Hi, do you use Mininet to emulate network devices? If yes, Interface used by Mininet is OvS(open V Switch, is the interface to communicate with controller) isn't aware of specifics of mininet, as bandwidth, that get features of links from kernel and not from script python. So you can't modified these, infact try ; mininet> dpctl dump-ports-desc current: 10GB-FD COPPER speed: 10000 Mbps now, 0 Mbps max

So if we shape the link bandwidth using command tc like this (sudo mn --controller=remote,ip=192.168.57.1,port=6653 --topo=tree,depth=3,fanout=2 --switch=ovsk,protocols=OpenFlow13 --mac --link tc,bw=1000) we are able to find out the links bandwidth ?
