Simple Network Management Protocol
SNMP is a communication protocol designed specifically for managing devices on a
network. Equipment commonly managed with SNMP includes switches, routers and
host computers. SNMP is typically used to configure these devices for proper
operation in a network environment, as well as to monitor them to evaluate
performance or detect potential problems.
Managed devices supporting SNMP contain software, which runs locally on the
device and is referred to as an agent. A defined set of variables, known as managed
objects, is maintained by the SNMP agent and used to manage the device. These
objects are defined in a Management Information Base (MIB) that provides a
standard presentation of the information controlled by the agent. SNMP defines both
