I'm sorry, but I don't all the ins and outs of configuring tc off the top of my
head. If you really want to dig into it, I'd look at functions like
htb_setup_class__() in netdev-linux.c to see what it's doing:

Hi ,
Below I am asking for HTB.

Hi Justin,
Please correct me if I am wrong,I am trying to map "vsctl" parameters with
"tc" parameters :-
*Mode* of class is artifical value which can be computed from *R (actual
rate)*,*AR(assured rate)*,*CR(ceil rate)*. Possible modes are
- *Red*: *R* > *CR*
- *Yellow*: *R* <= *CR* and *R
Thanks Justin!
just one more query -
in configuartion cookbook of OVS, you are taking measuring host as separate
machine ,can't I take my bridge (OVS) as measuring machine, because traffic
of VM coming on bridge only and we can verify throttle on bridge itself
through netperf

If you configure it through ovs-vsctl, an appropriate configuration should be
pushed down to the kernel. We don't expose as many knobs as the tc command, so
the configuration is much simpler. You should be able to verify the
configuration pushed down by using the tc command to dump classes, qd
Hi Justin,
Sorry to bother you.
I am confused because tc manual is having many paarmeters to configure,
class , handle id etc.. but in OVS we have just rate or burst.
so how we will configure parent -child through OVS vsctl?

That's what you're configuring, so OVS is taking care of the tc configuration.

Hi,
To verify HTB and HFSC on OVS ,if I am creating queue and setting rate
through vsctl command then do I need to do some configuration from "tc"
also?

The former. If you want to control the rate going into the switch from the VM,
you'd need to use a policer.

Hi Justin,
Is that mean to verify HTB and HFSC on VM interfaces , I have to create
queues on VM interface with particular bandwidth/rate and have to send
traffic from switch to VM and then check rate .
this is ingress to VM, right?
OR
after creating queue on VM , I will send traffic from VM and w

Yes, they should. We just leverage the tc's mechanisms in the kernel.

Thanks Justin!
It means HTB, HFSC and policing all would work on VM interfaces ?
Is this implementation opposite to policing because policing act as ingress
for switch perspective and egress for VM interface?

Yes. They're on egress from the switch's perspective, though, which means
they're ingress into the VM (and egress onto the wire).

Hi,
Are HTB and HFSC queueing disciplines supported on OVS virtual port (VM
interfaces) also?
