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.
