If by 'outside' you mean 'to the extreme left or extreme right' that was my conclusion. But the absence of any documentation means this makes debugging with tcpdump (for instance) harder because you don't know where you are sampling. I'm not 100% sure it is completely outside though. For instance, if you do tcdump on a bridge device (as opposed to the corresponding physical participant interface), isn't that after ingress ebtales processing, but before egress? IE is in the graph somewhere. -- Alex Bligh _______________________________________________ Bridge mailing list Bridge@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/bridge
