Hi Brandon,

e quickly read the thread (maybe too quickly)= ,
from what i remember for virtual interface txqueuelen is= 0 by default, so nothing work as expected
can you check the txqueuelen = with ip -a ?
(i've found no reference to txqueuelen in sq= m-scripts)

I haven=E2=80=99t done anything manually to change txq= ueuelen.=C2=A0 Whatever is here is default (1000 on eth) or I assume set by= sqm-scripts / tc (32).

I believe this is the output you are = looking for:

=E2=80=94

=E2=80=94


no qlen means 0 I think
maybe tr= y
ip link set eth0.666 txqueuelen 1000
