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, and Virtual SAN. You should dedicate a single distributed port group per VMkernel adapter. One VMkernel adapter should handle one traffic type.

Procedure

  1. In the vSphere Web Client, navigate to the host.
  2. Under Manage, select Networking and then select VMkernel adapters.
  3. Click Add host networking.
  4. On the Select connection type page, select VMkernel Network Adapter and click Next.
  5. Select a distributed port group and click Next.
  6. On the Port properties page, configure the settings for the VMkernel adapter.

    Option

    Description

    Network label

    The network label is inherited from the label of the distributed port group.

    IP settings

    Select IPv4, IPv6, or both.

    Note:

    The IPv6 option does not appear on hosts that do not have IPv6 enabled.

    TCP/IP stack

    If custom stacks are available, select one from the list.

    Enable services

    You can enable services for the default TCP/IP stack on the host. Select from the available services:

    • vMotion traffic. Enables the VMkernel adapter to advertise itself to another host as the network connection where vMotion traffic is sent. You can enable this property for only one vMotion and IP storage VMkernel adapter per host. If this property is not enabled for any VMkernel adapter, migration with vMotion to the selected host is not possible.

    • Fault Tolerance traffic. Enables Fault Tolerance logging on the host.

    • Management traffic. Enables the management traffic for the host and vCenter Server. Typically, hosts have such a VMkernel adapter created when the ESXi software is installed. You can create another VMkernel adapter for management traffic on the host to provide redundancy.

    • Virtual SAN. Enables the Virtual SAN traffic on the host. Every host that is part of a Virtual SAN cluster must have such a VMkernel adapter.

  7. (Optional) : On the IPv4 settings page, select an option for obtaining IP addresses.

    Option

    Description

    Obtain IP settings automatically

    Use DHCP to obtain IP settings.

    Use static IP settings

    Type the IPv4 IP address and subnet mask for the VMkernel adapter.

    The VMkernel Default Gateway and DNS server addresses for IPv4 are obtained from the selected TCP/IP stack.

  8. (Optional) : On the IPv6 settings page, select an option for obtaining IPv6 addresses.

    Option

    Description

    Obtain IPv6 addresses automatically through DHCP

    Use DHCP to obtain IPv6 addresses.

    Obtain IPv6 addresses automatically through Router Advertisement

    Use router advertisement to obtain IPv6 addresses.

    Static IPv6 addresses

    1. Click Add to add a new IPv6 address.

    2. Type the IPv6 address and subnet prefix length, and click OK.

    3. To change the VMkernel default gateway, click Edit.

  9. Review your setting selections in the Ready to complete page and click Finish.
