Now, you can start control the DtGrabber+ through SNMP. SNMP Traps will automatically be sent

to all authorized SNMP Managers.

6.4. About the OID and MIB Structure of SNMP controllable DekTec functions

Multiple combination of DekTec adapters and applications can co-exist a single computer/server,

which is identified by its IP address. Each DekTec function is identified by its OID node but to

differentiate between the multiple adapters and application a specific OID structure has been

designed.

The OID root [1.3.6.1.4.1.27070] is common to all DekTec functions running on the host computer.

Consecutive values designate, by order, the Application Id, the Application Inst, the TrapOrObject

Indicator and finally the part which is application dependant.

 The Application Id is unique for each DekTec application controllable by SNMP. For instance,

the Application Id for DtGrabber+ is the integer 0x04. The Application Id value can not be 0x00

(zero).

 The Application Inst indicates the instance number of the application for this Application Id.

Depending on the Application Id, this value can be either an index related to the DekTec

adapter attached to this application, or an cardinal order referring to the order in which the

several instance of this application where started; ex: the first application to be started will

receive the instance number 0x01, the second 0x02, etc..

 The TrapOrObject indicator distinguishes between Trap (0x01) or Application Parameters and

statuses (0x02).

For understanding of the Application Dependant field, please refer to the MIB file included in the

Installation Package and copied into the [C:\Program Files\DekTec\DtGrabber+] directory.

The following graphs illustrate the MIB structure for DtGrabber+ functions.

For understanding more about the MIB file structure and syntax, please refer to RFC 1213,

"Management Information Base for Network Management of TCP/IP-based internets: MIB-II"
