bridge port received packet with own address as source address...loop

Sun Nov 14, 2021 11:51 am

Hello,
I have a big problem, since I bought a Crs326-24G-2S that I added to my CRS305-1G-4S+IN, my network is failing. In the logs I have continuously "bridge port received packet with own address as source address (mac), probably loop".
I did not touch the configuration, the CRS 305 works perfectly without CRS 326. They are powered in 10 GB via SFP+. No VLAN...

Re: bridge port received packet with own address as source address...loop

Mon Nov 15, 2021 11:41 pm

Wait one, where is the ISP in all of this, I see two switches pretending to be routers.
If you have not ISP connected to either one, where is the router?
what is the router providing?? DHCP services? anything.

Hello, it is my Free router that manages DHCP.
I think I found the problem, a third Netgear 8 port switch that seemed to be defective. Since I replaced it, no more problem.
