    Hello,

    At a customer we are using 3 stacks of 3 x670v-48 switches.
    These are configured native stacking.
    The multicast used is PIM Sparse mode.

    In the log file I keep seeing the following message:

    Heelo Erwin,

    Kindly add another article for this topic.

    Hello,

    Thanks for the information.
    In the first article you provide instructions to configure an IGMP snooping filter per VLAN. The example given in the article is that a certain Hardware Limitation of a table has been reached, but that is not the case in our environment.

    In fact, the maximum multicast adresses is around 4000 on a x670v-48 switch. Is this still a step you recommend to follow?

    To me, the information shown when using the command
    show iproute reserved-entries statistics [/code]displays expected data (around 370 multicast adresses).

    Is it possible that this has something to do with the firmware we use?
    Firmware version 15.4.1.3 [/code]Best regards,
    Erwin

    Can you give the output of the "show iproute reserved-entries statistics" CLI command?

    Hi Erwin,

    i recommend you to bring this switch to a recent firmware to exclude all the old bugs ...

    Here the vendor recommendation matrix:
