sysObjectID
Module: SNMPv2-MIB
OID (symbolic): SNMPv2-MIB::sysObjectID
OID (numeric): 1.3.6.1.2.1.1.2
Node type: OBJECT-TYPE
Type: OBJECT IDENTIFIER
Access: read-only
Description: The vendor's authoritative identification of the network management subsystem contained in the entity. This value is allocated within the SMI enterprises subtree (1.3.6.1.4.1) and provides an easy and unambiguous means for determining `what kind of box' is being managed. For example, if vendor `Flintstones, Inc.' was assigned the subtree 1.3.6.1.4.1.424242, it could assign the identifier 1.3.6.1.4.1.424242.1.1 to its `Fred Router'.
What is sysObjectID?
This is a dotted-number identifier (like 1.3.6.1.4.1.9.2.1.58) that uniquely identifies the vendor and device model. Network engineers use it to programmatically determine exactly what device is being managed without parsing text descriptions. For example, 1.3.6.1.4.1.9.2.1.58 tells management software 'this is a Cisco router,' while 1.3.6.1.4.1.311.1.1.3 identifies a Windows system.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.1.2 snmpwalk -v2c -c public <target> SNMPv2-MIB::sysObjectID
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.1.2.1 snmpget -v2c -c public <target> SNMPv2-MIB::sysObjectID.1
Example output:
SNMPv2-MIB::sysObjectID.0 = OID: NET-SNMP-MIB::netSnmpAgentOIDs.10
