Hi Subhash, Thanks for replying. I tried it but it worked only for MAC Address. When I'm giving IP Addresses, it's not wokring. flow dump is for blocking icmp: cookie=0xa, duration=1.726s, table=0, n_packets=0, n_bytes=0, priority=6200,icmp,nw_src=10.0.0.1,nw_dst=10.0.0.2 actions=drop

just remember that if you adding any rule based on the IP address then you must fulfil the prerequisite of match i.e. if you have match on ip address then there should be match on eth_type = ip.

Oh yea.. It worked thanks..:) Also, if have any tutorial or could provide me with anything that could help me with SFC implementation, it'll be great. I've understood the concept behind it, but I'm not able to implement it.

You are welcome :) Could you please accept the answer if the answer helped you, so that other can also refer the answer. !!

Do you plan to use SFC only for firewall? If yes, it seems like overkill. Why not consider writing your own firewall application? It would be a good way to familiarize with ODL as well as get what you want out of it.
