ARP: X is multicast
At sites where I have OpenMesh devices, I repeatedly see
arp: xx:xx:xx:yy:yy:yy is multicast
How can I silence these in the logs? I've seen this:
Is this still the solution?
Yes, that's still technically invalid so needs to be specifically allowed:
Thanks. In looking at the redmine I see a recommendation to add it into System->Advanced -> Network. In there I see:
ARP Handling _ Suppress ARP messages This option will suppress ARP log messages when multiple interfaces reside on the same broadcast domain.
Will checking this box effectively do the same thing? Or should I add it in as a Tunable?
No, that will not accept the multicast ARP replies if you need that. That requires the system tunable to be added.
If you just need to clean the logs then you can try that check box. I'm not sure I've ever done so for multicast ARP, we hardly ever see that (because it's invalid ).
