Cool! I note it seems you are running an older flent version (or = maybe even before the big rename, so netperf-wrapper). I think current = flent includes enough improvements to merit a switch; I especially like = =93--remote-metadata=3Droot@gw.home.lan=94 option to collect some data = from the DUT automatically and save these into the output file, making = it easy to answer a few question about the configuration used a few = days/hours after the fact).=20 Also I want to note that if you shape ethernet you should use = the link layer adaptation built into sqm (configurable via the GUI): = Select Ethernet with overhead and specify the overhead to be: 24 Bytes = (ethernet pre-amble & interframe gap & FCS, Linux will have already = accounted for MACs & frame type 14 bytes, you may need to add vlan tag = (4 additional bytes)). >=20 > I'm happy to run any other tests if there is something specific = desired. >=20 > Note: I deleted the previous files I shared since they were bogus. Ah, that got me confused, I see the new files just fine. Best Regards Sebastian >=20 > I'm going to start playing wire wireless next. There's noise in the = forms that it may not be working very well but its mixed in with = 1200/1900AC so its hard to know how much applies to the ACS. >=20 > --=20 > Richard A. Smith
