Troubleshooting VMkernel interfaces
In this section, we will see how to troubleshoot VMkernel interfaces. A VMkernel interface is a networking interface used in VMware infrastructure for Fault Tolerance, vMotion and IP storage. In vSphere hosts VMkernel interface is responsible for handling vMotion, network connectivity and IP storage. In this section we will see how to troubleshoot VMkernel interfaces using the following commands:
Confirm VLAN tagging
Ping to check connectivity
Vicfg-vmknic
Escli network ip interface for local configuration
Escli network ip interface list
Add or remove
Set
Escli network ip interface ipv4 get
You should know how to use these commands to test if everything is working. You should be able to ping to ensure connectivity exists.
We will use the vicfg-vmknic command to configure vSphere VMkernel NICs. Let's create a new VMkernel NIC in a vSphere host using the following steps:
Log in to your VMware vSphere CLI.
Type the following command to create a new VMkernel NIC:
vicfg...
