When entering two commands in the same line, you need to separate them with the semicolon to ensure that the two commands can be sent simultaneously After you run the two commands, the device will be disconnected from the network. You need to re-connect the device to the network.
                               Step 2     Run the setup command and configure the NIC according to the prompts (in order to add the MAC address in the configuration file ifcfg-eth0.cfg).
