Introduction to SNMP
SNMP (Simple Network Management Protocol) is a standard network management
protocol widely used in computer network management. SNMP is an evolving protocol.
SNMP v1 [RFC1157] is the first version of SNMP which is adapted by vast numbers of
manufacturers for its simplicity and easy implementation; SNMP v2c is an enhanced
version of SNMP v1, which supports layered network management; SNMP v3 strengthens
the security by adding USM (User-based Security Mode) and VACM (View-based Access
Control Model).
SNMP protocol provides a simple way of exchange network management information
between two points in the network. SNMP employs a polling mechanism of message
query, and transmits messages through UDP (a connectionless transport layer protocol).
Therefore it is well supported by the existing computer networks.
SNMP protocol employs a station-agent mode. There are two parts in this structure:
