I have a 10G trunk between two sites that carries 5+ VLANs on it. I have 2 VLANs that must always get through (very low volume, around 4Mb/s) but is constantly being dropped as my other VLANs are trying to push 10G or greater over the pipe. I don’t mind problems with the other vlans dropping packets, but I need these two to always get through.
Unfortunately I can’t tag specific packets easily as I can’t define the traffic that goes over the trunks (note that the trunks are also being passed via multiple 10G radios of three different mfgs so I can’t even get consistent methods of dealing with QoS) so rather than fight the radios, I just want the feed in and out at each end of the pipe to always put in traffic from these two VLANs and then prioritize the others however…
