print management find mac address of a printer

I’m thinking the fix is just going to be turning off all possible power save settings, and potentially keeping the persistent pings going which may make the bean counters unhappy.Įdit: fix that I’ve implemented: added printers to monitoring system, and either of these two commands: aaa port-access Mac-based logoff-period 1-9999999 (1 second to 115 days) or aaa port-access mac-based Mac-pin (disable log off period entirely and pins MAC so they survive port flaps and reboots). Setup NTP with low update intervals, switched to DHCP, and many others settings have been changed to try and keep the NICs on these damn things alive too.Īnybody else run into similar issues and have any tips, or can at least sympathize with me? I’ve also setup a persistent ping to the printers to try and keep them alive, but it feels stupid and hacky. Ive set the control direction for 802.1x to “in” on all printer ports but am still having intermittent issues. When entering power saver mode the printers flap the port and delete their MAC from the port.įor 802.1x I suspect power save mode is to blame as well.

This is even the case for MAB printers.įor MAB at least, I see the issue. The problem is that printers, even if they “fully support 802.1x,” fall off the network and the end users need to manually power cycle them to get them back up. We’re doing EAP-TLS for user workstations and PEAP for devices like printers. We have a wired 802.1x setup with NPS dolling out dynamic VLANs, and printers have been the bane of my existence since setting this up.
