Can you elaborate on what is not transparent about 802.1q bridge in Linux?
I hear you on the system tuning. Whenever I change sysctl variables I always include a comment with what the default was and why the new setting is better. I don't trust sysctl copy pasta w/o decent explanations.

- c0l0 2y agoThere's a number of "special" Ethernet addresses that a proper Ethernet bridge must never forward. The Linux bridge implements a mechanism to ignore _some_ of these constraints, but not all of them. If you ned that, you can always get to manual patching in https://github.com/torvalds/linux/blob/d42f7708e27cc68d080ac9d3803d27e86821d775/net/bridge/br_input.c#L348 https://github.com/torvalds/linux/blob/d42f7708e27cc68d080ac... et al.
- dfc 2y agoThank you for your reply. I have had some weird issues with Linux bridges in the past and now I'm wondering if this could have been the culprit.
