Unexpected behavior you saw
With a fresh build, I am unable to configure the IP address of eth1 (NCSI)

Expected behavior
It shall be able to configure the IP address of eth1

To Reproduce
Steps to reproduce the behavior:

  1. Build and flash a fresh build of Intel-BMC/openbmc on CRB
  2. Boot into OS
  3. Run inband ipmi command to configure the IP: 
    ipmitool lan set 1 ipsrc static
ipmitool lan set 1 ipaddr <ip>
ipmitool lan set 1 netmask 255.255.255.0
ipmitool lan set 1 defgw ipaddr <gw-ip>
  4. Wait for a few seconds, check the IP address, it's empty. 
    # ipmitool lan print 1
 Set in Progress         : Set Complete

 IP Address Source       : Static Address
 IP Address              : 0.0.0.0
 Subnet Mask             : 255.255.255.255
 MAC Address             : <mac>
 Default Gateway IP      : 0.0.0.0
 Default Gateway MAC     : 00:00:00:00:00:00
 802.1q VLAN ID          : Disabled
 RMCP+ Cipher Suites     : 3,17
 Cipher Suite Priv Max   : Not Available
 Bad Password Threshold  : Not Available
  5. Connect BMC debug UART, configure the IP with dbus:
root@intel-obmc:~# busctl call xyz.openbmc_project.Network /xyz/openbmc_project/network/eth1 xyz.openbmc_project.Network.IP.Create IP ssys "xyz.openbmc_project.Network.IP.Protocol.IPv4" "<ip>" 24 "<gw-ip>"
o "/xyz/openbmc_project/network/eth1/ipv4/88e39147"

The DBus call itself succeds, but the IP is not correctly configured, and after a few seconds, the D-Bus object /xyz/openbmc_project/network/eth1/ipv4/88e39147 disappears.

Please also provide the CRB BIOS version.

I double checked in my side. Don't find such issue. System is working well.

NOTE: 1. Please remove asd, your met build issue.
https://github.com/Intel-BMC/openbmc/blob/intel/meta-openbmc-mods/meta-common/classes/obmc-phosphor-image-common.bbclass#L14
2. Please make sure using the correct config based your CRB platform, take wht for example.
export TEMPLATECONF=meta-openbmc-mods/meta-wht/conf/
Please remove the whole build folder if you changed the config.
3. Please make the drive working well.
root@intel-obmc:~# cat /sys/class/net/eth1/address

OK, will try to clean the build dir and try a clean build.

From your log, both eth0 and eth1 are connected. Please be noted that this issue occurs when only eth1 (NCSI) is connected, while eth0 is disconnected.

kuiyingw commented

Still working well, even disconnect the eth0.
BTW: Please make sure your system could get MAC address correctly.

mine260309 commented

What I observe is that the issue occurs on both eth0 and eth1.
Below is how I reproduce the issue:

  1. Do a factory reset, so that BMC's settings are default
  2. Connect to BMC's debug UART, check the default eth configs: 
     # cat /etc/systemd/network/00-bmc-eth1.network
 [Match]
 Name=eth1
 [Link]
 MACAddress=<xxx>
 Unmanaged=yes
 [Network]
 LinkLocalAddressing=yes
 IPv6AcceptRA=false
 DHCP=false
 [DHCP]
 ClientIdentifier=mac
 UseDNS=true
 UseNTP=true
 UseHostname=true
 SendHostname=true
    Be noted Unmanaged=yes is the root cause.
  3. Assign an IP address, e.g. 
    # busctl call xyz.openbmc_project.Network /xyz/openbmc_project/network/eth1 xyz.openbmc_project.Network.IP.Create IP ssys "xyz.openbmc_project.Network.IP.Protocol.IPv4" 
"192.168.1.101" 24 "192.168.1.1"
    The expected behavior is that the IP will be added to eth1. But no IP is added.
    Checking the config: 
     # cat /etc/systemd/network/00-bmc-eth1.network
 [Match]
 Name=eth1
 [Link]
 MACAddress=<xxx>
 Unmanaged=yes
 [Network]
 LinkLocalAddressing=yes
 IPv6AcceptRA=false
 DHCP=false
 [Address]
 Address=192.168.1.101/24
 [DHCP]
 ClientIdentifier=mac
 UseDNS=true
 UseNTP=true
 UseHostname=true
 SendHostname=true
    We can see that the IP is correctly written into the config, but due to Unmanaged=yes, systemd-networkd will not use this config file.
kuiyingw commented

Seems there is an issue on setting the static ip addr.
You could use DHCP get the ip address.
It should not block you.
