Configuring the Client
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
