sfp-sfpplus10: bridge port received packet with own address as source address (#mac of my cAP AC#), probably loop
every 5 seconds in my log.
I have one single cable running directly from Port 10 to my cAP AC “ETH1 PoE In” port.
Nothing is connected to ETH2
I have a mAP (Lite I think) connected to Port 6
both mAP (?Lite) and cAP AC are provisioned from my main router (CRS326-24S+2Q+) usinc CAPsMAN
What would you need to diagnose this issue?
As the CRS326 complains about own address as the source address of a received frame, the most likely explanation is that the bridge (or the sfp-sfpplus10 interface itself) on the CRS has the same MAC address like the cAP ac. One possibility is a mistake in production, a more likely possibility is a misconfiguration (you can manually change IP addreses of Ethernet ports as well as of the bridge). So I’d check this as the first thing.
The most common mistake in misconfiguring the capsman.
A loop occurs between the physical ether1 interface and the virtual CAP on the access point.
Remove the inactive wlan1 interface on the CAP from the bridge.
Thanks! For whatever reason I wasn’t subscribed to this topic and thus thought noone had answered, I have removed the inactive wlan1 and wlan2 connections from the bridge, and the messages have disappeared. Now as a side effect my cap doesn’t have an IP address anymore, but I can still talk to it usinc the MAC. sufficient for me at this time
