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 similar 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.
n ifTableInfoCols
n ifxTableInfoCols
n dot3StatsDuplexStatus
n dot1qVlanCurrentTable
n vmMembershipSummaryTable
n vlanTrunkPortDynamicStatus
Consult these objects about endpoints (MAC addresses) and to which ports they are
connected if UDT is not displaying a specific endpoint.
n dot1dTpFdbTable
n 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.
n ipNetToMediaTable
n ipNetToPhysicalTable
Note: 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.
