It depends on your next hop's framing. If you are on ethernet going to ethernet, then you should set ethernet. If you are on ethernet, going through a cablemodem, set docsis. If you are on ethernet, going through dsl or something else, you set the framing appropriately. Without setting the framing appropriately you can run into situations where your shaper can be 60% in accurate (dsl). > > Thanks. > _______________________________________________ > Bloat mailing list > Bloat@lists.bufferbloat.net > https://lists.bufferbloat.net/listinfo/bloat ^ permalink raw reply [flat|nested] 11+ messages in thread
