I have faced this issue with every SG300 I have worked on. I can only imagine this to be a bug.
It is mostly with printers (HP, Brother, Zebra). I connect 3 devices to the switch. A PC and a printer and the uplink. I am able to browse and ping the printer yet nothing in the MAC table for that interface. PC MAC is listed correctly.
Aging set to 600 seconds. I have seen it pop up briefly in the table in rare cases but next time I look it is gone again. The switch knows the MAC as IP traffic flows correctly but it will not report it reliably.
Would be great to find a solution.

Hi Cisco Team,
We need help too about that bug ! Same issue here with WS-C2960+24PC-L 15.0(2)SE9

Is it a functionnality to activate or deactivage in the printers ethernet cards ?
Thank you Cisco to help us in this post

I had a similar issue when I was working with the Catalyst 4948 this summer for a customer. The way I got the mac address-table to populate was to ping the device from the switch. I just threw together a quick text file and had to run through the entire subnet.
