DHCPD floods DHCPREQUEST via l4tbr0

Hi all,
For some reasons, when I’m connected to my Orin NX (Jetpack 5.1.2), my syslog is full of DHCPREQUEST via l4tbr0. I’m connected to my laptop (Ubuntu 22.04) on a USB-C port.
On Ubuntu I often get the notification:

Hi,
Would like to get more information about the setup. So you connect Orin NX to Ubuntu host through type-C to C cable. And Orin NX enters device mode but the prints are continually present in syslog. Is this correct? Would like to understand the error condition correctly.

Hi @DaneLL correct.
I plug it to my laptop throught type-C (host-side) to microUSB (Seeedstudio A603 carrier board) and I can log into my Orin NX via ssh nvidia@192.168.55.1.

This doesn’t happen if it’s not connected via USB. I tried to ssh via wlan0 and I had no dhcpd entries in the log.
This is what happen as soon as I plug it via USB:

Please change the dhcp lease time in the nv-l4t-usb-device-mode-config.sh and see if that changes the behavior.

I set it to 60 (before was 15) and this is the new log in the orin a bit after rebooting:

Is there any other DHCP client running and fighting for the IP?

Hi @WayneWWW
To be sure, I reinstalled a fresh Jetpack 5.1.2 on my Orin NX (I only applied the RT kernel patches on my L4T sources).

The only thing I did is to connect with nmtui my NETELY Intel Wireless ac 8265NGW to a local wifi. Obviously I’m connected to my NX via USB ssh (192.168.55.1).

This is the log I got:

Could you directly modify the IP from 192.168.55.100 to other setting and see if issue is still?

Also, remove all the other networks on the device and also the one that connected on USB host side.

I’m a bit confused here.
On my host Ubuntu 22.04, as soon as I connect the Nvidia Orin NX usb cable, I see two new interfaces: enxf6d1c851a384 and enxf6d1c851a386.

With the DHCP auto, one of the two gets 192.168.55.100.
I can manually set it to 192.168.55.42, netmask 24 and 192.168.55.1 gw. If I do it, the other network takes the id 100.

22: enxf6d1c851a384: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UNKNOWN group default qlen 1000

inet6 fe80::f15e:ebbf:6566:84e/64 scope link noprefixroute
valid_lft forever preferred_lft forever

If I now disable enxf6d1c851a386 on my host, I stop seeing the requests on the Orin. As soon as I re-enable it, the requests restart.

Also, remove all the other networks on the device and also the one that connected on USB host side.

At the moment I see one ‘Wired connection 1’ and one Bridge l4tbr0 connection on nmtui.
