Analyze test results

After you scan a device, the following sections guide you in understanding the results for the different test targets.

Discovery, layer 2, layer 3 and DNS

In the Session Data menu, you can find some items with Job Statistics suffix. If you select one of those, it displays an overview of the selected job where you can verify how the device responds to UDT requests for specific OIDs (Type and Status) and how long it takes (Duration). This identifies if the device is currently not supported by UDT or it timeouts on some requests.

The other items in the Session Data menu give detailed information about the selected object (OID) and what data it returned. The item always belongs to the nearest Job Statistics parent above.

Below is a very brief description of some of the objects UDT query to get the data. To get more details and understand what the individual values mean use the Cisco SNMP Object Navigator.

Discovery and layer 2 job statistics

These two jobs query are similar to OIDs.

Consult these objects about ports (port index, name, ifType, speed, trunk mode etc.) if you think the data UDT displays for the device ports are incorrect.

  • ifTableInfoCols
  • ifxTableInfoCols
  • dot3StatsDuplexStatus
  • dot1qVlanCurrentTable
  • vmMembershipSummaryTable
  • vlanTrunkPortDynamicStatus

Consult these objects about endpoints (MAC addresses) and to which ports they are connected if UDT is not displaying a specific endpoint.

  • dot1dTpFdbTable
  • dot1dBasePortTable

Layer 3 job statistics

Consult these objects about endpoints (IP addresses) and their mapping to corresponding MAC addresses to find what the device whose IP address UDT cannot see is returning for the IP-MAC.

  • ipNetToMediaTable
  • ipNetToPhysicalTable

If the device does not support those objects, UDT cannot get any layer3 information.

DNS Job

The table shows the IP addresses for discovery and the names to which they resolve.
