Hi, I currently have a review in to make carp use dscp values on outgoing packets. This will make it easier to preform QOS on modern switches as we have been able to drive carp insane on 10g links while throwing storage traffic at it.On an interesting side note apparently after 64k mac address moves for a single mac address in the cam table arista 7050t seems to with out warning give up and stop moving address but leaves it in the table where ever it last was.
I was originally going to just toggle between cs7 and the old TOS low delay setting. But it was requested that I just make it a settable Integer value. In this case I'm planning to do 0-63 to match dscp with a default of 54 (CS7) (Network Control) but you could still set the old value by setting the sysctl to 4. Anything larger then 64 would be truncated as two shifts are needed to align with the field leading. Does anybody do anything anywhere with the old TOS values like low delay in there networking infrastructure? Should this be updated in other places in kernel and userland? It's been 20 years since TOS was deprecated and replaced with DSCP. Any other comments or thought are always welcome.
