Thanks @LaurentMa!

 

Yeah I actually just checked last night and saw the new firmware! You beat me to replying in this thread that the new version was released. 🙂

 

Thanks again, I will give it a try in the next few days!

@LaurentMa, did you have an ETA on the new firmware for the GS752TS that resolves this issue?

 

Thanks 🙂

OK we have the internal patch for GS728TS/GS752TS/GS728TPS/GS752TPS but the code is being merged with another urgent fix for imminent maintenance release. The ETA will be in one week from now for web publishing.

What about fixed firmware for GSM7248v2 and M7100-24X switches?

@LaurentMa Thanks! I have been running the latest firmware with 4 of the new Ubiquiti APs now for about 2 weeks. Working great now!

Hi elderone

 

Technical validation and QA took longer for denser products like Fully Managed Switches and we expect to see final maintenance releases published before the end of this week. For now there are in e-room accessible by our Technical Support teams, so please don't hesitate to contact them and request the new firmware in advance:

 

Fully Managed Switches:

  • M4100 like your GSM7248v2: 10.0.2.25
  • M5300, M6100, M7100 like your XSM7224 : 11.0.0.29

Regards,

Re: STP Leak using Broadcast packet 01:80:c2:00:00:1c

We have hundreds of Netgear switches and hundreds of UniFi APs under management at various sites.  We're only having this problem with one GSM7224 (not listed in the pulldown above).  It is not stacked. We have another identical switch in another building at this site and it is not exhibiting the issue.  I found that the good one was running 8.0.1.26 firmware while the broken on was at 8.0.1.36.  Downgrading to the older firmware on that switch did not resolve the issue however.  We've implemented the temp fix as recommended here and are wating for something permanent.

Hi 

 

Sorry for this issue. Is your GSM7224 a M4100 GSM7224v2h2 (M4100-26G) for which we are releasing 10.0.2.25?

Re: STP Leak using Broadcast packet 01:80:c2:00:00:1c

Nope. This is an old-fashioned GSM7224V2 running 8.0.1.26.  I had downgraded from 8.0.1.36 because we have another identical switch at this location that was not impacted by the UniFi upgrade.  That didn't resolve the problem and I have no idea why one switch is fine and the other is problematic.

@LarryV and to others, 

 

Since a firmware fix is not yet available, the MAC ACL workaround can be used as described on the article below:

 

Adding a MAC ACL on Fully and Smart Managed switches to prevent STP leak of multicast packet from 3r...

Re: STP Leak using Broadcast packet 01:80:c2:00:00:1c

I can confirm the latest firmware has fixed the leaking broadcast packet storm.

I have two GS716Tv3 and a GS710TP all attached in LAG loops for redundancy.

GS716Tv3 code = v6.3.1.19

GS710TP code = v5.4.2.30

I have 4 Vlans spanning the Lags.

 

I have updated all the Ubiquity AP's to the latest code.

Removed all MAC acls.

 

All is working as expected, APs broadcast this packet when a client roams.

Only one packet now per roaming event.

 

Excellent work Netgear.  Thank you for the fix and for helping the community.

 

-Rich
