This example shows how to configure a switch as a DHCP server so it downloads a configuration file:
Switch# config terminal
Switch(config)# ip dhcp pool pool1
Switch(dhcp-config)# network 10.10.10.0 255.255.255.0
Switch(dhcp-config)# bootfile config-boot.text
Switch(dhcp-config)# default-router 10.10.10.1
Switch(dhcp-config)# option 150 10.10.10.1
Switch(dhcp-config)# option 125 hex
0000.0009.0a05.08661.7574.6f69.6e73.7461.6c6c.5f64.686370
Switch(dhcp-config)# exit
Switch(config)# tftp-server flash:config-boot.text
Switch(config)# tftp-server flash:image_name
Switch(config)# tftp-server flash:boot-config.text
Switch(config)# tftp-server flash: autoinstall_dhcp
Switch(config)# interface gigabitEthernet1/0/4
Switch(config-if)# no switchport
Switch(config-if)# ip address 10.10.10.1 255.255.255.0
Switch(config-if)# end

Purpose
Enter global configuration mode.
Create a name for the DHCP server address pool and enter DHCP pool
configuration mode.
Specify the name of the file that is used as a boot image.
Specify the subnet network number and mask of the DHCP address pool.
The prefix length specifies the number of bits that comprise the
Note
address prefix. The prefix is an alternative way of specifying the
network mask of the client. The prefix length must be preceded
by a forward slash (/).
Specify the IP address of the default router for a DHCP client.
Specify the IP address of the TFTP server.
Specify the path to the text file that describes the path to the image file.
Upload the text file to the switch.
Upload the tar file for the new image to the switch.
Return to global configuration mode.
Specify the Cisco IOS configuration file on the TFTP server.
Specify the image name on the TFTP server.
Specify the text file that contains the name of the image file to download
Specify the address of the client that will receive the configuration file.
Put the interface into Layer 3 mode.
Specify the IP address and mask for the interface.
Return to privileged EXEC mode.
(Optional) Save your entries in the configuration file.
