openflowplugin oxygen-stable couldn't get links

Mingming
 

Hi Jamo,

Thank you! Now I got a update. After tried for more times, sometimes I got links with openflowplugin, sometimes I did not. So is this a unstable problem? But h1 ping h2 still doesn't work. 

Another problem which I think is more important: I still can get nodes (http://172.16.129.1:8181/restconf/operational/opendaylight-inventory:nodes/) when I shutdown mininet. Just links in topo (http://localhost:8181/restconf/operational/network-topology:network-topology) are gone. If so, I can't notice node failure. In other words, I can't figure out disconnections happened in "switch to controller" or "switch to switch" just by checking link status in topology.

I think operational data store means get the sync info from switches. config data store means odl configuration information which is fine to keep records when switches are gone. 
I really want to catch up with latest odl so I could do something on it. Thank you for your help!


Best regards,
Mingming

adding the openflowplugin-dev list as I think there will
be more people reading that to help you.

I met a problem: I couldn't get links using "http://localhost:8181/restconf/operational/network-topology:network-topology" <http://localhost:8181/restconf/operational/network-topology:network-topology",>, but other info like topo-ids work well.

Besides, I have done some works trying to figure out the problem. According to:

feature:install odl-openflowplugin-app-lldp-speaker-li
"
There should be "odl-openflowplugin-app-lldp-speaker-li", but I didn't find it. I have read code as well. Is it the one called "odl-openflowplugin-app-topology"? I saw some lldp dependencies in it.
Another problem is that port 6633 will stop being listening if I "feature:installed featuers-openflowplugin and features-l2switch".
Did I make some mistakes so I failed? Or there are some designs here? Really need your help! Thank you!

Hi all,

Recently, I am working on openflowplugin oxygen-stable. I met a problem: I couldn't get links using "http://localhost:8181/restconf/operational/network-topology:network-topology", but other info like topo-ids work well. As a result, h1 ping h2 (mininet) couldn't succeed. However, links are shown in topology when I use l2switch. 

Besides, I have done some works trying to figure out the problem. According to: 
"

feature:install odl-openflowplugin-app-lldp-speaker-li
"
There should be "odl-openflowplugin-app-lldp-speaker-li", but I didn't find it. I have read code as well. Is it the one called "odl-openflowplugin-app-topology"? I saw some lldp dependencies in it. 

Another problem is that port 6633 will stop being listening if I "feature:installed featuers-openflowplugin and features-l2switch".

Did I make some mistakes so I failed? Or there are some designs here? Really need your help! Thank you!

Best regards,
Mingming
