How to identify different vendors ' devices through the OID of SNMP

As we all know, SNMP is commonly used as a common network protocol in system monitoring, so how to use SNMP to identify different manufacturers of equipment?

In fact, in the OID tree of SNMP, a node is specifically used to identify the different vendors, which are:

ISO (1) identified-organization (3) DoD (6) Internet (1) Private (4) Enterprise (1)

Sub-nodes below this node can be applied by each vendor or organization, and then how to organize the nodes to be handled by each vendor or organization itself, for private OIDs.

For example, for Cisco devices, whose child nodes are 9, we can use snmpwalk to find . 1.3.6.1.4.1.9 this OID:

[Email protected] ~]# snmpwalk-v 2c-c Public192.168.1.1.1.3.6.1.4.1.9SNMPv2-smi::enterprises.9.2.1.1.0= STRING:"System Bootstrap, Version12.4(13r) T11, RELEASE Software (FC1) Technical support:http://Www.cisco.com/techsupportCopyright (c) theby Cisco Systems, Inc."Snmpv2-smi::enterprises.9.2.1.2.0= STRING:"power-on"SNMPv2-smi::enterprises.9.2.1.3.0= STRING:"2821"SNMPv2-smi::enterprises.9.2.1.4.0= STRING:"yourdomain.com"SNMPv2-smi::enterprises.9.2.1.5.0= IpAddress:123.14.143.13SNMPv2-smi::enterprises.9.2.1.6.0= IpAddress:0.0.0.0SNMPv2-smi::enterprises.9.2.1.8.0= INTEGER:105670264SNMPv2-smi::enterprises.9.2.1.9.0= INTEGER:1117SNMPv2-smi::enterprises.9.2.1.10.0= INTEGER:500
...... The following omit ...

The purpose is now achieved, but we cannot remember this fixed string of numbers in front of each OID, so for the sake of memory, the aforementioned . 1.3.6.1.4.1 This prefix can also be written as Enterprises, so that We just have to know the different vendors ' own child node IDs.

The following is a list of the IDs used by common vendors (data source: http://oid-info.com):
