What is SNMP ?
-- Simple Network Management Protocol (SNMP) is an application–layer protocol defined by the Internet Architecture Board (IAB) in RFC1157 for exchanging management information between network devices.
-- SNMP is one of the widely accepted protocols to manage and monitor network elements.
-- It is used for collecting information from, and configuring, network devices, such as servers, printers, hubs, switches, and routers on an Internet Protocol (IP) network.
-- You can monitor network devices such as servers, workstations, printers, routers, bridges, and hubs, as well as services such as Dynamic Host Configuration Protocol (DHCP) or Windows Internet Name Service (WINS).
-- Use SNMP management software to monitor any network device on which you install SNMP agent software
-- Using SNMP, you can monitor network performance, audit network usage, detect network faults or inappropriate access, and in some cases configure remote devices.
-- SNMP commands to read and write data in each device MIB. 'Get' commands typically retrieve data values, while 'Set' commands typically initiate some action on the device.
-- For example, a system reboot script is often implemented in management software by defining a particular MIB attribute and issuing an SNMP Set from the manager software that writes a "reboot" value into that attribute.

SNMP consists of
- SNMP Manager
- Managed devices
- SNMP agent
- Management Information Database Otherwise called as Management Information Base (MIB)
