Hi All. I've installed a UGREEN Ethernet Adapter and created a bridge (vmbr1). I've used it without an issue until I rebooted the host. It looks like the port is not activated after the reboot. I have to reconfigure the bridge to bring it back up. Is there something I can do to make these settings persistent after reboots? Many thanks.

Code:
Mar 09 23:28:12 pve systemd[1]: Starting Network initialization...
Mar 09 23:28:12 pve networking[736]: networking: Configuring network interfaces
Mar 09 23:28:13 pve networking[832]: error: vmbr1: bridge port enxf8e43b5aef89 does not exist
Mar 09 23:28:13 pve systemd[1]: Finished Network initialization.

Hello,

Provide us with the output of ip a command and the network configuration cat /etc/network/interfaces
 
auto lo
iface lo inet loopback

iface eno2 inet manual

iface enxf8e43b5aef89 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.20/24
gateway 192.168.1.1
bridge-ports eno2
bridge-stp off
bridge-fd 0

iface wlo1 inet manual

auto vmbr1
iface vmbr1 inet static
address 192.168.2.0/24
bridge-ports enxf8e43b5aef89
bridge-stp off
bridge-fd 0
 
Hi,

Thank you for the output for the network configuration! (you forgot to post the output of ip a command). However, did you set the IP for the vmbr1 as 192.168.2.0? is it was working with 192.168.2.0 IP or did you change it?

Thank you @Moayad . `ip a` contains quite a few interfaces from cts and vms, ideally I want to edit these out. Do you need all output or just what is relating to the 2 Ethernet interfaces? Yes, it does work with IP `.2.0`. I believe not assigning a proper IP to the bridge stops the vms communicating directly with the host, please correctly if I'm wrong.

At the moment, the interface is working as I had to reconfigure it last night. I take out the bridge port from vmbr1, apply configuration, re-add the port and re-apply configuration and it works.

The host is in use an the moment so I cannot restart it, maybe later on today.
