    How to do packet packet from a particular port in the BCM switches.

    I will explain my scenario, we have a Hw that is having BCM as switch fabric, so packets from switch fabric are forwarded to a controller, but there we are observering some discards. We donot know what is the reason for the discards, and what those packets are. If we could able to capture packets in the bcm port, we could able to identify the reason for discarding and the packet.
