Learn how to create a VMkernel adapter on a host that is associated with a distributed switch to provide network connectivity to the host and to handle the traffic for vSphere vMotion, IP storage, Fault Tolerance logging, vSAN , and others. I’m using vSphere 7. In the . 1. The VMkernel should not be created/connected to a standard switch(VSS) port group which is already connected to a VM. ; When a new uplink is in use for the dVswitch, ensure you have network connectivity to the uplink with the same or relevant VLANs trunked through. In your virtual environment, a vSphere Standard Switch handles VMkernel adapters for vSphere vMotion and for the management network, and virtual machines grouped. I doed it 2-times before, it puts vmkernel to local switch portgroup, mover uplink to local switch and destroys all vDS info. If you are not comfortable with the performance, you can Indeed, the MTU change simply caused a mini network outage when reconfiguring your standard virtual switch. Check that the enhanced VMXNET adapter is connected to a standard switch or to a distributed switch with jumbo frames enabled. Show More Show Less. PowerCLI can take away a lot if not all of the effort. 5. For example, VMkernel adapter vmk2 is used for Enable jumbo frames on a VMkernel adapter by changing the maximum transmission units (MTU) of the adapter. If you select the vMotion or the Provisioning TCP/IP stack, you will be able to use only these stacks to handle vMotion or Provisioning traffic on the host. from the . If a VMkernel adapter is configured to use DHCP, the custom TCP/IP stack can be set to use the DNS settings that the DHCP server hands out. If you select the vMotion or the Provisioning TCP/IP stack, you can use only this stack to handle vMotion or for Provisioning traffic on the host. Pre-requisites: Ensure that the dvPortGroup (s) used for the vmkernel or service console are configured to match the existing port group configuration on the standard switch (VLAN, Nic Teaming). On an ESXi host, each pnic has one associated uplink adapter. vSwitch0 is assigned to vmnic0 Under "Networking" highlight VMkernel Adapters; Choose the old vmk (vmk2 in this sample) and click Edit (pencil icon) Remove the check mark next to vSAN - this disables vSAN traffic on the original VMK; Verify all VMs are in an accessible state - this is precautionary, the expectation is that no VMs will be affected. 1 and later. tab, expand . vSphere Networking. Make sure that you leave at least one VMkernel adapter for management traffic on the host to keep the network connectivity up. Select the destination standard switch from the list. To see more details about the hosts, expand the network Update: after some further testing (also with the esxcfg-vmknic command) I discovered that you apparently can't "modify" the MTU of an existing VMkernel vNIC.
