system (OS) developed by VMware. It acts as a liaison between virtual machines (VMs) and the physical hardware that supports them, such as ESXi hosts. A VM needs VMkernel to communicate with the ESXi server.
