IGMP General Queries arriving to switch but not making it to host connected to 1930 version 3.0.0

  • 1.  IGMP General Queries arriving to switch but not making it to host connected to 1930 version 3.0.0

    Posted 12-27-2024 07:29 AM

    I've taken a deep dive into IGMP.

    IGMP General Queries are being sent by core switch (confirmed via wireshark) and are being received by the 1930 on the tagged port (also confirmed via wireshark)

    However, the host never receives the IGMP General Query message.

    The only "workaround" I have found is to statically tell the 1930 the port where the mcast router is attached to.

    My understanding is that the 1930 should be able to dynamically do this, without having to statically do this.

    Any ideas what could be causing this?
