Hi Iwase,
I sorted out the problem now only three switches join the Ryu stp, for which I
have specified the dpid's.
But they are still being disabled.
I can't figure out why.
Any insight or solution?
Mit freundlichen Grüßen / Best regards

Please refer to the following.
This example is for OpenFlow1.4, but similar to OpenFlow1.5.

Hi
Simple switch can't handle link failure, to handle that, we can add hard
timeout to every flow entry.

I can not say "Yes" with confidence.
I think it's depending on your topology including the two extra switches,
because they are connecting to th

Hi Iwase ,
Thank you for your prompt reply. Yes I'm talking about those dpid's.
As I said before I have 3 OVS switches running on three separate machines and
all of them are connected to the controller running on a different machine
through a normal switch.
I think this switch is the reason wh

Is it possible to dump information to find out which of the ports of the
switches are connected to the host and which are connected to other switch?
I dont want manual interpretation. But some direct information stating, say

I figured out that in order to print the links information, I should use
--observe-links when executing this script. Now the information about the
links is printed.
But I still need a way to print out which interfaces of the switches are
connected to the host and which to the other switch.
Thank

Thank you Tseng. It helped me to extract information about the topology,
though in my case information about the links is not printed.
Also, Is there any way to find out which interfaces/ports of the switches
are connected to the hosts and which to other switches?
