Hello, My code consists of these statements,
learn.spec.append(fms( field=nx.NXM_OF_ETH_DST, match=nx.NXM_OF_ETH_DST )) learn.spec.append(fms( field=nx.NXM_OF_ETH_TYPE, match=nx.NXM_OF_ETH_TYPE )) learn.spec.append(fms( field=nx.NXM_OF_IP_PROTO, match=nx.NXM_OF_IP_PROTO )) If the last time is added then it throws an error like below, INFO:core:POX 0.2.0 (carp) is up.
