Hi, could it be that the printer send the snmp pakets as broadcasts and occupy in that way switch processing load.
Use Netflow tools like scrutinizer to see how the packets flows (Source IP / destination IP / Data amount). Maybe a port mirror of a printer which is causing that traffic will help to understand how traffic flow. At N7 HW you can use logging of an ACL or Policy to see what SNMP Traffic will occupy switch resources.

Unfortunately there was an error in the driver-configuration, resulting in an huge mass of snmp-packets between the printers and the workstations. The problem: although these paket-streams are only transported (not to be interpreted) by our switches (C2, C5, N7), the cpu-load of the stacks/modules goes over the top (>95%) and the SNMP-processes use >80% of it. My question is: why??? The snmp-datastream is big, but not the biggest one, not by a long shot.
