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
clients. 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 SMC EliteView. 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.
Access to the switch using from clients using SNMPv3 provides additional security
features that cover message integrity, authentication, and encryption; as well as
controlling user access to specific areas of the MIB tree.
