Claim 14:
15. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
causing ports of a 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 a network in which the first network device and second network device are located, 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.
