The service console and the VMkernel use virtual Ethernet adapters to connect to a vSwitch and to reach networks that the vSwitch services.

Common service console configuration modifications include changing NICs and changing the settings for a NIC that is in use.

If there is only one service console connection, changing the service console configuration is not allowed. For a new connection, change the network settings to use an additional NIC. After you verify that the new connection is functioning properly, remove the old connection. You are switching over to the new NIC.

You can create a maximum of 16 service console ports in ESX.
