Correct. If you want the official terminology, applications that send GET and GETNEXT requests are called "command generators". A full NMS is an example of such a command generator. > 2) SNMP agent runs on a device/server and responds to snmpget and > snmpget next etc. Correct. The official terminology here is a "command responder" > It also issues traps to NMS. The official terminology talks about "notification generators and receivers". An SNMP agent is typically both a command responder, and a notification generator. A notification receiver may be a full NMS, or a specialised trap-handling application (such as 'snmptrapd') > Net-SNMP is an agent. No. Net-SNMP is a suite of software, comprising an SNMP library, an SNMP agent (snmpd), a notification receiver (snmptrapd), and a suite of simple command generators (snmpget, etc). The Net-SNMP project does not claim to include a full NMS application - that's outside the scope of what we're trying to provide. We just provide some simple low-level command-line tools that can be used to query SNMP agents to retrieve information. Any more comprehensive or coordinated, we leave to other software. > Q) If Net-SNMP is an agent why it has snmpget, snmpwalk etc. > which are NMS functions?
