Configuring CIMC Access

This chapter includes the following sections:

E-Series Server Interfaces Overview

The following figure shows the interfaces in a double-wide E-Series Server.

Figure 1. Interfaces in a Double-Wide E-Series Server

 

Interface

Interface Location

Description

1

Router’s PCIe slot/0 Interface

Internal Interface

Also called Console interface. This interface connects the router’s PCIe interface to the E-Series Server. The PCIe interface provides an internal Layer 3 GE link between the router and the E-Series Server. It can be used both for CIMC configuration or for host operating system configuration.

2

Router’s MGF slot/1 VLAN Interface

Internal Interface

Used to access CIMC over a high-speed backplane switch. The MGF VLAN interface provides an internal Layer 2 GE link between the router and the E-Series Server. This interface can be used both for CIMC configuration or for host operating system configuration.

3

Management (Dedicated) Interface

External Interface

Used for CIMC configuration and management.

4

GE3 Interface

External Interface

Used as a primary interface or as a backup interface. This interface can be used both for CIMC configuration or for host operating system configuration.

Note   

The single-wide E-Series Server has one external interface, which is GE2.

5

GE2 Interface

External Interface

Used as a primary interface or as a backup interface. This interface can be used both for CIMC configuration or for host operating system configuration.

Note   

The single-wide E-Series Server has one external interface, which is GE2.

CIMC Access Configuration Options

Depending on whether you are a remote user or a local user, do one of the following to configure CIMC access.

  • If you are a remote user, use either the external Management (dedicated) interface or one of the following shared LOM interfaces to configure CIMC access:
    • Router's internal MGF slot/1 VLAN interface
    • E-Series Server’s external GE2 or GE3 interface
    • Router’s internal PCIe slot/0 Console interface
  • If you are a local user, use the Cisco IOS CLI or the CIMC Configuration Utility to configure CIMC access.

Configuring CIMC Access Using the E-Series Server's External Management (Dedicated) Interface

See the following figure and the procedure that follows to configure CIMC access using the E-Series Server's external Management (dedicated) interface.

          Note   

          The unnumbered interface must be unique. It cannot be another unnumbered interface.

          When you use the ip unnumbered command, you must use the ip route command to create a static route.

          Caution   

          The ip unnumbered and ipv6 unnumbered commands creates a point-to-point interface between devices. Broadcasting is not supported.

          Configuring CIMC Access Using the CIMC Configuration Utility

          If you are a local user, you can either use the Cisco IOS CLI or the CIMC Configuration Utility to configure CIMC access. To configure CIMC access using the Cisco IOS CLI, see Configuring CIMC Access Using the Cisco IOS CLI.


          Note

          When you use the CIMC Configuration Utility to configure CIMC access, the configuration is not reflected as Cisco IOS configuration. In other words, if you execute the show run command from Cisco IOS, the changes that you made using the CIMC Configuration Utility are not reflected.

          Procedure
            Step 1   Power on the router.
            Step 2   Connect a keyboard and monitor to the front panel for the E-Series Server.
            Step 3   Press the Power button to boot the E-Series Server. During bootup, watch for the prompt to press F8.
            Step 4   When you see the prompt, press F8.

            The CIMC Configuration Utility appears.

            Figure 6. CIMC Configuration Utility



            Step 5   Use the CIMC configuration Utility to set the NIC mode and NIC redundancy, and to choose whether to enable DHCP or set static network settings.
            1. From the NIC mode area, choose a port to access CIMC. Options are:
              • Dedicated—The 10/100 IMC port is used to access CIMC.
              • Shared LOM (default)—The four 1Gb Ethernet ports are used to access the CIMC. This is the factory default setting.
            2. From the NIC redundancy area, choose the NIC redundancy. Options are:
              • None—The Ethernet ports operate independently and do not fail over if there is a problem.
              • Active-standby—If an active Ethernet port fails, the traffic falls over to a standby port. This is the factory default setting.
            3. From the IPV4 (Basic) area, do one of the following:
              • DHCP Enabled—Select this option to enable DHCP for dynamic network settings. Before you enable DHCP, your DHCP server must be preconfigured with the range of MAC addresses for this server. The MAC address is printed on a label on the rear of the server. This server has a range of six MAC addresses assigned to CIMC. The MAC address printed on the label is the beginning of the range of six contiguous MAC addresses.
              • CIMC IP—IP address of CIMC. Subnet Mask—Enter the subnet mask to append to the CIMC IP address; must be in the same subnet as the host router. Gateway—IP address of the default gateway router.
            4. (Optional) From the VLAN (Advanced) area, configure VLAN settings.
            5. Press F5 to refresh the page and have the new settings appear.

              The page refresh takes approximately 45 seconds.

            6. Press F10 to save your settings and reboot the server.

              If you chose to enable DHCP, the dynamically assigned IP and MAC addresses are displayed on the console screen during bootup.

            Step 6   Using the ports that you selected for the NIC Mode settings in Step 5, substep a, connect Ethernet cables from your LAN to the E-Series Server.
            Step 7   In your web browser, enter the IP address that you configured to access CIMC. The CIMC IP address is based upon the settings that you configured in Step 5, substep c (either a static IP address or the IP address assigned by your DHCP server).

            The default user name to log into CIMC is admin and the default password is password.

            Step 8   Use the CIMC GUI or CIMC CLI to manage and monitor the server.

            See the GUI Configuration Guide for Cisco UCS E-Series Servers or the CLI Configuration Guide for Cisco UCS E-Series Servers.

            Defining Network Static Settings Using a Script File

            Use this procedure to define static network settings for multiple servers by automating the configuration process with a script file.
            Procedure
              Step 1   Use a text editor to create a file named network.cfg.
              Step 2   Create the contents of network.cfg in the following format by using only the tags that you want to set: 
              dhcp-enabled:
v4-addr:
v4-netmask:
v4-gateway:
vlan-enabled:
vlan-id:
vlan-priority:
password: 
mode:
redundancy:
              For example, to disable DHCP, set the IP address, subnet mask, gateway, and user password, use the following sample values:
              dhcp-enabled: 0
v4-addr: 10.193.70.102
v4-netmask: 255.255.255.0
v4-gateway: 10.193.70.1
password: nonpasswd
mode:
redundancy:
              Step 3   Use a text editor to create a file named startup.nsh with the following contents: 
              fs0:
cimcconfig
              Step 4   Copy your network.cfg file and your startup.nsh file to a USB thumb drive.
              Step 5   Insert the USB thumb drive into a USB port on the server.
              Step 6   Press and release the Power button to boot the server.
              Step 7   Observe the booting process and press F6 when prompted to enter the BIOS Boot Manager.
              Step 8   Select EFI as the boot device and then press Enter.

              The server power cycles and launches the configuration utility, which runs the startup.nsh file. Any errors are displayed on the screen and on an errors.txt file.

              Step 9   Remove the USB thumb drive, alter the network.cfg file with your next IP address, and then insert the USB thumb drive into the next server that you want to configure.
              Step 10   After the server has been assigned an IP address, you can use that address to access the service processor's GUI or CLI management system.
