Thank you Junaid Khalid and Murphy!
I just got this from pox.openflow.libopenflow_o1
ofp_flow_mod_command_rev_map = {
'OFPFC_ADD' : 0,
'OFPFC_MODIFY' : 1,
'OFPFC_MODIFY_STRICT' : 2,
'OFPFC_DELETE' : 3,
'OFPFC_DELETE_STRICT' : 4,
}
I am not getting clear how do I use it in flow-mods. Please refer me to
some example for it. Thank you for your guide and help. Thanks a lot!
