MAC authentication printers sleep mode

[lien_monden]

Hi,

I've set up RADIUS/MAC authentication on Ruckus ICX7150 switches on a customers site. Everything works fine except for label printers that go in sleeping mode. When the printer goes in sleeping mode, the switch port goes down and the authentication session is cleared. Then I see the port comes up again, but the printer is not trying to authenticate anymore unless you restart the device.

Is there some option to keep the authentication session valid even when the printer goes in sleeping mode? Maybe some sort of mac-pinning that locks the device on the port?

thanks!
