Hello [NAME] Paul,   I've consulted on one of the switch support colleague, to disable SNMP trap, you can run the command #no snmp-server enable traps ecmp. In order for you to enable SNMP server, you will need to configure snmp-server in your server and configured it. Then based snmp-server configured on system, you have to configure snmp-server community, view, groups etc on switch.   Here the switch user guide for reference: [URL] page 1532 onwards.
We have 2 S4048ON switch connected in a stack. How to disable SNMP trap and enable SNMP server for the stack. What are the configuration to be done to enable SNMP. Thank you for your support   Paul
