Beginning in privileged EXEC mode, follow these steps to configure a switch to download a 
configuration file and new image from a DHCP server:

This example uses a Layer 3 SVI interface on VLAN 99 to enable DHCP-based autoconfiguration with 
a saved configuration:

Switch# configure terminal 

Switch(conf)# boot host dhcp

Switch(conf)# boot host retry timeout 300

Switch(conf)# banner config-save ^C Caution - Saving Configuration File to NVRAM May Cause 

Switch(config)# vlan 99

Switch(config-vlan)# interface vlan 99

Switch(config-if)# no shutdown

Switch(config-if)# end

Switch# show boot

BOOT path-list:

Config file:          flash:/config.text

Private Config file:  flash:/private-config.text

Enable Break:         no

Manual Boot:          no

HELPER path-list:

NVRAM/Config file

      buffer size:    32768

Timeout for Config

          Download:    300 seconds

Config Download

       via DHCP:       enabled (next boot: enabled)

Switch#

Enter global configuration mode.

Enable autoconfiguration with a saved configuration.

boot host retry timeout timeout-value

(Optional) Set the amount of time the system tries to 
download a configuration file.

If you do not set a timeout the system will 
indefinitely try to obtain an IP address from the 
DHCP server.

banner config-save ^C warning-message ^C

(Optional) Create warning messages to be displayed 
when you try to save the configuration file to NVRAM.

end 

Return to privileged EXEC mode.

Verify the configuration.
