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.
