All DNS requests except SRV records are converted to HOSTENT structures.
The IAD will cache a maximum of 10 records, which will remain cached until
the shortest TTL in the record expires, or the least recently used record is
deleted for a subsequent DNS request. Note the TTL values are supplied by
the DNS server, not the IAD.
Press any key to return to the DNS Client menu when you have finished
reviewing the information.
Configure DHCP Client
1 Type “H” on the Router Configuration menu (Figure 4.59) to select
Configure DHCP Client. If more than one WAN port is installed or more
than one PVC or DLCI exists, the IAD displays the available interfaces
(sample shown in Figure 4.60):
2 Type the interface number to set. The IAD displays the port table for this
interface and prompts you for a port number.
3 Type the port to set and press Enter. The IAD displays the status of the
selected slot and port, and prompts you to change it.
4 Type “E” to enable DHCP Client on this port, or “D” to disable it. The
IAD saves the changes and displays the Router Configuration menu (Figure
4.59). Repeat these steps for each remaining port.
5 Continue with other configuration tasks, or press Escape to return to the
Main menu.

separate DHCP Server. To configure the IAD for DHCP Relay, type “L” on
the Router Configuration menu (Figure 4.59). The IAD displays the DHCP
Relay menu (Figure 4.63), which contains commands to configure DHCP
