DHCP reduces the amount of work required toadminister a large network.Basic DHCP Server Setup TasksWhen DHCP is enabled, it dynamically assigns an IP address to each deviceassigned to the DHCP server on the IAD. You must identify the EthernetInterface to correctly implement DHCP Server on your IAD.You must complete at least these tasks to configure the DHCP server:• Enable DHCP (default is disabled) (page 4-129)• Configure the DHCP server parameters (page 4-130)• Configure the DHCP address range pool (page 4-130)DHCP Server Configuration MenuThe DHCP Server commands are all displayed on the DHCP ServerConfiguration menu, which is displayed by typing “D” on the Main menu.Remember always to reset the IAD when you have finished making DHCPServer configuration changes.
