enabling all of the traps could have a potential impact on performance. Every trap produced will take resources to process. If there are a large amount of traps that occur at the same time it could potentially degrade performance while those traps are processed.  By default, Authentication, Link Up/Down, Multiple Users and Spanning Tree flags are enabled. I would recommend enabling specific traps that you need to monitor on-top of the the default.
If i will enable all the SNMP traps instead of enabling some specific traps. Will there be any effect on the device performance or network performance? What is recommended either we have to enable specific traps or all the traps of SNMP?   Regards,Mukesh KumarNetwork EngineerSpooster IT Services
