Intel x710 and Multicast traffic

[furfix]

Hi All, hope somebody can help me a little with this.

I have a box where I'm running OPNSense baremetal that comes with i226 nic and x710 nic. Since my ISP handoff is fiber, I'm using the x710 one, but after long hours, I came to the conclusion that Multicast traffic is not working with the x710. Same config, but using the i226 for the LAN works fine. I've also installed a Mellanox card on the box to be sure that the Intel x710 is the problem, and indeed...with the Mellanox Multicast is working fine.

I would really appreciate if somebody can help me to narrow the issue, because I don't know what else to do to keep troubleshooting the problem.

Is it maybe possible to update the Intel Drivers? I read it is not recommended to install drivers to avoid issues with OPNsense.

Code: [Select]

<5>ixl0: Link is up, 1 Gbps Full Duplex, Requested FEC: None, Negotiated FEC: None, Autoneg: True, Flow Control: None
<6>ixl0: link state changed to UP

<5>ixl1: Link is up, 1 Gbps Full Duplex, Requested FEC: None, Negotiated FEC: None, Autoneg: True, Flow Control: None
<6>ixl1: link state changed to UP

I'm not sure if it has something to do with this, but also i see a LOT of these msgs:

Code: [Select]

<6>ixl0: Disabled multicast promiscuous mode
<6>ixl1: Disabled multicast promiscuous mode
I've updated also the Firmware of the x710, but no changes:

Any idea, will be much appreciated!

Check if this kernel fixes it for you.

Code: [Select]

opnsense-update -zkr 24.7_11 && opnsense-shell reboot

[franco]

"_11" was a bit of a hit and miss and I have removed it now. I can recommend "_10" as that is definitely a patch set that is part of 24.7.1 and has IGMP specific fixes:

# opnsense-update -zkr 24.7_10 && opnsense-shell reboot


Cheers,

Hi! Just tried, but I get this error:

Code: [Select]

Fetching kernel-24.7_11-amd64.txz: ..[fetch: https://pkg.opnsense.org/FreeBSD:14:amd64/snapshots/sets/kernel-24.7_11-amd64.txz.sig: Not Found] failed, no signature found


[franco]

Why, yes.

[furfix]

Sorry, replied at the same time. Ive tried 24.7_10 yesterday, but no luck. The issue remains in my case (and for the records, just with the x710 NIC). Both i226 and Mellanox were working fine, even with the current 24.7 kernel, but somehow the x710 doesn't like it.

[furfix]

Why, yes.

I tried again the _10 for the sake of trying to solve it, but still IGMP/Multicast seems to no be working for this card. If you think I can troubleshoot it somehow or share more logs, or anything you  may need, just let me know.

[furfix]

@franco, is there anything I can do to help? Should I open an issue in Github with this info? What other information would be helpful?

Thanks in advance!!

[franco]

Did this start with 24.7 or was this always going on? I'm asking to see if I should check driver commits or dig somewhere else.


Cheers,
Franco

@franco I've sent you via DM the outcome of the commands Intel asked to run. If I can help with anything else, please do not hesitate to let me know.

[franco]

I'm currently too busy until 24.7.2 is out, but I will try to follow up on it later this week. Sorry.
