SNMP

SNMP Overview

Simple Network Management Protocol (SNMP) is a protocol for managing and monitoring network devices efficiently. EdgeOS supports SNMP read functionality, allowing network administrators to use SNMP queries to extract device information and monitor network performance.

This guide briefly describes the SNMP functionality and explains how to utilize the supported Management Information Base (MIB) tables for effective network management.

Supported SNMP and MIBs

SNMP Versions: EdgeOS supports SNMPv2c

MIBs: EdgeOS supports standard system and interface MIBs. These MIBs define a set of variables that EdgeOS exposes for SNMP operations, such as querying system information or interface metrics.

Configuring SNMP on EdgeOS

Enable SNMP: In EdgeOS, access the SNMP settings by navigating to Menu → Configuration → General Settings → SNMP

Enable SNMP by toggling the option to Enable.

Set Community Strings: Define Community strings for authentication. The Community string acts as the password that allows read access to the device's MIB information.

MIB Object Identifier (OID) Tables

No specific MIB file is provided for download, as the standard system interface MIB is supported. The following table lists specific identifiers available from the EdgeOS system.

System MIB OID	Details
1.3.6.1.2.1.1.1 - sysDescr	System Type
1.3.6.1.2.1.1.2 - sysObjectID	1.3.6.1.2.1.1
1.3.6.1.2.1.1.3 - sysUpTime	System uptime
1.3.6.1.2.1.1.4 - sysContact	Kognitive NOC Contact
1.3.6.1.2.1.1.5 - sysName	SiteName
1.3.6.1.2.1.1.6 - sysLocation	Device Name (if configured)
1.3.6.1.2.1.1.7 - sysServices	Device Serial Number

The following table lists the specific interfaces available:

ifMIB OID	Details
1.3.6.1.2.1.2.2.1.1 - ifIndex	All the configured/available WAN/LAN/Management interfaces are listed Index 1x - LAN Index 3x - WAN and WAN sub interfaces Index 5x - Management Interfaces
