1. A method for automated device deployment in a hierarchical order in a network of devices, the method comprising:
booting up a first network device;
causing ports of the first network device to enter an initialization mode, wherein the ports are unable to transmit locally generated Dynamic Host Configuration Protocol (DHCP) packets in the initialization mode;
determining that a second network device has at least one of (i) been given a first Internet Protocol (IP) address or (ii) has been configured by a controller associated with the network, wherein the second network device is upstream from the first network device in the network;
causing a first port of the ports to enter a forwarding mode in which the first port is able to transmit DHCP packets to the second network device;
transmitting, from the first network device and using the first port, one or more first DHCP packets to prompt a server to offer the first network device a second IP address; and
receiving, at the first network device, one or more second DHCP packets that include the second IP address given to the first network device.
