### Wrong topology with extra links on Yang UI with physical switch

Hi, I am using physical switches and ODL Baryllium version. I am using a simple linear topology with 2 switches and two hosts. With these physical switches and hosts, I am getting the wrong topology somehow forming the loops with hosts on YangUI. The hosts at the end somehow get connected to the other switch to form a loop.

My Physical connection is like:

H1 --- S1---S2---H2

whereas on YangUI this topology forms a loop with extra fake links between other switch and host.

  S1


H1 . . H2

  S2


I'd appreciate some help to find the reason behind this.

Thank you
