Re: [Bloat] About Setting Bandwidth limit with or without ethernet overhead?

[Y <intruder_tkyf@yahoo.fr>]

Hi , Dave
Thank you for your reply.

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.
