Download Wireshark with RoCEv2 Support

Version 3

    Attached is a preliminary version of Wireshark with InfiniBand support for RoCEv2. In time, it will be added to the Wireshark upstream.

     

    After the installation, click Edit -> Preferences -> Protocols -> InfiniBand, and perform the following adjustments:

    1. Type the UDP port as 4791 (RoCEv2 default).

    2. Make sure the two check boxes on top are cleared.

     

    Example:

    Following the steps above, you can open any *.pcapng file to see the InfiniBand parsing of the RoCE traffic.

     

    Here is a parsing example of the BTH header of a CNP packet, OpCode 0x81 (RoCEv2 Congestion Management Ack):
