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 43) • "Configuring DNS" (page 44) • "Configuring LDAP Extended Schema" (page 44) • "Configuring LDAP Lite Default Schema" (page 46) 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 MP host name you set through this method displays at the iLO MP command mode prompt. Its primary purpose is to identify the iLO MP LAN interface in a DNS database. NOTE: The HP-UX system name, displayed by the uname -a command, is different than the iLO 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 iLO MP 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 MP DHCP status: MP:CM> LC -dhcp disabled (or LC -d d ) • Modify MP IP address: MP:CM> LC -i 192.0.2.1 (or LC -ip 192.0.2.1) • Modify MP host name: MP:CM> LC -h hostname (or LC -host hostname) • Modify MP subnet mask: MP:CM> LC -s 192.0.2.1 (LC -subnet 192.0.2.1) Configuring DHCP 43

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 43)
•
“Configuring DNS” (page 44)
•
“Configuring LDAP Extended Schema” (page 44)
•
“Configuring LDAP Lite Default Schema” (page 46)
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 MP host name you set through this method displays at the iLO MP command mode
prompt. Its primary purpose is to identify the iLO MP LAN interface in a DNS database.
NOTE:
The HP-UX system name, displayed by the
uname -a
command, is different than the
iLO 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 iLO MP
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 MP DHCP status:
MP:CM> LC
–
dhcp disabled (or LC -d d )
•
Modify MP IP address:
MP:CM> LC -i 192.0.2.1 (or LC -ip 192.0.2.1)
•
Modify MP host name:
MP:CM> LC -h hostname (or LC -host hostname)
•
Modify MP subnet mask:
MP:CM> LC -s 192.0.2.1 (LC -subnet 192.0.2.1)
