ip helper boot-up
Enables or disables automatic IP address configuration for default VLAN 1 when an unconfigured switch
boots up. If enabled, the switch broadcasts a BootP or a DHCP request packet at boot time. When the
switch receives an IP address from a BootP/DHCP server, the address is assigned to default VLAN 1.
Note. Automatic IP address configuration only supports the assignment of a permanent IP address to the
switch. Make sure that the DHCP server is configured with such an address before using this feature.
ip helper boot-up {enable | disable}
Syntax Definitions

Defaults
By default, this feature is disabled on the switch.

Usage Guidelines
• Use the ip helper boot-up enable command to specify BootP or DHCP for the request packet type.

address configuration is enabled for the switch.
