Interconnection of Mininet-WiFi to ONOS Controller
xuankeyu opened this issue · 27 comments
Dear all,
I don't know if anyone can help me to fix this problem, but if you have idea on it, i am glad to discuss with you.
The problem is i want to use ONOS Controller as my remote controller. When i use this command to create a simple topology with onos controller:
$ sudo mn --wifi --topo linear,4 --controller remote,ip=127.0.0.1 --switch ovs,protocols=OpenFlow14
it shows that i can connect the switch to remote controller, but if i pingall, it shows that 100% dropped. And nothing shows up on ONOS GUI.
However if use such command to create a topology:
$ sudo mn --topo linear,4 --controller remote,ip=127.0.0.1 --switch ovs,protocols=OpenFlow14
It successfully connect to the remote controller, if i pingall, it shows that 0% dropped. And the topology shows up on ONOS GUI.
I have no idea why such situation happend and how to fix it. Please give me some advice if you know something about it. Thanks a lot.

Dear Ms.Fontes,
Thanks for your prompt replay.
According to you suggestions, i think i should change 2 things. First i should delete --switch ovs,protocols=OpenFlow14 in command, then only keeps:
$ sudo mn --wifi --topo linear,4 --controller remote,ip=127.0.0.1
And second i should disable NetworkManager to make sure that stations can associate with Access point. Is that correct?

OpenFlow will be used by default - you are only setting the version you want to work on.
And second i should disable NetworkManager to make sure that stations can associate with Access point. Is that corre
This is the first step. As I said, please make sure that stations are associated with APs and run it in verbose mode if necessary
Dear Ms.Fontes,
I have stop NM like this
And i use command like:
$ sudo mn --wifi --topo linear,4 --controller remote,ip=127.0.0.1
But it's still not working, it has 100% dropped.
What about associations??
Dear Ms.Fontes,
I test them. They looks good.
You are pinging to localhost! :( where is the information about the associations??
Dear Ms.Fontes,
I'm sorry that i am rookie on this. Where i can find information about associations or how can i find it?
Dear Ms.Fontes,
I am sorry for disturbing you so late, i am now reading your e-book and follow the steps from it. And i get a problem: once i disconnect the sta1 from ap1, i cannot connect them again by using:
sta1 iw dev sta1-wlan0 connect new-ssid
Let me explain it in detail. First i create the simplest topology and i check the association between sta1 and ap1, then i disconnect sta1 from ap1 and check association again. It shows that they do disconnected. And i want to connect them again and check the association with command:
mininet-wifi> sta1 iw dev sta1-wlan0 connect new-ssid
mininet-wifi> sta1 iw dev sta1-wlan0 link
It shows they are not connected.
I tried many times but it always likes this. I am really confused with this. Could you please tell me why this happend?
What if you run the iw command in debug mode? You can also perform a network scanning. Unfortunately, you provided no information that may help me to comprehend what is going wrong.

Dear Ms.Fontes,
i have found the reasons. I should connect my-ssid instead of new-ssid. And it also needs a couple of seconds to process. then the link information will show up again
What about associations??
Dear Ms.Fontes,
I want to be back to my original question. I stopped NetworkManager and check the association. The result is they are associated correctly, which means sta1 associate with ap1, sta2 associate with ap2 and so on.( the screenshot is the result by mininet-wifi> sta1 iw dev sta1-wlan0 scan).
But i can still not connect such network to ONOS Controller. I am really confused, could you please help to find the reason?
Thanks so much.

Did you set ONOS as remote controller?? This seems a tcp/ip issue.
Dear Ms.Fontes,
i am sure that i have set ONOS as remote controller. The reason is when i use ONOS to control a Mininet network sudo mn --topo linear,4 --controller remote,ip=127.0.0.1 --switch ovs,protocols=OpenFlow14, it works well. But if i just add --wifi in the command, it cannot work.
Like you said, i also checked the ip. This screenshot is the last line when i run ONOS controller. It shows that ONOS works on ip:127.0.0.1
And then i set up a topology with remote controller on 127.0.0.1
Nothing shows up in ONOS GUI with ip 127.0.0.1:

You can see nodes through the GUI because there are ethernet links among aps
Nothing shows up in ONOS GUI with ip 127.0.0.1:
This doesn't mean that the AP is not connected to ONOS. Since in-going and out-going interfaces are the same you may not notice that node through the GUI. You should confirm the connection between AP and Controller via OVS utilities! This is a issue that has already been widely discussed on the mailing list.
Dear Ms.Fontes,
I tried pingall, it said 100% dropped and then i checked the association between each station and access point, the result is they are associated perfect. So in my opinion, the error can only occur between AP and ONOS.
Dear Ms.Fontes,
I also tried to set up a topology using Miniedit, with onos controller, 2 APs and 2 stations.
it works perfect and when i pingall, nothing dropped.
So why it can work in Miniedit but not with command line?
I tried pingall, it said 100% dropped and then i checked the association between each station and access point. So in my opinion, the error can only occur between AP and ONOS.
I don't think so. ONOS has no influence on the simple topology. In other words, ONOS will not influence anything! If there is no association between ap and sta you have to run the command in debug level and see what is going wrong.
Dear Ms.Fontes,
But it has associations between APs and stations...
How can I reproduce the issue??
Dear Ms.Fontes,
use bazel to install an ONOS controller. And run it by following such step1 and step2 in (Running ONOS and Mininet separately (Succeeded!))[https://ernie55ernie.github.io/sdn/2020/07/21/setting-up-onos-controller-with-mininet.html]. Then typ sudo mn --wifi --topo linear,4 --controller remote,ip=127.0.0.1 --switch ovs,protocols=OpenFlow14 in another terminal. At last, try pingall.
Which OpenFlow version are you using with miniedit?? Did you run both (code from miniedit and the command line) in debug level???
Dear Ms.Fontes,
I tried OpenFlow 1.0 and 1.3, both of them works well.
No, but how to run both in debug level?
I tried OpenFlow 1.0 and 1.3, both of them works well.
So, isn't the problem the OpenFlow version you are using?? ;/
No, but how to run both in debug level?
Dear Ms.Fontes,
I don't think it is an OpenFlow version issue, because i have tried version 1.0, 1.1, 1.2, 1.3 and 1.4. None of them work. But i tried them on my now topology which directly run on Miniedit, All of them can work.
Here is my attmpt to dubug:
