This article provides a step by step guide on how to configure a Tekron clock over the Simple Network Management Protocol (SNMP) using MIB (Management Information Base) Browser.
Please follow the steps below to configure a Tekron Clock using SNMP.
1. To configure a clock using SNMP, you need a MIB Browser. If you don't already have one, then you may want to download the iReasoning MIB Browser – this article only applies to the iReasoning MIB browser
Note: Before downloading third-party software, please refer to the Tekron Third Party Software Disclaimer
2. Configure the SNMP settings in the clock using the Tekron configuration tool before configuring the clock using the MIB Browser. To configure SNMP settings in the device, go to the Network tab of the configuration tool, select the SNMP sub-tab and ensure the unit has read-write access. Refer to the picture below for guidance.
Figure 1 Read/Write access in the SNMP tab.
3. Download the Tekron MIB file from https://tekron.com/dmsdocument/24, extract the MIB file, and save the file in your system.
4. Open the iReasoning MIB browser and load the Tekron MIB file into it, as shown in the picture below:

5. Once loaded into the browser, the MIB file will appear in the MIB browser's mib folder, as shown in the picture below:
Figure 3 Capture shows the Tekron MIB file
6. Connect the PC or laptop running the MIB browser to the Tekron clock using an Ethernet cable.
7. Insert the IP address of the clock which you want to configure in the MIB browser, refer to the picture below for guidance.
Figure 4 Capture shows where to enter the IP address
8. Expand the iso.org folder in the MIB tree, as shown in the picture below. The TncObjects folder is the subdirectory that consists of the configurable clock settings.
Expand the tree as follows: iso.org>dod>private>v2mib>tncObjects.

9. Reading a setting over SNMP is called a "get"; changing a setting to a specified value is called a "set".
Each configurable setting has an OID (object identifier) value. The OID value uniquely identifies the setting.
The example below shows the OID Value for the tncNTPEnabled feature, which is .184.108.40.206.4.1.346220.127.116.11.18.104.22.168

10. This step shows how to configure the tncNTPEnabled setting but can be generalised to all other configurable settings.
Right-click on the tncNTP enabled setting and select "Get Next". Get Next command will allow you to read the existing value for the tncNTP enabled setting into the MIB browser. The right-hand pane shows the value True (1). The True (1) value shows that NTP is enabled.
Figure 7 Get Next Command shows the NTP is enabled.
11. To change a setting, select the "set" command, which will allow you to write over the existing value of the setting.
On the top side of the right-hand pane select "set" in the operations box then select go. This will cause the "SNMP SET" to appear. Enter the value in the "Value" textbox and click Ok as shown in the picture below.

12. All configurable settings on Tekron Clocks can be configured using the same approach.
A programming language such as Python can also be used for writing the scripts and configuring the clocks.
