This chapter describes how to create new Simple Network Management Protocol (SNMP) version 3 (v3) users to provide secure access to the Oracle Solaris SNMP agent. For SNMP version 1 (v1) and version 2 (v2c), the access control mechanism is the community string, which defines the relationship between an SNMP server and its clients. This string controls the client access to the server similar to a password controlling a user's access to a system.
