You have set the new link aggregation group (LAG) as standby in the teaming and failover order of distributed port groups. Having the LAG as standby lets you safely migrate the physical NICs from standalone uplinks to the LAG ports without losing network connectivity.
Verify that either all LAG ports or the corresponding LACP-enabled ports on the physical switch are in active LACP negotiating mode.
Verify that the physical NICs that you want to assign to the LAG ports have the same speed and are configured at full duplex.
- In the vSphere Web Client, navigate to the distributed switch where the LAG resides.
- From the Actions menu, select Add and Manage Hosts.
- Select Manage host networking.
- Select the host whose physical NICs you want to assign to the LAG ports and click Next.
- On the Select network adapter tasks page, select Manage physical adapters and click Next.
- On the Manage physical network adapters page, select a NIC and click Assign an uplink.
- Select a LAG port and click OK.
- Repeat 6 and 7 for all physical NICs that you want to assign to the LAG ports.
- Complete the wizard.
Configure Two Physical NICs to a LAG in the Add and Manage Hosts Wizard
For example, if you have a LAG with two ports, you configure a physical NIC to each LAG port in the Add and Manage Hosts wizard.
What to do next
Set the LAG as active and all standalone uplinks to unused in the teaming and failover order of distributed port groups.
