SmartFabric services use the MAC addresses of the ESXi server NICs for onboarding. Before shutting down the existing hosts, note the MAC address of the server NICs. Two ways to determine the MAC addresses of the server NICs are described below.
One way is that you can use the OS10 switch CLI to get the MAC address of the interfaces on that server using the show lldp neighbors command. The NICs must support LLDP to use this method.
Alternatively, you can use the Direct Console User Interface (DCUI) on the server to get the details of the network adapters.
Browse to the DCUI of the specific server.
Select Configure Management Network.
Select Network Adapters.
Select the NIC, and then press D to view details including the full MAC address.
