Understanding DHCP-Based Autoconfiguration
The DHCP provides configuration information to Internet hosts and internetworking devices. This
protocol consists of two components: one for delivering configuration parameters from a DHCP server
to a device and a mechanism for allocating network addresses to devices. DHCP is built on a
client-server model, in which designated DHCP servers allocate network addresses and deliver
configuration parameters to dynamically configured devices.
During DHCP-based autoconfiguration, your switch (DHCP client) is automatically configured at
startup with IP address information and a configuration file.
With DHCP-based autoconfiguration, no DHCP client-side configuration is needed on your switch.
However, you need to configure the DHCP server for various lease options associated with IP addresses.
If you are using DHCP to relay the configuration file location on the network, you might also need to
configure a TFTP server and a Domain Name System (DNS) server.
The DHCP server can be on the same LAN or on a different LAN than the switch. If the DHCP server
is running on a different LAN, you should configure a DHCP relay. A relay device forwards broadcast
traffic between two directly connected LANs. A router does not forward broadcast packets, but it
forwards packets based on the destination IP address in the received packet.
DHCP-based autoconfiguration replaces the BOOTP client functionality on your switch.
