DHCP Settings
As a Dynamic Host Control Protocol (DHCP) ser ver, your Motorola Netopia® Gateway can assign IP
addresses and provide configuration information to other devices on your network dynamically. A device
that acquires its IP address and other TCP/IP configuration settings from the Motorola Netopia® Gate-
way can use the information for a fixed period of time (called the DHCP lease).
Common Commands
set dhcp option { off | server | relay-agent }
Enables or disables DHCP ser vices in the Motorola Netopia® Gateway. You must enable DHCP ser vices
before you can enter other DHCP settings for the Motorola Netopia® Gateway.
If you turn off DHCP ser vices and save the new configuration, the Motorola Netopia® Gateway clears its
DHCP settings.
set dhcp start-address ip_address
If you selected server , specifies the first address in the DHCP address range. The Motorola Neto-
pia® Gateway can reser ve a sequence of up to 253 IP addresses within a subnet, beginning with the
specified address for dynamic assignment.
set dhcp end-address ip_address
If you selected server , specifies the last address in the DHCP address range.
set dhcp lease-time lease-time
If you selected server , specifies the default length for DHCP leases issued by the Motorola Netopia®
Gateway. Enter lease time in dd:hh:mm:ss (day/hour/minute/second) format.
set dhcp option-group name
Specifies a name for one of up to eight DHCP Option Groups. Each Option Group can have a name of
between 1 and 15 characters. The name is used in the DHCP filterset syntax to choose what group of
gen-options is to be ser ved to a par ticular DHCP Client. See
“DHCP Generic Options” on page 154 and
“DHCP Option Filtering” on page 157 .
Option Groups refer to gen-options; they do not contain them. Deleting a gen-option from an option
group does not delete the option. Adding a gen-option to an option-group does not preclude it from
being added to another option-group.
set dhcp default-option-group name
Sets the option group specified by name as the default.
set dhcp server-address ip_address
If you selected relay-agent , specifies the IP address of the relay agent ser ver.
