Dynamic Host Configuration Protocol

G8264 Application Guide for ENOS 8.4
Dynamic Host Configuration Protocol (DHCP) is a transport protocol that
provides a framework for automatically assigning IP addresses and configuration
information to other IP hosts or clients in a large TCP/IP network. Without DHCP,
the IP address must be entered manually for each network device. DHCP allows a
network administrator to distribute IP addresses from a central point and
automatically send a new IP address when a device is connected to a different
place in the network.
The switch accepts gateway configuration parameters if they have not been
configured manually. The switch ignores DHCP gateway parameters if the
gateway is configured.
DHCP is an extension of another network IP management protocol, Bootstrap
Protocol (BOOTP), with an additional capability of being able to allocate reusable
network addresses and configuration parameters for client operation.
Built on the client/server model, DHCP allows hosts or clients on an IP network to
obtain their configurations from a DHCP server, thereby reducing network
administration. The most significant configuration the client receives from the
server is its required IP address; (other optional parameters include the "generic"
file name to be booted, the address of the default gateway, and so forth).
To enable DHCP on a switch interface, use the following command:
RS G8264(config)# system dhcp
