Hello Does anyone know why OVS controller uses Nicira extension flow mod PDU when installing the following flow?
ovs-ofctl add-flow tcp:10.25.144.146 "in_port=21,dl_type=0x86DD priority=32768 action=output:11" I see that the verbose output contains "2013-04-18T15:20:41Z|00006|vconn|DBG|tcp:10.25.144.146:6633: sent (Success): NXT_SET_FLOW_FORMAT (xid=0x2): format=nxm" suggesting that it is indeed using Nicira extensions How can I generate only Openflow 1.0 format PDU? I actually tried using the below command but got an error labuser@labuser-desktop:~$ ovs-ofctl --flow-format openflow10 add-flow tcp:10.25.129.5 "in_port=4,dl_type=0x86DD action=output:2" -v ovs-ofctl: flow cannot be expressed in flow format openflow10 (flow format nxm or better is required) Not sure if it is not supported with openflow 1.0 format. If that is the case, can anyone justify why it is not supported with Openflow 1.0? Thanks Nagi
