Simple Network
Management Protocol
(SNMP)
The Raven is can be configured as an SNMP agent and supports SNMPv2c and
SNMPv3.
SNMP Overview
The Simple Network Management Protocol (SNMP) was designed to allow remote
management and monitoring of a variety of devices from a central location. The
SNMP management system is generally composed of agents (such as your Raven, a
router, a UPS, a web server, a file server, or other computer equipment) and a Net-
work Management Station (NMS) which monitors all the agents on a specific net-
work. Using the management information base (MIB), an NMS can include
reporting, network topology mapping, tools to allow traffic monitoring and trend
analysis, and device monitoring.
Authentication ensures SNMP messages coming from the agent, such as the Raven
have not been modified and the agent may not be queried by unauthorized users.
SNMPv3 uses a User-Based Security Model (USM) to authenticate and, if desired,
message encryption. USM uses a user name and password specific to each device.
