Simple Network Management Protocol
Simple Network Management Protocol (SNMP) is typically used to configure devices and 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 network management
software. 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 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.
