Multicast, Network Bridge, Server 2019 and I350-T2

[Tom_T]

Hi

I have a Intel Ethernet Server Adapter I350-T2 and a Server 2019 install.

When I enable a network bridge it seems that Multicast is stopped. How do I make sure that multicast packages move between the two ports?

Hi

thanks for answering.

No, no screenshot.

Yes, PCIe I350-T2 in a Dell Precision 3640 with i9-10900K and Nvidia P2200

I use latest Intel drivers, showing as 12.18.13.0

Bridge is set 192.168.20.140. I can ping the "downstream" device connected to #2 NIC which is 192.168.20.138. And I can ping all other IPs in the network. 

I can remote desktop into both devices 192.168.20.140 and x.138

Firewall is turned off. Both are running Server 2019.

When I connect x.138 and multicast app on x.140 discovers x.138. But when plugged into bridge x.138 is not detected.

Thanks

Tom

Sorry, last two sentences unclear. When I connect x.138 with a switch, all work, if I connect in #2 port, then only ping works but not multicast detection...

Hello Tom_T,

Thank you for the quick reply. Upon initial inspection, your card does not have the YottaMark* and BradyID* Stickers. Please check the link below for more details about those stickers.

Upon checking the markings, as per the part number. Your network card is an OEM unit from Dell. Dell may have altered the features of this card so for further assistance, kindly contact Dell and coordinate the issue with them.

If you have questions, please let us know. In case we do not hear from you, we will make a follow up after 3 workings days. Thank you.

Thanks Michael, I was not aware that you still monitor this ticket. Appreciated.

I will follow up with Dell. While I did not buy from them, the card runs in a Dell Workstation still under warranty. So they might be able to help.

Thanks again
