Well last week I upgraded the Switches from a customer to the latest release.
MS225-24P from MS 15.21.1 to MS 17.2.1.1
The setup:
I have a main site with about 15 branches. On all sites I have MS225 and also AP's.
After the upgrade users have problems with printing. The print server is in the main site. Each site has some printers, different vendors.
The problem is that some printers (differnet models) do not respond any more. For failing printers some of them the ports on the switch will suddenly disconnect, but not all of them. In the event of failing the printer also do not respond to ping, even the dashboar shows still connected.
For the ports which are disconnected, I see this in the event log. but no reason. for the ports staying up, but still problems with the printers...no event log.
Recycle or disabling/enabling the port solves the problem for an undefinded time.
did someone experience such problems with printers with the current release MS 17.2.1.1?
For me it looks that there are some problems with the negogiation between the switch port and the printer.
I will rollback two sites this evening to see if the problems dissapear with the old release again.
Any idea or help is appreachiated.
