For hosts that are associated with a distributed switch, you can assign physical NICs to uplinks on the switch. You can configure physical NICs on the distributed switch for multiple hosts at a time.

About this task

For consistent networking configuration throughout all hosts, you can assign the same physical NIC on every host to the same uplink on the distributed switch. For example, you can assign vmnic1 from hosts ESXi A and ESXi B to Uplink 1.

Procedure

  1. In the vSphere Web Client, navigate to the distributed switch.
  2. From the Actions menu, select Add and Manage Hosts.
  3. In Select task, select Manage host networking and click Next.
  4. In Select hosts, click Attached hosts and select from the hosts that are associated with the distributed switch.
  5. Click Next.
  6. In Select network adapter tasks, select Manage physical adapters and click Next.
  7. In Manage physical network adapters, select a physical NIC from the On other switches/unclaimed list.

    If you select physical NICs that are already assigned to other switches, they are migrated to the current distributed switch.

  8. Click Assign uplink.
  9. Select an uplink or select Auto-assign.
