Simple Network Management Protocol
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 the format of the MIB specifications and the protocol used to access this
information over the network.
The switch includes an onboard agent that supports SNMP versions 1, 2c, and 3.
This agent continuously monitors the status of the switch hardware, as well as the
traffic passing through its ports. A network management station can access this
