SNMP Object

SNMP Object

Hi there,
as a test, i have written a program sending a trap to all snmp-agents in my network. after that i read all informations of the agents out. yes, it works!
Now my question. How can i know what kind of agent (devicetype like printer, switsh, pc, etc.) is answering?
i want to act like this: if an agent is answering me, i want to ask him what kind of device it is, and then asking only special properties.
example: device is printer -> ask RFC 1759.
anyone have a solution?
best regards

RE: SNMP Object


You need to perform an SNMP request of the sysObjectID for the agent/device you want to know about.

This sysObjectID definition is as follows:

The vendor's authoritative identification of the network management subsystem contained in the entity. This value is allocated within the SMI enterprises subtree ( 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, it could assign the identifier to its `Fred Router'

So you can perform a check on the value returned for sysObjectID and then if it is your printer then -> ask RFC 1759.
