Hi,
which switch are you using? i had the same problem earlier this week
with the userspace implementation. There is already a workaround for
that issue in the main branch of mininet. just update via git.
Reagrds,

Hi All,
While using Mininet to setup link properties like 'BANDWIDTH' using
TCIntf for a link between interfaces, I am facing some issues. Need to
clarify the same. My topology is as shown below.
_*Flows:*_
Host1 - Host4
Host2 - Host5
Host3 - Host6
I set each of the link capacity as 1Mbps using *"self.addLink(switch1,
switch2, bw=1)"*
When I send traffic 'simultaneously' on all the 3 hosts using iperf,
each flow shows Bandwidth of 1Mbps. Since the link bw between Switch1
and Switch2 is set as 1Mbps, I expected the sum of the bw of the 3
flows will give me 1Mbps. But I observe that each of the flow gives a
bw of 1 Mbps making the sum to be 3Mbps, when I had set the link bw
between Switch1 and 2 to be just 1Mbps.
Please clarify me on this regards, Thank you.
