5 Configuring DHCP, DNS, LDAP, and LDAP Lite
This chapter provides information on how to configure DHCP, DNS, LDAP extended schema,
and LDAP Lite default schema.
This chapter addresses the following topics:
• “Configuring DHCP” (page 53)
• “Configuring DNS” (page 54)
• “Configuring LDAP Extended Schema” (page 55)
• “Configuring LDAP Lite Default Schema” (page 56)
Configuring DHCP
DHCP enables you to automatically assign reusable IP addresses to DHCP clients. This section
provides information on how to configure DHCP options such as the Domain Name System
(DNS).
The iLO 2 MP host name you set through this method displays at the iLO 2 MP command mode
prompt. Its primary purpose is to identify the iLO 2 MP LAN interface in a DNS database.
NOTE: The HP-UX system name displayed by the uname -a command is different than the
iLO 2 MP host name.
If the IP address, gateway IP address, and subnet mask are obtained through DHCP, you cannot
change them without first disabling DHCP. If you change the host name and the IP address was
obtained through DHCP and registered with dynamic DNS (DDNS), a “delete old name” request
for the old host name and an “add name request” for the new host name are sent to the DDNS
server.
If you change the DHCP status between enabled and disabled, the IP address, subnet mask, and
gateway IP address are set to default values (127.0.0.1:0xffffff00). Also, the DNS parameters are
voided. When you change the DHCP status from enabled to disabled, the DNS parameters for
using DHCP are set to disabled, and the Register with DDNS parameter is set to No. When
you change the DHCP status from disabled to enabled, the DNS parameters for using DHCP are
set to enabled, and the Register with DDNS parameter is set to Yes.
NOTE: DNS is the comprehensive RFC standard; DDNS provides only a part of the DNS
standard functionality.
Use the LC command to perform the following actions to configure DHCP:
• Set all default LAN settings.
MP:CM> LC -all DEFAULT –nc
• Display current LAN settings.
MP:CM> LC –nc
• Modify the MP DHCP status.
MP:CM> LC –dhcp disabled
• Modify the MP IP address.
MP:CM> LC -ip 192.0.2.1
• Modify the MP host name.
MP:CM> LC -h hostname
