These are traps generated by NetView ("N" source
symbol) identifying interfaces found during a demand poll of the router.
This may have been from the demand poll during discovery of the node, from a
demand poll issued following a loadhosts or manual definition of a router
or from a demand poll issued during the daily configuration polling cycle.
They were added to the NetView Object Database and the trap
notifies you of that action.
The interfaces were there in the router database
all the time (as your network engineers stated) and whether the interfaces are
down or up they were found in the Interface Table and possibly the Address Table
on the router when queried by SNMP.
I don't remember what platform you are using but I
suggest you re-read Chapter 6 of the NetView for Unix Administrators Guide or
Chapter 8 of the NetView for Windows User's Guide as appropriate. The
information in this chapter isn't the best organized but it's all there
somewhere in the chapter. It was also covered in the NetView for Unix
for Administrators course the last time I taught it.

Subject: [nv-l] "Down" router
sub-interfaces show as "Added"
NV 7.1.3 / AIX
5.1
The router people claim that the
(Added) traps for a router sub-interface showing up in their event window (see
below) are incorrect as this sub-interface has been consistently down for past
several days, and there are no entries in router log files for such
addition.
There are several of these traps
for several sub-interfaces.
These are Netview generated traps
(SPECIFIC: 58785792, GENERIC 6 - ENTERPRISE
netview6000). Any reason why Netview would detect these down interfaces as
Added? Thanks.
