A bridge and a switch are the same thing. I don't understand the
distinction that you are attempting to match.
There are various ways to make 2 bridges communicate, but it's usually
better to just use a single bridge.

Hmmm.. ok.. but a bridge in openvswitch can be assigned an ip address right,
unlike a switch? Also, is there a way to get 2 bridges on the same machine
to communicate to each other?
Thanks,

Hi ben,
Thanks for your input. I was confused because as you said, the man page
suggests all the connection methods, but when i use for eg:
ofctl show br0, it is connecting to a bridge right? A single openvswitch can
also have more then one bridge, so in that case, if I want to connect to the

Great, I will look into it. Thanks four your help Ben! :)

We're doing some large-scale quality of service experiments on EC2
using OVS. Since we do not have access to the hypervisor, we are
forced to run it within a virtual machine.
Basically, we would reassign the IP address delegated to eth0, to
OVS's internal interface. This works fine with ofp_a

In that case, I'll redirect my question to openflow-spec
This sounds like a pretty elaborate way to go about things. I don't
really understand the solution. Here's a simpler workaround: use the
NXAST_SET_QUEUE Nicira extension action to set the queue, followed by
OFPAT_OUTPUT to send the packet.

Please read the ovs-ofctl manpage. It explains all the allowed forms
at the very top.
Of course a Unix socket doesn't work on another machine. Add a
"ptcp:" controller to access OpenFlow over TCP from another machine.

Hi Ben,
That is correct. Right now, I am doing it from the same machine running
vswitchd. The ofctl doc says the argument should be show *switch*
and the methos of connection seemed to me like I need to give the switch
argument as unix:... or tcp: . Is my understanding wrong? (is it
different
It sounds like you want to use ovs-ofctl from the same machine running
ovs-vswitchd. There's already a unix socket for that. Just give the
name of the bridge, e.g. "ovs-ofctl show br0".

Hi Ben,
Passive tcp socket should be fine. I know the ptcp option lets you do this.
But I am not sure which command to use it with. For eg: I use the unix
socket option with ovsdb-server command so that vswitchd can connect to teh
database server. Now, ofctl needs to connect to the switch. So, whi

Do you want to
Hi,
The ovs-ofctl uses either a unix socket or tcp port to connect to the open
flow switch. When I start the openvswitch process, which command do i use to
set the switch in the listen mode so that ofctl can connect to it?
Thanks,
Aish

Hi Jesse and openvswitch team,
Thanks for all your suggestions till now. I was able to establish the gre
tunnel between 2 vms located on the same subnet on 2 different hosts. I am
not able to figure out the configuration steps to establish the gre tunnel

There is one in the OVS 1.2 software switch.
In the (not yet released) OVS 1.3 software switch, there will be 255.

Hi All,
I would be happy, if some one clear the following points.
1. How many tables are there in OVS?
2. What is the main difference ( in terms of table structure) between kernel
space table Vs user space table?
What are files some one will look at for user space table.
3. Why we need more
Hello,
I was wondering if someone could help me with a specific issue that I
have ran into. I'm running a virtual switch with two interfaces:
system@sw:
lookups: frags:0, hit:296581, missed:355, lost:12
flows: 0
port 0: sw (internal)
port 1: tap0
All I'm doing here is forwarding traffi
