Re: [nox-dev] working of switch api on link failure

Hi,

Pardon my laziness in not reading the patches.  I am confused here.  Two points:
1) Switch does not depend on topology or discovery, so how do you get
link failure?

2) There is no spanning tree implementation in NOX (distributed by
default), i.e., you cannot have a redundant network with NOX.  So, how
can you possibly hope to find the host on a different route when a
link failure occurs?  On that note, why does handling link failure
even matters?

KK

 Hi Sachin
 You raise a good point. There is no code that performs the needed
 cleanup on link failure. I've attached two patch files that shud work
 for the switch module and the routing module. This will clear the flow
 rules on the switch for that out_port that went down, and also clear
 any learned MAC address (in case of the switch module).

 The code is not necessarily optimized. But, it has been tested to work
 fine with HP switches in a small lab setup. Please let us know whether
 this solves your problem.

  when i run nox with this switch api then flow entries are getting added in
 openvswitch. But when I make one of outgoing link down. then after some
 time, older flow entry gets vanishes and new flow entry is getting added in
 my flow table with available port. But new entry addition time is greater
 than flow expired time ( in my case it is 50 seconds).

 But I am not able to find the code in nox which does this action on link

Oh, with switch, I use the port_status_change event and clear flow

If a silent host (connected to port X) had moved to port Y, then your
table will still think the host is located on port X. Even if there
existed a chance of reaching host thro' port Y, the controller won't
really try that.

Re: [nox-dev] working of switch api on link failure

Hi Srini,

1) The archived port would be the same port?

2) My point precisely.  So, what does clearing the flow entries achieve here?

I contend that custom controllers might want to implement this
flushing on their own.  The patch is probably most useful as a
component that other controllers can load on demand.  Patching this on
switch and routing would add to clutter with little utility in my
opinion.

Regards
KK

PS I am happy to push this functionality as a component.

Re: [nox-dev] working of switch api on link failure

2010-12-06 Thread sachin sharma

Hi Srini,

Thank you very much for the patch.

Switch.cc implements  L2  learning. But  in this patch, action are taken on 
link 
failure. This does not match with MAC learning. 


The code of switch.cc works fine. But only the issue is that it does not 
implement aging timer. 


Aging timer is explained below:

http://noxrepo.org/pipermail/nox-dev_noxrepo.org/2010-December/001845.html

I think if we implement this then MAC learning code would work well for 
protection scenarios as well.

So from my point of view,  we should not take the action on link status change.

The patch would work fine. But this could be a enhancement over MAC learning.

Sachin Sharma

Re: [nox-dev] working of switch api on link failure

Hi Sachin,

Thanks for all the heads-up.

For aging, I am a little wary about the consequence of implementing
aging.  Wireless clients (esp. phones with WiFi) tends to be fairly
silent these days.  I don't have numbers for that, but it might be
good to have some value to play with before pushing such a patch.  I
will see how I can get some of these numbers.

Thanks.

Re: [nox-dev] working of switch api on link failure

2010-12-06 Thread Srini Seetharaman

Sachin brought up a valid point that the switch and routing modules
are lacking on actions to take when a port or link goes down. Note
that the code available right now in NOX may cause packet loss if the
dst host moved to a new location and stays silent at the new location
(Ageing or host table flushing needs to be implemented for this to
work)

Whether you want MAC entries to expire like a learning switch, or
whether you want to proactively flush out entries made, is left to
you. The code for the latter is in the patch I mailed earlier.

Thanks
Srini.

[nox-dev] NoX routing does not work

Hi,

I had reported this bugs a few weeks ago, and it's not
fixed. I need to run NoX to debug the interactions between NoX and my
switch, but if NoX does not run...

Ok this is what I do :

--
$ tar -xvzf nox-zaku-10dec02.tar.gz
$ cd nox-zaku-10dec02/
$ ./boot.sh
$ mkdir build/
$ cd build/
$ ../configure
$ make -j3
$ cd src
$ make check
$ su
# ./nox_core -v -i ptcp:2710 routing


And, as soon as the first ping packet arrives, NoX just blows
up in an infinite loop of DBG messages and . See log below...

A tcpdump shows that packet are not going through at all.
When ARP is cold, I get no flow tables. When ARP was already
resolved, it seems that I get a flow entry for the ARP return path.

Note also that both the switch and the pyswitch modules

[nox-dev] NOX Router

2010-12-06 Thread Uday Kiran Medisetty

Hi,

I want to implement a router using NOX. I have a topology in which Host1 is
connected to Switch1, Host2 is connected to Switch2 and both the switches
are connected to the router. When Host1 sends ICMP packet to Host2, it will
set the destination mac address as the interface on router to which switch
is connected. Now on the router, when I see that the mac address is some as
one of it's interfaces, it will check the ip address. Since the ip address
is Host2's ip address, it has to replace the mac with Host2's mac address
and forward it to switch 2.

But on the router, after I change the destination mac in packet_in_callback,
when the packet reaches switch 2, I still see the old mac address. Please
let me know if I am missing something or if there is a simpler way to change
mac address of a packet in packet_in_callback function.

 Hi Jean
 What is the topology you're using? Do you have a loop?

This is a *single* switch. It's connected to another switch,
but that other switch is NOT running OpenFlow. Anyway, that would blow
up with my other controllers...
Now that I think of it, yes, there is a gotcha, this switch
has a LAG. I'll try without the LAG and report...

Hi,

I tried with another switch which does NOT have a LAG. This
time, it seems that the forward path is working, and the return path
does not work. And I still have the same DBG message in a tight loop.
(By the way, the -v flag does not seem to show anything
interesting for debugging).
Note, both host connected directly to the switch.

Re: [nox-dev] NoX routing does not work

Hi Jean,

I am confused you seem to be giving us partial logs and also your NOX
seems to be slow.  Are you running in a VM?  Anyway, I cannot figure
out what the problem is from all these.  I understand you have flow
setup in one way and not the other.

Can you furnish more information and probably the full NOX output and
pcap exchange of OpenFlow messages? Knowing the line number to focus
on in those logs will help too.  I understand you are a savvy user of
OpenFlow but it is hard to debug from email description, esp. when I
am not clear which is from LAG or non-LAG switch.

Thanks.

Regards
KK
