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
information using software such as HP OpenView. Access to the onboard agent
from clients using SNMP v1 and v2c is controlled by community strings. To
communicate with the switch, the management station must first submit a valid
community string for authentication.
