I should show you tc-stab setting. My connection is PPPoA via ethernet. PC connects ethernet directly. ####stab linklayer atm overhead -4 I add PPPoA overhead 10 + Ethernet overhead -14 = -4 But, settled Bandwith is 98% of link speed ( I mean this is settled bandwidth without ethernet overhead). I should shape more? Thanks.
