Why doesn't the SLM2024 Smart Switch 10/100/1000 support 10M?
Since a couple of weeks I have installed 5 SLM2024 Gig Smart Switches. Now we have a new Time Attendance System that tries to communicate to the Cisco with 10M. The Cisco identifies it correctly but will not parse any info to the Device. Why is that?
Test it with a D-Link 10/100 Switch -> OK
Test with a Cisco 10/100 Switch -> OK
Test with noname 10/100/1000 Switch -> OK
Test with SLM2024 -> Failed.
I would love for someone to explain this to me. What does the Cisco do? I would gather that if a Switch is 10/100/1000 it can communicate over anyone.

I would definitely expect to be receiving broadcast packets, maybe ARP packets from the time attendance advice.
Yep that is a problem.
But, why are you not receiving broadcast packets on the port that is connected to the time attendance device.hmm that my question that I am mulling in the back of my mind. Your switch port statistics showed an issue.
A wireshark or packet trace would be most useful , so mirroring the time attendance switch port to your PC's switch port would be useful. This would allow us to see what is coming in and out of that switch port.
Pretty easy to setup on this managed switch, see my screen capture below as an example.
Wireshark is a wonderful freeware 'sniffer' software that would allow us to see the ethernet frames coming in and out of the switch port in question.
