Chapter 3 Assigning the Switch IP Address and Default Gateway
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 pool
1
Switch(dhcp-config)# network 10.1
0.10.0 255.255.255.0
Switch(dhcp-config)# bootfile con
fig-boot.text
Switch(dhcp-config)# default-rout
er 10.10.10.1
Switch(dhcp-config)# option 150 1
0.10.10.1
Switch(dhcp-config)# exit
Switch(config)# tftp-server flash
:config-boot.text
Switch(config)# interface gigabit
ethernet1/0/4
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)
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 (for
example, 3750x-ipservices-mz.122-53.3.SE2.tar). This image must be a tar and not a bin file.
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
exit Return to global configuration mode.
Step 8
tftp-server flash:filename.text Specify the configuration file on the TFTP server.
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.
