M6100 Link Down Events
We have a switch with 40 'link down' events listed in the log for physical ports 1/0/43 & 2/0/43 but none listed for the lag that they're associated with. There are a mere 38 broadcasts listed for the physical ports mentioned above but over 10 million for the associated lag. Does anyone know or care to speculate as to why this is happening?

Hi Electrical,
We have a switch with 40 'link down' events listed in the log for physical ports 1/0/43 & 2/0/43 but none listed for the lag that they're associated with.
What devices are connected to ports 1/0/43 & 2/0/43? It would be best if you post an image of your detailed network setup.
What is the current firmware version of your M6100 switch?
In order to analyze the logs from the M6100 switch, I suggest you to open a chat or online support ticket with NETGEAR Support at anytime.

The firmware is 11.0.0.31 for both blades in the M6100 and they're configured in a LAG on ports 1/0/43 & 2/0/43 to an EdgeRouter ER-8-XG running 2.0.3. Both devices are using LACP and aren't experiencing any problems aside from the aforementioned. I'm not sure it's even a problem...more of a curiosity at this time.

I inquired your concern to the higher tier of NETGEAR Support and just got a feedback. As per the higher tier of NETGEAR Support, if the amount of broadcast traffic associated with the LAG is less or about 1% of the total traffic flowing on the LAG, everything should be fine. For ports 1/0/43 and 2/0/43 going down, further investigation is needed. The tech support file of your M6100 switch is needed to be analyzed.
To get the tech support file:
1. Login to the web GUI of your M6100 switch then go to Maintenance > Upload / Export > HTTP File Upload / HTTP File Export.
2. In the File Type drop-down menu, choose Tech Support and click Apply.
3. When prompted, save the tech support file to your computer.
For the logs and tech support file to be analyzed, kindly open a chat or online support ticket with NETGEAR Support at anytime. State your concern and be sure to attach the logs and the tech support file.
