X440 and Netsight Nac The session is no longer active due to: Admin-Reset.

Hello all

i have the following Problem with one Device in our Network
It is an CAB Label Printer connected on an X440 with Netsight
After 10 Minutes the following message is in the Netsight Nac manager

The session is no longer active due to: Admin-Reset.

If the message appear in the NAC the Device is no longer reachable
only Force Reauth and Power off the Device brings it back

Is anbody here that have an idea was it is

regards
Oliver

Might be a problem with the printers powersave option - try to change it to a higher value and see whether that increases the time till it doesn't work.

Do you poll the printer via Netsight - could be a "workaround" - if you poll it all the time it might also solves the problem.

Hello Oscar and Ronald
there is no entry in the switch log

Mac authentication is used

Our X450 switches show the same message in the NAC but the CAB Label Printers on these switches are reachable after the message
The Status switch from disconnected to accept if we print or ping the Device

What kind of authentication is used ?

Maybe the switch clears its fdb entry and this causes the admin reset ? You should see that in the switch log.
