capAX lost internet connection after power outage [solved]

Sat Feb 10, 2024 7:47 pm

Hi, today I had a (self made :( ) power outage...The servers are UPS powered, but my switches and recently installed CapAX aren't.
LAN is back in operation, clients have internet access.
However the issue I am facing now is: none of the clients (smart phones) connected to the CapAx, can connect to the internet.
Also I get this strange message, where IP .171 is the CapAX and .43 is my admin PC.
ether1: bridge RX looped packet - MAC 48:a9:8a:e4:fe:bd -> 90:1b:0e:aa:b2:92 ETHERTYPE 0x0800 IP TCP 192.168.178.171:8291 -> 192.168.178.43:51809
I did reboot my CRS326 (acting as switch behind ISP router) as well as the CapAX, also restored my latest CapAX backup but w/o success.
If I did change something after my latest backup I do at least not remember :? .

No idea if/what I messed up.
Running out of ideas, need a break, hoping for help.
Thanks a lot !

Not sure what to make from that message...

Try to remove Mac on bridge and set it to auto.
Possibly crs326 has the same mac address ?

Or one way or the other a loop ( which would surprise me with cap ax only having 2 ports, you would see that immediately).

Root cause found. It was a faulty Netgear switch to which the CapAX was connected to. Maybe it blew up caused by the outage.
Replaced it by another switch, all good now. Will have a good sleep now, all family gizmos are working. :)
Lessons learned...I immediately have to update my system documentation...didn't have this switch in mind, was focused on the new equipment only.
