Re: [LARTC] [Help] IMQ download traffic is duplicated !?
What I can tell you for sure is that it is not related to IMQ at all.
I've already experienced this traffic rate "duplication" behavior on
"only egress" shapping machines but couldn't find its source.
Anybody else?

Hi,
I have a default class for my un-marked traffic (prio 5) and a prio 0 class for the

It work fine for my upload traffic (same setting except the red class but I have the
same
result if I create an esfq instead).
Any comments/information will be appreciated.
