Sure, if you take a port that you can disconnect without causing any issue then you can go to the DFM detailed device view and put the port in a managed state.
To do this goto Monitor -> Fault Settings -> Setup -> Fault Device Details, select the device with the port you want to manage, and in the screen that appears click again on the devicename.
Under interface status select the port and change the managed state to true and hit submit and apply when it pops up.
Next time this port goes down you will se an event in Fault management.
When the device get rediscovered the state goes back to unmanaged.
Cheers,
