6 Configuring DHCP, DNS, LDAP, and schema-free LDAP This chapter provides information on how to configure DHCP, DNS, LDAP extended schema, and schema-free LDAP. 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 3 MP host name you set through this method appears at the iLO 3 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 3 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 (0.0.0.0). 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: NOTE: The LC command sets the next boot LAN settings. It does not display the current settings. To display the current settings, you must use the LS command. When you change settings using the LC command, the settings do not take effect until the next boot of the iLO. • Set all default LAN settings. [hostname] CM:hpiLO-> LC -all DEFAULT -nc • Display current LAN settings. [hostname] CM:hpiLO-> LC -nc • Modify the MP DHCP status. [hostname] CM:hpiLO-> LC -dhcp disabled • Modify the MP IP address. [hostname] CM:hpiLO-> LC -ip 192.0.2.1 • Modify the MP host name. [hostname] CM:hpiLO-> LC -h hostname • Modify the MP subnet mask. [hostname] CM:hpiLO-> LC -s 255.255.255.0 32 Configuring DHCP, DNS, LDAP, and schema-free LDAP

6 Configuring DHCP, DNS, LDAP, and schema-free LDAP
This chapter provides information on how to configure DHCP, DNS, LDAP extended schema, and
schema-free LDAP.
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 3 MP host name you set through this method appears at the iLO 3 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
3 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 (0.0.0.0). 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:
NOTE:
The
LC
command sets the next boot LAN settings. It does not display the current settings.
To display the current settings, you must use the
LS
command. When you change settings using
the
LC
command, the settings do not take effect until the next boot of the iLO.
•
Set all default LAN settings.
[hostname] CM:hpiLO-> LC -all DEFAULT
–
nc
•
Display current LAN settings.
[hostname] CM:hpiLO-> LC -nc
•
Modify the MP DHCP status.
[hostname] CM:hpiLO-> LC -dhcp disabled
•
Modify the MP IP address.
[hostname] CM:hpiLO-> LC -ip 192.0.2.1
•
Modify the MP host name.
[hostname] CM:hpiLO-> LC -h hostname
•
Modify the MP subnet mask.
[hostname] CM:hpiLO-> LC -s 255.255.255.0
