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
enable Enables automatic IP address configuration for default VLAN 1.
disable Disables automatic IP address configuration for default VLAN 1.
Defaults
By default, this feature is disabled on the switch.
Platforms Supported
OmniSwitch 10K
Usage Guidelines
•
Use the ip helper boot-up enable command to specify BootP or DHCP for the request packet type.
•
If an IP router port already exists for VLAN 1, a request packet is not broadcast even if automatic IP
address configuration is enabled for the switch.
