Net-SNMP v3: Brief Overview

Simple Network Management Protocol (SNMP) is an Internet-standard Application Layer protocol used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. The SNMP agent receives requests on UDP port 161 and the manager receives notifications (Traps and InformRequests) on port 162 but when SNMP is used with Transport Layer Security (TLS) or Datagram Transport Layer Security (DTLS) requests are received on port 10161 and traps are sent to port 10162.
