Devices Information Assignment
You can assign IP information through the device setup program, through a DHCP server, or manually.
Use the device setup program if you want to be prompted for specific IP information. With this program, you
can also configure a hostname and an enable secret password.
It gives you the option of assigning a Telnet password (to provide security during remote management) and
configuring your switch as a command or member switch of a cluster or as a standalone switch.
Use a DHCP server for centralized control and automatic assignment of IP information after the server is
configured.
If you are using DHCP, do not respond to any of the questions in the setup program until the device receives
the dynamically assigned IP address and reads the configuration file.
Note
If you are an experienced user familiar with the device configuration steps, manually configure the device.
Otherwise, use the setup program described in section
Device Boot Process, on page 47

DHCP-Based Autoconfiguration Overview
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 an
operation 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 device can act as both a DHCP client and a DHCP server.
