Assigning Switch Information
EXAMPLE
This example shows how to configure a switch as a DHCP server to download a configuration file:
Switch# configure 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)# exit
Switch(config)# tftp-server flash:config-boot.text
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
Configuring DHCP Auto-Image Update (Configuration File and Image)
Follow this procedure to configure DHCP autoconfiguration to configure TFTP and DHCP settings on a
new switch to download a new image and a new configuration file.
BEFORE YOU BEGIN
You must create a text file (for example, autoinstall_dhcp) that will be uploaded to the switch. In the text
file, put the name of the image that you want to download. This image must be a tar and not a bin file.

Step 2
ip dhcp pool name Create a name for the DHCP server address pool and enter DHCP

Step 3
bootfile filename Specify the name of the file that is used as a boot image.
Step 4
network network-number mask
prefix-length
Specify the subnet network number and mask of the DHCP
address pool.
Note The prefix length specifies the number of bits that
comprise the 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 (/).
Step 5
default-router address Specify the IP address of the default router for a DHCP client.
Step 6
option 150 address Specify the IP address of the TFTP server.
Step 7
option 125 hex Specify the path to the text file that describes the path to the
image file.
Step 8
copy tftp flash filename.txt Upload the text file to the switch.
