packet received on bridge with own mac address

Wed Jan 02, 2019 10:20 am

Hi there,

I installed 2x CRS317 as a distribution / coreswitch in 2 datacentres with a vlan in between them do redistribute traffic between the locations.
The CRS at datacentre A works flawless without any errors, but at datacentre B I'm receiving the following log lines:
08:53:41 interface,warning vlan-gs-ser: bridge port received packet with own address as source address (b8:69:f4:8d:93:93), probably loop
08:55:41 interface,warning vlan-gs-ser: bridge port received packet with own address as source address (b8:69:f4:8d:93:93), probably loop
I tried to drill down the config but as far as I can see no significant errors. Besides that the CRS fully functions without errors or discards at the interfaces. Anyone willing to inspect my config and hopefully can help me out?
