Yes, I've seen something similar - the switch reports that it's not forwarding traffic, but if you send a job to the device it does get printed, and you get a reply if you ping the device by IP address (although the first couple of packets are lost before you get a response).   I swapped both printers and switch ports and the behaviour follows the specific device, but I did notice that it only happens when Xerox MFP devices are connected (HP/Canon devices are ok)   I suspect that it's the copier going into Sleep/power saving mode and the switch stops forwarding traffic because it's not receiving the expected response from the printer.   I tweaked the option to enter power saving mode after 1 hour (from memory I think the default was 15 minutes) but it's still happening, and I gave up researching after I couldn't find anything to confirm the above on Meraki/Xerox/google, etc   Snip from this morning:                 ...

Thanks @Brash - I've seen that before but I'm not convinced it provides the detail I'm after, but I'll have another look.   I was hoping for something that showed when the port status last changed so I could compare that with the switch boot time, so looks like I'll need a 3rd party monitoring tool. ...

Thanks both for confirming.  I was hoping to achieve this without a third part solution, but looks like that's not an option.   Rather annoyingly we had Solarwinds for monitoring our previous network environment and I could configured that to give exactly what I want, but we are in the process of phasing out Solarwinds since we've migrated to Meraki as I can't justify the additional costs now.   I'll also have a look at the options mentioned ...
