PROCESSOR-SDK-J784S4: ETHERNET portMaskDrop

Part Number: PROCESSOR-SDK-J784S4

Tool/software:

Hello,

In out application we are seeing that the host port is dropping frames to be transmitted from the SoC to the outside world due to the portMaskDrop.

Could you tell me what is the reason for this portMaskDrop and where to find additional information?

Thank you in advance.

    There might be no destination port mapped from ALE entries for the transmitted packets from SoC.
    You need to register an ALE entry to forward the packets on any ports.

    You can check by dumping ALE entries, whether destination MAC address of transmitted packet from SoC registered in ALE or not?

    Also, note that tomorrow is a Holiday in TI India. Kindly expect delay in response.

    Hello,


    I thought for ALE related drops there is another specific field in the stats.

    Also ALE bypass mode is active.

    The Frame to be transmitted has the port on which it should be transmitted set.

    You need to set the port number intended to transfer the packet in info word data for directed packets. 

    If not packet will be dropped.
