Management Protocol

• SNMP Configuration
• SNMP MIB Definition	The Simple Network Management Protocol (SNMP) was
Sample
	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 Network Management Station
	(NMS) which monitors all the agents on a specific network.
	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 or supported, message encryption. USM uses a user
	name and password specific to each device.
	The Raven can be configured as an SNMP agent and supports
	SNMPv2c and SNMPv3.

Management Information Base (MIB)

The management information base (MIB) is a type of database used to compile the information from the various SNMP agents. Reports from various agents, such as the Raven, are sent as data in form designed to be parsed by the NMS into its MIB. The data is hierarchical with entries addressed through object identifiers.

SNMP Traps

SNMP traps are alerts that can be sent from the managed device to the Network Management Station when an event happens. Your Raven is capable of sending the linkUp trap when the network connection becomes available.
