Configuring the DHCP Client
8.5 TCP/IP Management Commands
Note that this command does not change the current run-time configuration of
the interface. For any changes to the TCPIP$CONFIGURATION database to
take effect, you must run $TCPIP$STARTUP or enter a TCP/IP command START
COMMUNICATION/INITIALIZE.
The format of the command is:
SET CONFIGURATION INTERFACE ifname/DHCP [/[NO]PRIMARY]
In this format, ifname is the name of the interface; for example, SE0.
The optional qualifier /PRIMARY indicates that the interface is to be the primary
DHCP client interface. (See Section 8.1.1 for a description of the DHCP client
primary interface.) TCP/IP Services issues an error if one of the other interfaces
has the primary designation.
/NOPRIMARY indicates that the interface is no longer to be marked as the
primary DHCP client interface. It is not an error if turning off this option leaves
no primary DHCP interfaces, because a primary DHCP interface is not required.
You do not need to issue this command because TCPIP$CONFIG executes the
command for you when you put an interface under DHCP control.
8.6 Using the SHOWDHC Utility
TCP/IP Services provides the SHOWDHC utility for displaying the contents of an
interface parameter file.
The SHOWDHC utility displays data stored in an ifname.DHC file.
The format of the SHOWDHC utility command is as follows:
SHOWDHC filename
In this format, filename is the name of an ifname.DHC file.
The format of the SHOWDHC output is a single line in the format of the
DHCPCAP. file. For more information on the format of the DHCPCAP. file,
refer to Section 7.2.2.2. Example 8–2 shows typical output from the SHOWDHC
utility.
