Creating a VMkernel interface on a vSphere Standard Switch
A VMkernel port group is created when there is a need to create a VMkernel network interface (VMK). It is used for iSCSI, NAS, and vMotion.
There can only be one VMkernel port per subnet. Although it doesn't stop you from creating multiple VMkernel ports per subnet, it will only use one of them. Usually, the VMkernel port that was first created is used. VMkernel traffic can be routed, although this is not recommended for vMotion, as it can cause latency issues. The VMkernel gateway IP address should also be in the same subnet.
Note
Only one VMkernel default gateway can be configured on an ESXi host.
How to do it...
The port group can be created either from the vSphere Web Client GUI or by using the esxcfg-vswitch and esxcfg-vmknic commands.
Using vSphere Web Client
The following procedure explains how to create a VMkernel port group by using a vSphere Web Client:
Select the ESXi host from the inventory and navigate to Manage | Networking...
