Using the MIB Browser

If you do not know the object ID (OID) of the SNMP attribute you would like to monitor, you can use the interactive MIB browser to load MIB files and walk or query any SNMP object on a device.

Loading MIBs

By default, the MIB browser is loaded with two popular MIB files: IF-MIB and HOST-RESOURCES-MIB. If your device has specialized SNMP object IDs, you will need to obtain the appropriate MIB file from the device vendor and load it into the MIB Browser. In addition, MIBs may have dependencies on other MIBs. You may be required to load other MIBs to support the MIB you want to load and use. The MIB Browser notifies you of the dependency if you attempt to load a MIB file that requires another MIB file that's missing. A set of MIB files are installed with your DGE extension at <Traverse_Install_Directory>\lib\mibs.

Note: loading a MIB in the browser does not impact the display in the Event Manager or elsewhere in Traverse. The MIB browser is just a utility to help you browse and select an OID for inserting into an advanced SNMP test.

Accessing the MIB Browser

From the Administration tab:

  1. Navigate to Administration > Devices.
  2. Click Tests on the line for a device, and then click Create New Advanced Tests.
  3. Click MIB Broswer under Simple Network Management Protocol Tests.

From the Status tab:

  1. Navigate to Status > Devices.
  2. Click on a device name, and then click Additional Tools.
  3. Click Go on the SNMP MIB Browser line.

Querying a Remote SNMP Device

  1. Select File > Load MIB and browse your local computer for the MIB file(s) to load.

  2. Select the primary MIB first, and then satisfy dependency by selecting any supporting files that are referenced. Once a MIB has been loaded, it remains persistent in the MIB Browser until you unload it, by selecting File > Unload MIB or File > Unload All.

  3. Set the different device parameters such as Device Name/Address, SNMP community string, port number (standard 161), version.
  4. Select either GET or WALK from the Operations menu. Note that a GET will only work on a leaf node (a node in the tree without any children), whereas a WALK will display all SNMP variables and values below a selected branch node. It is recommended that you do a WALK operation on the subset of the tree that you are interested in, and then do a GET on the final metric that you would like to monitor using Traverse to verify that the GET operation works.

  5. If you accessed the MIB Browser from the Administration tab, you can select the OID that you would like to provision into Traverse, and click Select OID for Test Creation. This will automatically insert the OID into the Advanced Test creation page.
  6. You can close the MIB Browser window after you have added the OID.
