Hi guys, I am using Mininet to do my testbed setup and I am using Open vSwitch in my topology, so far I've managed to create a topology and I've already put my NOX plugin to work, now I'm willing to do some QoS tests but I am having some problems to add queues to my OVS switches. I've tried to use the dpctl command as it follows: dpctl add-queue tcp: 127.0.0.1:6634 3 1 2 And then this output is shown to me: made request 0x9af8048, running transaction
But when I do the queues listing nothing is shown: sudo ovs-ofctl queue-stats tcp:127.0.0.1:6634 OFPST_QUEUE reply (xid=0x1): 0 queues sudo dpctl dump-queue tcp:127.0.0.1:6634 3 error_msg (xid=0x23f0be85): type1(OFPET_BAD_REQUEST) code1(OFPBRC_BAD_TYPE) payload: Unknown OpenFlow packet type 20: 00000000 01 14 00 0c 23 f0 be 85-00 03 00 00 |....#....... | stats_reply (xid=0x3c251c68): flags=none type=5(queue) And this is how Mininet creates OpenFlow switches: ovs-openflowd dp0 tcp:192.168.1.139:6633 --fail=secure --listen=ptcp:6634 --datapath-id=0000000000000001 ovs-openflowd dp1 tcp:192.168.1.139:6633 --fail=secure --listen=ptcp:6635 --datapath-id=0000000000000002 Also it's important to note the version of the Open vSwitch is 1.2.2.
