"kernel: arp: 43:05:43:05:00:00 is multicast" spam in syslog
I have a small network with pfSense running on an APU1D and an Open-Mesh WAP (OM2P-HSv2) attached to the LAN switch. In the syslog are endless "kernel: arp: 43:05:43:05:00:00 is multicast" messages every few seconds. 43:05:43:05:00:00 does not exist in my ARP table. My research didn't turn up much but points to this being a side effect of something called Bridge Loop Avoidance Protocol that the openmesh folks have built in for their mesh networking (sort of like Spanning Tree but designed for lossy links)
I didnt' see any way to disable this feature on the WAP side so I was wondering if there was a way to block these (harmless) messages from the syslog?

Saw that option but was scared to enable it. Seems a bad idea to violate the RFC. But I am testing it out now - so far seems to be working. Thanks :)
I don't think you'll see an issue. That was the behaviour in 2.1.5 anyway but 2.2 tightened it up.
Ah that makes sense. Was running 2.1.5 on this unit until recently and never noticed the messages before. That explains it, thanks guys
