SNMP OID

OIDs are a crucial part of SNMP and SNMP Management

SNMP OIDs Are the Leaves on the MIB Tree Structure

The branch of the MIB object identifier tree that represents managed elements used by DPS Telecom equipment.

What does an SNMP OID look like?

Here's an example: 1.3.6.1.4.1.2681.1.2.102

OIDs are crucial in the assembly of SNMP messages. An SNMP OID functions as an address that identifies the location of a specific element within the entire SNMP network. The translation of OIDs allows the SNMP manager to determine values for these objects. The MIB assigns readable labels to each OID, which allows the manager to interpret and assemble SNMP messages. Without the OID, the message cannot be translated into a form that is readable to humans.

When the SNMP manager requests the value of any object, it assembles a message with the OID, which is sent to the MIB for decoding. If the OID is listed within the MIB at that particular management station, a message is sent back to the manager including the value requested for that particular OID.

Objects Not Listed in the MIB Cannot Be Monitored

While each SNMP OID is unique, the first several pieces of each OID are almost always the same. These upper location levels are defined by a series of standard reference within the MIB. These series are called RFCs, or Requests for Comments. The RFCs that define SNMP OIDs are part of a larger group of RFC documents that define the Internet as a whole. Individual vendors create their own MIBs that only include the OIDs associated specifically with their device.
