ipv4 – Incomplete MAC deal with utilizing static ip deal with


In my firm I’ve a setup the place i wish to have the choices to attach with a raspi over dhcp when utilizing LAN inside and a static fallback ip when connecting the raspi to my PCI ethernet port for testing in a thermal chamber. Due to this fact I configured two system connections on the raspi with Community Supervisor. DHCP with the upper precedence works simply positive that means i can change the Community Supervisor config however I am unable to join with the raspi over the static ip.

Wanting on the arp desk offers the next:

$arp -a
_gateway (192.168.1.1) at < incomplete > on enp4s0
? (192.168.1.71) at < incomplete > on enp4s0

On the raspi the Community Supervisor has these two config recordsdata:

[connection]
id=01DHCP
uuid=90088f39-750d-42df-b883-e55a1ec9feea
sort=ethernet
autoconnect-priority=1
autoconnect-retries=0
interface-name=eth0
permissions=

[ethernet]
mac-address-blacklist=

[ipv4]
dns-search=
technique=auto

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
technique=auto

[proxy]


[connection]
id=02STATIC
uuid=5db0c823-bc0c-4a0a-8889-2fe4256920bc
sort=ethernet
autoconnect-priority=-2
autoconnect-retries=2
interface-name=eth0
permissions=

[ethernet]
mac-address-blacklist=

[ipv4]
address1=192.168.1.71/24
dns=8.8.8.8;
dns-search=
technique=handbook

[ipv6]
addr-gen-mode=stable-privacy
dns-search=
technique=auto

[proxy]


and the pci port of my laptop computer has the next config

[connection]
id=Kabelgebundene Verbindung 1
uuid=ae4d451c-85cf-34c4-be8f-80e3e68ba950
sort=ethernet
autoconnect-priority=-999
interface-name=enp4s0
timestamp=1725874079

[ethernet]

[ipv4]
address1=192.168.1.10/24,192.168.1.1
dns=8.8.8.8;
ignore-auto-dns=true
technique=handbook

[ipv6]
addr-gen-mode=stable-privacy
technique=auto

[proxy]


The unfinished MAC deal with made me assume one thing is unsuitable with the ip configuration. I examined the {hardware} (eth cable and the port) and it really works positive. I additionally tried flushing the DNS server on the raspi however it additionally confirmed no impact.

Thanks for any sort of assist
