Dear Airheads,
We have a Chromecast setup implementation in customer location. The Chromecast team connected a Mikrotik Router on the core switch (Aruba 5406). We noticed that the switch port starts flapping (stp blocking). Then we confirmed that the STP is disabled on the Mikrotik router and configure the switch port as below. But still the port is blocking by STP.
Please suggest.
