Hey Srikanth, You are not getting any classification rule because it can't find an RSP, which means it was not able to create the chain. There is something fishy going on and it should not be there if you do a complete restart of ODL. To completely restart ODL, you must stop it, remove the directories: snapshot, instances and journal. Then, you should restart the OVSs (removing their conf.db database). If you are using neutron v2, you must also restart neutron completely (database included) because it keeps a journal and what breaks ODL, will again be executed as soon as neutron detects that ODL is up.
