Dynamic Host Configuration Protocol

Dynamic host configuration protocol (DHCP) is an application layer protocol that dynamically assigns IP addresses and other
configuration parameters to network end-stations (hosts) based on the configuration policies the network administrators
determine.
The Dell Networking OS supports the basic DHCP commands as described in the following sections:
