- ODL L2 project
Re: ODL L2 project

Sorry for the delay. I modified the L2Switch not for fixing bugs, but for improving it. The original L2Switch uses spinning tree to flood every packet on the network, which is not effective. And ODL does not have a service to provide routing information. So basically what I did is:
1. Replace spin tree with shortest path algorithm to build a p2p flow between two hosts;
2. Add APIs to provide routing information.
An issue is that openflow-plugin, a module what L2Switch depends on, has some bugs. So L2Switch may not compact with every switch. I'll try to solve your problem by reading the spec of Dell Z9100 and the docs of openflow-plugin.
Can you please let Azher know the issues that you fix in l2switch?

Problems with real switches can always be hard to debug. We
do not have this mentioned switch, and hence it is great to
know about this issue. I feel that such issues can be
addressed by a more robust l2switch module, which we can
propose to l2switch, make sense?
I agree. This specific issue seems to be related with just the Dell
Z9000 only. This has the OpenFlow implementation but code is only
under maintenance. So hopefully Dell will release some upgraded
firmware to get this fixed.
I remember you mentioned some of the code improvements in l2switch,
can you please list the bug fixes or improvements you have made ?
We are getting ready for the SC15 conference and the current arp
manager of the ODL has issues, and it would be nice to have a better
error free l2switch from you. Please let me know.
