CBENCH EMPTY RESULT [NOT learning destination mac addresses before the test]

[JodiTan]

Hi,

i tried to run cbench in my pox controller as follow :

sudo cbench -c localhost -p 6633 -l 5 -M 5 -s 6 cbench: controller benchmarking tool running in mode 'latency' connecting to controller at localhost:6633 faking 6 switches offset 1 :: 5 tests each; 1000 ms per test with 5 unique source MACs per switch NOT learning destination mac addresses before the test starting test with 0 ms delay after features_reply ignoring first 1 "warmup" and last 0 "cooldown" loops connection delay of 0ms per 1 switch(es) maximum number of requests sent to controller per test is 2147483647 debugging info is off 12:29:28.357 6 switches: response/requests: 0/1 0/1 0/1 0/1 0/1 0/1 total = 0.000000 per ms 12:29:29.459 6 switches: response/requests: 0/1 0/1 0/1 0/1 0/1 0/1 total = 0.000000 per ms 12:29:30.561 6 switches: response/requests: 0/1 0/1 0/1 0/1 0/1 0/1 total = 0.000000 per ms 12:29:31.667 6 switches: response/requests: 0/1 0/1 0/1 0/1 0/1 0/1 total = 0.000000 per ms 12:29:32.767 6 switches: response/requests: 0/1 0/1 0/1 0/1 0/1 0/1 total = 0.000000 per ms Total Count: responses/requests = 0/30 Total Average: responses/requests = 0.00/6.00 RESULT: 6 switches 4 tests min/max/avg/stdev = 0.00/0.00/0.00/0.00 responses/s

for the controller result :

and for the mininet : sudo mn --topo single,3 --mac --controller remote --switch ovsk [sudo] password for joditanato: Creating network Adding controller Unable to contact the remote controller at 127.0.0.1:6653 Connecting to remote controller at 127.0.0.1:6633 Adding hosts: h1 h2 h3 Adding switches: s1 Adding links: (h1, s1) (h2, s1) (h3, s1) Configuring hosts h1 h2 h3 Starting controller c0 Starting 1 switches s1 ... *** Starting CLI: mininet> h1 ping h2 PING 10.0.0.2 (10.0.0.2) 56(84) bytes of data. 64 bytes from 10.0.0.2: icmp_seq=1 ttl=64 time=3.06 ms 64 bytes from 10.0.0.2: icmp_seq=2 ttl=64 time=0.231 ms 64 bytes from 10.0.0.2: icmp_seq=3 ttl=64 time=0.040 ms 64 bytes from 10.0.0.2: icmp_seq=4 ttl=64 time=0.044 ms 64 bytes from 10.0.0.2: icmp_seq=5 ttl=64 time=0.069 ms ^C --- 10.0.0.2 ping statistics --- 5 packets transmitted, 5 received, 0% packet loss, time 4084ms rtt min/avg/max/mdev = 0.040/0.689/3.064/1.189 ms mininet>

i can successfully ping from h1 to h2 but it seems like cbench can't learn destination mac address and the result is empty. I wonder why the cbench can't learn the destination mac.

Thanks
