You might have to change the supported traffic type for a VMkernel adapter, or the way IPv4 or IPv6 addresses are obtained.

1

In the vSphere Web Client, navigate to the host.

2

Under Manage, select Networking and then select VMkernel adapters.

3

Select the VMkernel adapter that resides on the target distributed or standard switch and click Edit.

4

On the Port properties page, select the services that you want to enable.

Check box

Description

vMotion traffic

Enables the VMkernel adapter to advertise itself to another host as the network connection where vMotion traffic is sent. If this property is not enabled for any VMkernel adapter, migration with vMotion to the selected host is not possible.

Provisioning traffic

Handles the data transferred for virtual machine cold migration, cloning, and snapshot creation.

Fault Tolerance traffic

Enables Fault Tolerance logging on the host. You can use only one VMkernel adapter for FT traffic per 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 was installed. You can have an additional VMkernel adapter for management traffic on the host to provide redundancy.

vSphere Replication traffic

Handles the outgoing replication data that is sent from the sourceESXi host to the vSphere Replication server.

vSphere Replication NFC traffic

Handles the incoming replication data on the target replication site.

Virtual SAN

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

5

On the NIC Settings page, set the MTU for the network adapter.

6

With IPv4 enabled, in the IPv4 settings section, select the method by which IP addresses are obtained.

Option

Description

Obtain IP settings automatically

Use DHCP to obtain IP settings. A DHCP server must be present on the network.

Use static IP settings

Enter 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.

7

With IPv6 enabled, in the IPv6 settings select an option for obtaining IPv6 addresses.

Note

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

Option

Description

Obtain IPv6 addresses automatically through DHCP

Use DHCP to obtain IPv6 addresses. A DHCPv6 server must be present on the network.

Obtain IPv6 addresses automatically through Router Advertisement

Use router advertisement to obtain IPv6 addresses.

Static IPv6 addresses

a

Click Add to add a new IPv6 address.

b

Enter the IPv6 address and subnet prefix length, and click OK.

c

To change the VMkernel default gateway, click Edit.

The VMkernel Default Gateway address for IPv6 is obtained from the selected TCP/IP stack.

In the Advanced Settings section of IP Settings, you can remove IPv6 addresses. If router advertisement is enabled, removed addresses from this origin might reappear. Removal of DHCP addresses on the VMkernel adapter is not supported. These addresses are removed only when the DHCP option is turned off.

8

On the Validate changes page, verify that the changes made to the VMKernel adapter will not disrupt other operations.

9

Click OK.
