Summary
SNMP (Simple Network Management Protocol) - is widely used in networking management for networking monitoring. SNMP uses MIB (Management Information Base) to organize management data in the form of variables, which describe the system configuration and status.
This chapter is a guide on configuring SNMP package to establish communication between devices.
Preconditions
RUT9xx
To setup SNMP first make sure that SNMP package is installed, more information here RUT955 Packages and RUT950 Packages.
OID codes
OID code (Object identifier code) - is an address used to identify devices and their status.
OID code is represented by the numbers in the boxes starting from "root".
Number | Label | Explanation |
---|---|---|
1 | iso | ISO is the group that established the OID standard |
3 | org | An organization will be specified next |
6 | dod | The US Department of Defense (established the early internet) |
1 | internet | Communication will be via Internet/network |
4 | private | This is a device manufactured by a private entity |
1 | enterprise | The device manufacturer is classified as an enterprise |
48690 | Teltonika | Teltonika enterprise number |
Field | Number | Explanation |
---|---|---|
static | 1 | Static router information (Router name, Modem Imei, Modem Modle etc.) |
gsm | 2 | Sim card information (Sim State, Operator, Mobile IP etc.) |
hotspot | 3 | Hotspot information (Hotspot ip, users etc.) |
Trap | 4 | Trap messages (Information sent through trap messages) |
rut9x5 | 5 | Input/Output information |
gps | 6 | GPS information (Latitude, accuracy etc.) |
ethernet | 7 | Information about router ports |
MIB File
MIB File can be used with MIB browsers for easier access to router configuration and status information variables. Download the MIB file and upload/load it in MIB browser.
Generating OID code from MIB File
MIB File contains all OID codes.
Line containing numbers needed for OID code can be identified by this marking "::=".
All that is left, is to add the numbers together. Example from given MIB File: 1.3.6.1.4.1.48690.1.1.0.
Important note: Do not forget to add .0 at the end of the generated OID code.
SNMP Configuration
To configure SNMP, first enable SNMP service, leave or change port you can leave everything else as it is.
