Assign DHCP IP Addresses Using an Ethernet Managment Connection

Follow these insturctions when using DHCP to aassign IP addresses:

Prerequisite

What to Do

  1. Verify that your DHCP server is configured to accept new media access control (MAC) addresses.

    Consult the documentation supplied with your DHCP server software.

  2. Verify that an Ethernet cable is plugged into either the :the NET MGT port on the

    • Ethernet port (NET MGT) port on the active CMM.

    • Ethernet port (NET MGT) port on a rackmount standalone server, if applicable.

    Note

    For the Sun Blade 8000 Series Modular Systems, you must connect the ethernet cable to the NET MGT port on the active CMM to assign DHCP addresses to all Server Module SPs in the chassis.

    Note

    Provided that ILOM was not configured previously with a static IP address, ILOM automatically broadcasts a DHCPDISCOVER packet with the ID of its SP network interface(s) MAC address(es). If ILOM was previously configured with a static IP address, you must disable the static IP address setting on the Network Settings tab. For more information about editing IP address settings, see Edit IP Address Assignment Using an Ethernet Management Connection.

  3. The DHCP server on your network returns the DHCPOFFER packet containing the IP address and other information. The CMM (or standalone server SP) then manages its "lease" of IP addresses assigned by the DHCP server.

  4. Use one of the following methods to obtain DHCP IP addresses assigned to the SP network interfaces

    • ILOM-CMM using serial connection

      Using a serial console attached to the rear panel of the CMM, log in to ILOM as the Administrator. For example, at the login prompt, you could type the preconfigured administrator username root and its default password changeme, then press Enter.

      • To set the working directory for the active CMM, type:

        cd /CMM/network/CMM0

      • To view the active CMM IP address, type: show

      • To drill-down and view each blade's IP address, type:

        show /CH/BL0/SP/network

      Note

      CMM0 represents the CMM installed in slot CMM-0. BL0 represents the blade installed in slot BL-0. To specify the target CMM or blade, you must specify the slot number of where the module is installed. Blade slots range from 0 to 9. CMM slots range from 0 to 1.

    • ILOM-Server SP using serial connection

      Using a serial console attached to the front panel of a Server Module, log in to ILOM as the Administrator . For example, at the login prompt, you could type the preconfigured administrator username, root and its default password changeme, then press Enter.

      • To view the server SP IP address, type: show /SP/network

    • DHCP server logs
