This feature is not available in OpenFlow 1.0. So you either need to use a higher version of OpenFlow (which POX doesn't support yet and OVS only recently has gained experimental support for), or using a Nicira extension.</div><div><br></div><div>There are actually two different ways. I think for both of them (and definitely for the second one), you must first enable NXT_FLOW_MOD_TABLE_ID by sending an nx_flow_mod_table_id message to a switch. Once you've done that, you can:</div><div><br></div><div>1) Use nx_flow_mod. This is the version of flow_mod that uses Nicira Extended Match.</div><div><br></div>2) NXT_FLOW_MOD_TABLE_ID slightly modifies how normal ofp_flow_mods are interpreted, making one byte of the command field be the table ID. There's a version of ofp_flow_mod in the nicira module called ofp_flow_mod_table_id which adds a table_id field.<div><div><br></div><div>-- Murphy</div><div><br><div><div>On May 30, 2013, at 10:19 AM, Mayumi Park Campos wrote:</div><br class="ecxApple-interchange-newline"><blockquote><span class="ecxApple-style-span" style="border-collapse:separate;font-family:Helvetica;font-style:normal;font-variant:normal;font-weight:normal;letter-spacing:normal;line-height:normal;orphans:2;text-align:-webkit-auto;text-indent:0px;text-transform:none;white-space:normal;widows:2;word-spacing:0px;font-size:medium;"><div class="ecxhmmessage" style="font-size:12pt;font-family:Calibri;"><div dir="ltr">I just have a question, if I want to add a flow per table I must use de nicira extension?
