No IPv6 address for tmfifo_net0 interface on host side

Infrastructure & Networking BlueField
1

Hello, I am trying to configure a host system with one BlueField-3 card, and I have tried the commands here (Deploying BlueField Software Using BFB from Host - NVIDIA Docs) for the purpose of ssh’ing into the DPU using an IPv6 address.

However, after trying the command:

systemctl restart rshim

The IPv6 address still didn’t occur on the tmfifo_net0 interface of the host:

zhiyihu@alveo-u50d-01:/tmp/build/file_compression$ ip addr
10: tmfifo_net0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000
    link/ether 00:1a:ca:ff:ff:02 brd ff:ff:ff:ff:ff:ff
    inet 192.168.100.1/30 scope global tmfifo_net0
       valid_lft forever preferred_lft forever

Could you help with it because I do not have sudo previlige on the system and the configuration for the virtual interface got restored daily. :

ip addr add dev tmfifo_net0 192.168.100.1/30

Or if you could provide another way for ssh’ing into the BlueField card, here is the current configuration on the BlueField card:

Hi huzhiyi1037,

Can you manually set the IPv6 address and ssh into the DPU to check if IPv6 is disabled on the host? I think you can log in to the DPU using an IPv4 address, but it will be restored, right? Can authorized person permanently configure IPv4 using a configuration file? Additionally, is it ok for you to use minicom to log into DPU? If none of the above works, you might try upgrading drivers and firmware.

Problem solved. Thanks a lot!
