Hi all:
I maintain the SDN Hub tutorial VM. I updated the OVS to the head of the
repo and did the test that Yikai is trying. I didn't see any MPLS tagged
packets being sent out either. Here's a bit more info on my environment and
some error I see in the logs:
*$ ovs-vsctl --version*
ovs-vsctl (Ope
I posted this question on mininet-discuss mail list and they insist that
it is an open vswitch question.
why do the port numbers assigned to an interface (say s1-eth2) change
when linux system is rebooted?
Is there an ovs-ofctl or ovs-vsctl command I can use to force/change the
switch port n

Q: Does Open vSwitch support OpenFlow meters?
A: Since version 2.0, Open vSwitch has OpenFlow protocol support for
OpenFlow meters. There is no implementation of meters in the Open
vSwitch software switch (neither the kernel-based nor userspace
switches).

Are you using datapath in kernel or in userspace?
What's the kernel version?
If it's kernel DP, then patch ports are internal ports which during TX
inserts the packet (skb) into the CPU backlog queue (enqueue_to_backlog())
for later processing. Later on, the backlog queue is processed

Hi,
When I send Modify meter message or Modify flow entry message with meter
instruction, OVS always answers OFP errer msg with the reason
"OFPET_METER_MOD_FAILED".
I think the parameter of Modify meter/flow entry msg is right. But I don't
know why OVS answers this cause?
Need I do many meter conf
Thanks a lot.

Correct.

You could write flow rules in such a way to preve
There's no drop. The packets should have wondered somewhere. Find it :D
You set this up by a py script or manually? If not entirely by a script
which you surely have check, than I'm skeptical of a mistake. But
anyway, another suggestion is: manually delete 66th and link 65 with 67.
See if it's
Idea is to send any destination to a specific host.

Or do we have any other option to avoid loops.

Please don't drop the list.
Open vSwitch does not have such a check.

TTL doesnt seems to be the problem. i have considered that. anyhow if
you check the traffic in the output that i posted the TTL is set as
255. Also i dont think TTL should matter if we are forwarding packets
at layer 2.
I am guessing there is a check somewhere in OVS code which limits it.
if anyo
So I tried to do this on 12.04 and got the following error when installing
OVS, any insight on how to fix this?
Thanks Gil

Dear,
Time to live behavior? Just my sense. I'm not very into this to be sure.
You can see from wireshark if it's really because of TTL.

Hi,
I am trying to create a linear topology of 70 switches and linking all

packets in the first switch(S0) and I have added flows on all of the
switches to forward the packets in one direction towards the last
switch (S69). I am u

No, you must enable it.

Thanks Ben for your contact!
I suggest some kind of customization at ofproto provider, allowing to
choose appropriate table to install each of the in-band flows, maybe at
rule_choose_table or rule_construct.
Thanks!
