Hi. I have been back and forth with this, and now I am stuck.
2 identical servers, where this have worked. I moved servers to a new rack / new cabling, and now its failing on me.
Both servers are connected to a switch on trunked ports, with all VLAN's being tagged. This is working when I map virtual devices directly to the bridge.

I have validated that the config files are same.

auto eno51
iface eno51 inet manual
mtu 1500

auto vmbr1
iface vmbr1 inet manual
bridge-ports eno51
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094
mtu 1500


On one of the nodes I am getting error message in UI.
Are there any good log files to see what it is complaining about?

I have tried to create a new bridge on both servers (vmbr10) and that worked on both hosts UNTIL I mounted the interfaces.
I have tried different interfaces, and still getting the same.

Even with the error message, it looks like its working, but I REALLY want to figure out what isn't working / What is triggering error message.


Thanks

AWESOME HELP.
This brings me closer.


I have Source /etc/network/interfaces.d/* in my interface config file.

This tells me a lot. I haven't configured IPV6. I haven't configured any IP address of vmbr1 either.


auto vmbr1
iface vmbr1 inet manual [fail]
bridge-ports eno51 [pass]
bridge-stp no [pass]
bridge-fd 0 [pass]
bridge-vlan-aware yes [pass]
bridge-vids 2-4094 []
address 2620:11d:6021:2103:2a80:23ff:fea8:8f92/64 [fail]
address 2620:11d:6021:1103:2a80:23ff:fea8:8f92/64 [fail]



SDN config looks pretty straight forward.


root@SVR-DC-PX1:~# cat /etc/network/interfaces.d/sdn
#version:31

auto OAK2064
iface OAK2064
bridge_ports vmbr1.2064
bridge_stp off
bridge_fd 0
bridge-vlan-aware yes
bridge-vids 2-4094
alias OAK-2064-TME


I need to figure out why the IPV6 address is there, and how to prevent that.
 
I got this sorted out. My native VLAN had old IPv6 config on my switch. The Linux vmbr1 autoconfigured IPv6 address, and since it couldn't go anywhere it threw an error message. I removed native VLAN on my switch, I recreated vmbr1, and now its working fine. Thanks to spirit for helping me out and guiding me in the right direction !!
