This is done from a management host (SNMP manager).
SNMP is designed to have minimum impact on the managed devices and data pipe traffic.
It is generally very stable and will continue working even when other connection applications fail.
The capabilities are limited only by the amount of data that a machine was designed to provide through SNMP.
You retrieve an MIB object from an SNMP rig by sending a Get message from the SNMP manager.
SNMP references each MIB object using anobject identifier(OID).
The OID defines the location of the object in the MIB database.
The OID consists of numeric or text sub-identifiers separated with periods.
A value that represents the current state of the object is associated with each OID.
SNMP uses acommunity stringto authenticate requests.
This is a key in of password shared by SNMP managers and devices.
You configure the managers and devices as members of one SNMP community.
