Report on Interface Duplex Setting

You will need a UnDP to collect the duplex setting. Most (cisco) devices support the etherlike mib so 1.3.6.1.2.1.10.7.2.1.19 would be a good place to start. Then edit the Current Interface Status report in Report Writer to include the new data

Ok,  I created the custom poller for that MIB.  I then edited the report but I don't see how to display the results of the poller.

Thanks

If the custom poller option doesn't appear in the drop downs you may need to experiment with other report types or it might be simpler to start a new report and select the sql option then paste something like

SELECT     CustomPollers.UniqueName, Interfaces.InterfaceName, CustomPollerStatus.Status

FROM         CustomPollerStatus INNER JOIN

                      CustomPollerAssignment ON CustomPollerStatus.CustomPollerAssignmentID = CustomPollerAssignment.CustomPollerAssignmentID INNER JOIN

                      CustomPollers ON CustomPollerAssignment.CustomPollerID = CustomPollers.CustomPollerID INNER JOIN

                      Interfaces ON CustomPollerAssignment.InterfaceID = Interfaces.InterfaceID

WHERE     (CustomPollers.UniqueName = N'dot3StatsDuplexStatus')

into it 

Add as many fields from the interfaces table as you need

dot3StatsDuplexStatus should be replaced by the name you gave your UnDP

FYI, this UnDP didn't work for me for my routers, but the UnDP here did.  good luck
