		these clients in the general grouping of networks that make up the domain.
Import All		When selected, enables remote DHCP servers to import specific DHCP
		options (such as the DNS server) from a centralized server. Use this option
		to enable configuration information to be updated automatically.
		When deselected, all DHCP options are local to this specific server.
Secured ARP		When selected, enables the DHCP Authorized ARP feature, which limits the
		leasing of IP addresses to authorized mobile users. This feature helps prevent
		IP spoofing by unauthorized users. See Understanding Secured ARP,
		page 15-120.
		When deselected, the DHCP Authorized ARP feature is disabled.
		Note This feature also disables dynamic ARP learning on an interface.
Lease Never Expires		When selected, the DHCP server permanently assigns IP addresses to its
		clients.
		When deselected, addresses are leased for a predefined amount of time, as
		defined in the Time Length field.
Time Length		Applies only when the Lease Never Expires check box is deselected.
(DD:HH:MM)		The duration of the lease provided to each IP address assigned from this IP
		pool (using the format DD:HH:MM). After the lease expires, the assigned IP
		address is no longer valid and is returned to the pool.

Addresses)		phones. These configuration files define parameters required by IP phones to
		connect to Cisco CallManager.

		Select to display an Object Selectors, page F-593.
		If the network you want is not listed, click the Create button in the selector
		to display the Network/Host Dialog Box, page F-477. From here, you can
		define a network/host object.
