Assigning Switch Information
This example shows how to configure a switch as a DHCP server so that it will download a configura-
tion 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 gigabitethernet0/1
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)
Beginning in privileged EXEC mode, follow these steps to configure DHCP autoconfiguration to
configure TFTP and DHCP settings on a new switch to download a new image and a new configuration
file.
Note Before following the steps in this table, 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 9 interface interface-id Specify the address of the client that will receive the configuration
file.
Step 10 no switchport Put the interface into Layer 3 mode.
Step 11 ip address address mask Specify the IP address and mask for the interface.
Step 12 end Return to privileged EXEC mode.
Step 13 copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 ip dhcp pool name Create a name for the DHCP server address pool and enter DHCP pool
configuration mode.
Step 3 bootfile filename Specify the name of the file that is used a s 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.
