How to Configure BMC MAC/IP address

There are several approaches to access BMC to change MAC/IP Address.

This procedures will walk you through how to do that.

Note: Default network configuration on BMC is static mode with 192.168.0.100 (IP address)/00:00:00:00:00(MAC address)


Using IPMI Network to change MAC/IP Address

Before you begin,

  • Prepare the Ethernet cable and connect to your host machine and AADK system like this:

  • Download & Install IPMI Management Utility on your host machine

    • Ubuntu: Type the below commands to install

      sudo apt update
      sudo apt install ipmitool
    • Windows 10: Click here

  • Confirm the connection is alive between your host machine and AADK system

    In your host Machine with Linux Environment:

    • Type the below command to configure the static IP address

      sudo ifconfig eth0 192.168.0.22 netmask 255.255.255.0

In your host Machine with Windows Environment:

  • Configure the static IP Address on the network device and save it:

  • Type the Ping command to see if the connection is alive between your host machine and the AADK system

    sushi@Sushi:~$ ping 192.168.0.100
    PING 192.168.0.100 (192.168.0.100) 56(84) bytes of data.
    64 bytes from 192.168.0.100: icmp_seq=1 ttl=64 time=0.569 ms
    64 bytes from 192.168.0.100: icmp_seq=2 ttl=64 time=0.572 ms
    64 bytes from 192.168.0.100: icmp_seq=3 ttl=64 time=0.560 ms


Getting Started

  • open cmd.exe (Windows Environment ) or terminal ( Linux Environment) on your host machine and execute the command to see the MMC FW is alive:

    Note: the Default network configuration is static mode with 192.168.0.100

    ipmitool -I lanplus -H 192.168.0.100 -U admin -P admin -b 0 -t 0x82 mc info


  • Type the below command to change MAC address on your host machine

    ipmitool -I lanplus -H 192.168.0.100 -U admin -P admin raw 0x0c 0x01 0x01 0xc2 0x00
    ipmitool -I lanplus -H 192.168.0.100 -U admin -P admin lan set 1 macaddr 00:11:22:33:44:55


  • Type the below command to configure DHCP Mode. (it would be for a while to configure it)

    ipmitool -I lanplus -H 192.168.0.100 -U admin -P admin lan set 1 ipsrc dhcp

​ it would be reacquired dynamical IP address and type the below command to see the network information.


​


  • Type the command to enable Static Mode and IP address will be automatically configured to the default 192.168.0.100

    ipmitool -I lanplus -H 192.168.0.100 -U admin -P admin lan set 1 ipsrc static



Using BMC Serial Console port

Before you begin,

  • There is 3 Pin header (BMC_DBG) on the carrier board that supports the serial console for BMC (with IPMI functions).

  • Prepare USB to TTL Serial Adapter 3.3V Debug Cable TX RX Signal 3 Pin like this:

image-20210830171550029

  • Plug the USBtoRS232 adapter cable to your host machine and connect 3 pins with the corresponding the pins.

    In your host Machine with Linux Environment:

    • Type this command to list the USB devices: lsusb

      sushi@Sushi:~$ lsusb
      Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
      Bus 001 Device 011: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC

    • once detected, the devices will be under the /dev/ path to see if the interface is visible with this command: ls /dev/ttyUSB0

    • If you are installing a Minicom serial device then follow the below procedure:

      sudo apt-get install minicom

      sudo minicom -s

      • Go to [Serial Port Setup] in the Configure of minicom application
      • Press A and then edit to /dev/ttyUSB0
      • Press E and then edit to 115200 8N1
      • Go to [Exit]

    • Then power on target system and you will get the booting messages from Serial Console

In your host Machine with Windows Environment:

  • The common terminal software is putty.

  • Putty is for free to download.

  • After executing it, please configure the following parameters

  • Select Connection type to Serial.

  • Modify Serial line to the COM port which is found in the device manager.

  • Set Speed to 115200.

  • Click Open button to enter serial console

  • After successful set up, you can see the logs from serial console and please use the credentials to login
    • Username: sysadmin
    • password: superuser


Getting Started

  • Configure MAC address on bootloader

    • Reboot or power on your system

    • Press any key when you see the following prompt:

      U-Boot 2013.07 (Jul 28 2021 - 14:09:52)

    • It will boot into u-boot

      U-Boot 2013.07 (Jul 28 2021 - 14:09:52)

      I2C:   ready
      DRAM:  448 MiB
      Flash: Found SPI Chip Micron/Numonyx N25Q512A(0x20ba) 2x I/O READ, NORMAL WRITE
      Found SPI Chip Micron/Numonyx N25Q512A(0x20ba) 2x I/O READ, NORMAL WRITE
      128 MiB
      MMC:
      Net:   ast_eth0
      DRAM ECC disabled
      Hit any key to stop autoboot:  0
      AST2500EVB>

    • Type the command to enter MAC address and then reboot the system

      Note: Please enter any value for MAC address because the default is 00:00:00:00:00:00

      setenv ethaddr 00:22:33:44:55:66
      saveenv

  • Check if MAC address is changed

    • Get into the BMC Linux

    • If the change becomes valid, you can see the prompt login message
      Note: ADL + your MAC address

      ADL002233445566 login:

  • Configure the static IP address

    • Type the command to enter IP address you want

      ifconfig eth0 192.168.0.100 netmask 255.255.255.0 up

      Once done with the above steps, BMC will be equipped with Ethernet function.
