You create VMkernel adapters to isolate the incoming replication traffic on target ESXi hosts.
One VMkernel adapter must handle one traffic type.
Perform this procedure for every ESXi host that is used as replication target, and for which you want to isolate the replication traffic.
Verify that the ESXi host is version 6.0 or later.
For distributed network switches, verify that you have a port group that you can dedicate to the new VMkernel adapter.
- In the vSphere Web Client, navigate to the ESXi host.
- Under Configure, select Networking, and select VMkernel adapters.
- Click the Add host networking icon .
The Add Networking wizard opens.
- On the Select connection type page, select VMkernel Network Adapter and click Next.
- On the Select target device page, select a port group or a standard switch and click Next.
- On the Port properties page, under VMkernel port settings, configure the IP settings and TCP/IP stack to comply with your environment.
vSphere Replication requires that all components in your environment, such as vCenter Server, ESXi hosts, and the vSphere Replication appliance use the same IP version, IPv4 or IPv6.
- Under Available services, select vSphere Replication NFC traffic and click Next.
- Apply the IP settings, click Next, and Finish to complete the wizard.
The VMkernel adapter that you tagged for NFC traffic appears in the list of adapters. The vSphere Replication Server routes the replication data to the adapter, and the ESXi host saves the data to a datastore.
