Printer MAC Authentication issue after enabling Port Access on the Switch
Printer MAC Authentication issue after enabling Port Access on the Switch
Monday - last edited Monday
I have added the printer MAC Address in Endpoints. Once Port Access is enabled on that switch port the printer goes offline. We have it setup this way for all other printers and they don't have any issues. If I turn off Port config they printer comes back online. It's and HP LaserJet M553. Any suggestions would be appreciated.
Thank you,

Is this happening just for this printer?
Some printers have the habit to go into sleep mode after a period of inactivity, to save power. In such a state, the device only responds to arp requests (and other direct traffic) and will wake up again. If you enable mac-authentication on the port during such a sleep period, it will appear that the device drops off until it generates traffic again.
If you don't see an authentication request after enabling mac-authentication on the port, try disconnecting the cable (or disable port) and reconnect (or enable); as last resort reboot printer and you should see MAC authentication happen.
As when printers go to sleep, the authentication might time out and get disconnected, in the ArubaOS switches version 16.05 a feature called MAC Pinning was introduced to solve this issue by keeping the authentication active till the device starts sending traffic again.

Hi,
Try to change the logoff timer, it worked for me in a few installations.
The probleme happens with printers, which go asleep.
You could set the time for mac and 802.1x
aaa port-access authenticator 1-48 logoff-period 430000
aaa port-access mac-based 1-48 logoff-period 3000000
