Thank you Durga I tried it with what you have said and I received same errors :(
It is event.dpid from pox.forwarding.l2_multi import * I want to know how to do this if statement and it body, i.e., l2 and l3 classes calls. Should l write them in pox.py statement Ok if that, how is it switch from l2 to l3, while working.
