Mininet connecting to ONOS issue, no topology shown
Md. Mahbubul Hassan
I used the mininet command as below-
$ sudo mn --topo linear,4 --controller remote,ip=10.0.2.15,port=6653 --switch ovsk,protocols=OpenFlow13
I log in using karaf to CLI of ONOS.
The output there is as below-

However, The above mininet command connected the controller. However, I didn't have any topology shown on the web interface. Please look I used on my mininet my controller IP for the host-only ( 192.168.56.101-> url) but the device found was 10.0.3.15 -(NAT adapter).
What I am doing wrong?
Any help would be much appreciated.
Kind Regards,
Mohamamd
