SNMP basic background
Simple Network Management Protocol (SNMP) is an application layer protocol.
It makes the management information between network devices exchange easier. It is
part of the TCP / IP protocol group. SNMP enables the end-users to manage network
performance, find and solve network problems, and arrange for future network
upgrades.
Management Information Base (MIB) is the organized hierarchical information
set. Use SNMP to visit these MIB. They are composed of manageable information,
and identified by the object identifier.
