System Administration Guide: IP Services

Specifying Network Interfaces for DHCP Monitoring

By default, both dhcpconfig and DHCP Manager's Configuration Wizard configure the DHCP server to monitor all the server system's network interfaces. If you add a new network interface to the server system, the DHCP server automatically monitors the new interface when you boot the system. You can then add any networks to be monitored through the network interface.

However, you can also specify which network interfaces should be monitored, and which interfaces should be ignored. You might want to ignore an interface if you do not want to offer DHCP service on that network.

If you specify that any interface should be ignored, and then install a new interface, the DHCP server ignores the new interface. You must add the new interface to the server's list of monitored interfaces. You can specify interfaces with DHCP Manager or the dhcpconfig utility.

This section includes procedures that enable you to specify which network interfaces DHCP should monitor or ignore. The DHCP Manager procedure uses the Interfaces tab of the DHCP Manager's Modify Service Options dialog box, which is shown in the following figure.
