DHCP
The initial switch configuration (for example, assigning the switch IP address and default gateway
information) can be performed through the switch setup program, manually, or through a Dynamic Host
Configuration Protocol (DHCP) server.
• Use the switch setup program if you want to be prompted for specific IP information.
For more information about the setup program, see the “Configuring the Switch with the CLI-Based
Setup Program” appendix in the Cisco 1E 2000U Switch Hardware Installation Guide.
• If you are an experienced user familiar with the switch configuration steps, use the CLI to manually
configure the switch. Otherwise, use the switch setup program.
• Use a DHCP server for centralized control and automatic assignment of IP information after the
server is configured.
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 the other is 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. The switch can act as both a DHCP client
and a DHCP server.
