SNMP学习笔记之SNMP树形结构介绍（snmp之下有几棵主干树）

Basic command of SNMP:

GET: The GET operation is a request sent by the manager to the managed device. It is performed to retrieve one or more values from the managed device.GET NEXT: This operation is similar to the GET. The significant difference is that the GET NEXT operation retrieves the value of the next OID in the MIB tree.GET BULK: The GETBULK operation is used to retrieve voluminous data from large MIB table.SET: This operation is used by the managers to modify or assign the value of the Managed device.TRAPS: Unlike the above commands which are initiated from the SNMP Manager, TRAPS are initiated by the Agents. It is a signal to the SNMP Manager by the Agent on the occurrence of an event.INFORM: This command is similar to the TRAP initiated by the Agent, additionally INFORM includes confirmation from the SNMP manager on receiving the message.RESPONSE: It is the command used to carry back the value(s) or signal of actions directed by the SNMP Manager.

OID:

This is a sample structure of OD:

Iso(1).org(3).dod(6).internet(1).private(4).transition(868).products(2).chassis(4).card(1).slotCps(2)-cpsSlotSummary(1).cpsModuleTable(1).cpsModuleEntry(1).cpsModuleModel(3).3562.3

or just:

1.3.6.1.4.868.2.4.1.2.1.1.1.3.3562.3

Private OID:

Many manufactures can supply custom MIB files for their hardware ,such as temperature , fan speed.

The MIB file is hard to read, they are only meant to be imported, or "compiled " by a Management Station.

Below is an example of Cisco MIB file for environment monitoring.

Cisco MIB information:

​​MIB file:

The files below is F5 MIB file.

We can use MIB Browser to load these file ,and you can see the F5 private OID in the picture.
