SNMP OID: Full Insight
SNMP uses OIDs to uniquely identify pieces of data (like CPU usage, interface status, etc.). Standard OIDs (defined by IETF) are common across all devices , e.g.: 1.3.6.1.2.1.1.1.0 → sysDescr (system description) 1.3.6.1.2.1.2.2.1.10 → ifInOctets (interface input bytes) Vendor-specific OIDs: For example: Vendor Enterprise OID Base Example Cisco 1.3.6.1.4.1.9 1.3.6.1.4.1.9.1.516 (Cisco 2960 model) Juniper 1.3.6.1.4.1.2636 Juniper-specific OIDs HP 1.3.6.1.4.1.11 HP printer/router OIDs Fortinet 1.3.6.1.4.1.12356 FortiGate device OIDs Part 1: Standard SNMP OID – .1.3.6.1.2.1.1.1.0 This is used for system description , and it works on all SNMP-supported devices (routers, switches, servers, etc.). Let’s break this path: 🔹 .1 → iso International Organization for Standardization This is the root of the SNMP OID tree. Every OID begins from here. 🔹 .3 → org Organization This level is used for organizations that are registered under ISO. 🔹 .6 → dod Depart...
