Configuring CIMC Access Using the EHWIC E-Series NCE's External GE2 Interface

Important

If you are using the external GE2 interface on an EHWIC E-Series NCE or the NIM E-Series NCE to configure CIMC access, to configure CIMC access, you might lose connectivity with CIMC during server reboot. This is expected behavior. If you must maintain connectivity with CIMC during a reboot, we recommend that you use one of the other network interfaces to configure CIMC access. See CIMC Access Configuration Options—EHWIC E-Series NCE.

If you want to use the external GE2 interface to configure CIMC access, we recommend that you use the spanning-tree portfast command. For details, see the CSCup50049 caveat in the Release Notes for Cisco UCS E-Series Servers and the Cisco UCS E-Series Network Compute Engine

See the following figure and the procedure that follows to configure CIMC access using the EHWIC E-Series NCE's external GE2 interface.

Configuring CIMC Access Using the CIMC Configuration Utility


Note

This procedure is applicable to E-Series Servers and the SM E-Series NCE. This procedure is not applicable to the EHWIC E-Series NCE and the NIM E-Series NCE.

If you are a local user, you can use either the Cisco IOS CLI or the CIMC Configuration Utility to configure CIMC access.


Note

When you use the CIMC Configuration Utility to configure CIMC access, the configuration is not reflected as a Cisco IOS configuration. In other words, if you execute the show running-config command from the Cisco IOS CLI, 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 of 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 22. 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 username to log in to 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 and the Cisco UCS E-Series Network Compute Engine or the CLI Configuration Guide for Cisco UCS E-Series Servers and the Cisco UCS E-Series Network Compute Engine.

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.

What to Do Next

Do one of the following as appropriate:

  • If you purchased an E-Series Server or NCE Option 1 (E-Series Server or NCE without a preinstalled operating system or hypervisor), log in to the CIMC GUI or the CIMC CLI to access CIMC. See Accessing the Management Firmware.

  • If you purchased an E-Series Server or NCE Option 2 (E-Series Server or NCE with a preinstalled Microsoft Windows Server) or Option 3 (E-Series Server or NCE with a preinstalled VMware vSphere Hypervisor), configure an internal connection between the router and the E-Series Server or NCE. Do one of the following:

    • If you do not want the traffic to your application or operating system to flow through the router, use the server’s host operating system to configure the E-Series Server’s or NCE's external interface.

    • If you want the traffic to your application or operating system to flow through the router, use the Cisco IOS CLI to configure an internal connection between the router and the E-Series Server or NCE. See Configuring a Connection Between the Router and the E-Series Server or NCE.
