    TP-SG105E V3 (Multicast) need help

    Model :

    Hardware Version :

    Firmware Version :

    ISP : [/COLOR]

    Hello,

    i have a problem i need Multicast feature for any operation mode of inverter connection of an photovoltaic system

    Now i use a TP-SG105E v3 which refer in Manuel and Operation Config "IGMP Snooping" Multicast option.
    If i connect now the PV system to the Swich it does now get any connection trough the ethernet cable to an TP-Link LTE Router which are made the connection to the internet.

    But if i connect PV inverters (via Cat7 cable) directly to the router it will be identify and router can find the connected devices.

    What i have to modify at the switch that it works too ? Or which other version i need if it does not work?

    IGMP are enabled

    Hope anyone can help.

    Thanks

    best regards,

    Harald

    Hi dude, when you use the SG105E, will the multicast table show the details about IP addreee, VLAN ID and ports?

    Hi,

    nothing looks failure thats why i am so confused in this case. Okay i use Powerline between switch and endpoint (TP Link LTE Router) but
    currently found solution that i change units from DHCP IP to Static IP and it works at the moment.

    I think Switch does not handle DHCP IPs correct if i route this over a powerline system.

    Is there any firmware upgrade available for the switch ? I do not found new flashROM

    regards,

    Harald

    Sorry, Not much clear about your topology. Is the PV inverter is a solar PV inverter? The problem is the PV Inverters can't get IP when it use DHCP?
    Why will it need IGMP snooping?
