Hi Hardeep, Here is how I add multiple actions. FYI... the complete c++ file is attached. check the handle_ofentry_install() for the example Hope it works for you!
here is the partial code ----------------------------------------------- ofp_action_list actlist; ofp_action *act = new ofp_action(); act->set_action_dl_addr(OFPAT_SET_DL_SRC,srcmac ); actlist.action_list.push_back(*act); ofp_action *act = new ofp_action(); act->set_action_nw_addr(OFPAT_SET_NW_SRC, ntohl(bom->nw_src)); actlist.action_list.push_back(*act); ofp_action *act = new ofp_action(); act->set_action_output(output_port, 0); actlist.action_list.push_back(*act); ofp->init_flow_mod(of_raw, actlist); ofp->set_flow_mod_actions(of_raw, actlist); ofp->send_command(of_raw,dpid, false ); ----------------------------------------------- BTW, the sequence of actions does matter.

If you have, can you post an example in c++ showing how its down. My method make the openflow switch throw errors about the packet it receives from Nox.

I would recommend that.
