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 -acommand 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
