Here's my two cents. I'm not the netmon guy, but there is a debug process
to follow here.
Each NetView is independent of the others, so you have to solve your
discovery problems on each one separately. Divide and conquer.
First, I would pick a NetView and do an snmpwalk of the router without
specifying a community name, and redirect the output to a file. The
command should use what you have defined in for SNMP configuration. If
that succeeds you can rule out SNMP access as the issue. Then examine the
SNMP output and verify that all the interfaces you are looking for are in
the ifTable. If not, then that's why they aren't discovered. If they are
there, then that's not the issue either.
OK, so let's assume they all show up in the snmpwalk output. You said
some are "leased-line". Does that mean they represent serial connections?
NetView won't draw a serial connection unless he can see both sides of
it, since it is just a straight line between boxes. And he won't show a
serial interface if he cannot draw the connection. So you must discover
both sides of the connection to see the interface. That may be why some
of your NetViews can see it and some cannot. Rectify your discovery
problems by putting both ends of the link in the seed file and restarting
netmon.
Frame relay? Offhand, I don't know why netmon would have a problem with
that, but your best bet is to contact Support and open a problem. Why?
Two reasons I can think of. First, because there have been netmon fixes
out since the FixPack and you might need one or more of those. Second,
because ultimately you can get a netmon specialist to help with the
discovery. There are people whose job it is to get to the bottom of
these things.

all the community names are correct. read access community is public.
write access community is different but it does not matter. I write this
community in communitynames. the problem is not community I think because
it finds routers. Only do not show some interfaces(most of them are frame
relay) - show unnumbered interfaces option is active.
thanks.

Subject: [nv-l] NetView can not find some interfaces
Hi everbody,
I have NetView 7.1.3 for NT with fixpack on Windows2000 Server wtih
service
pack3.
I discover my network and see that some interfaces on some routers are not
found(some of them are leased-line and some of them are frame-relay).
For example, I have a router and I configure 10 interfaces of it. I show
six of them on NetView but four of the interfaces are not shown. I
activate
cdp for these interfaces. But still nothing is changed. The strange part
of
it that I install another NetView for testing , and see that the new one
can
find these interfaces but on the other hand can not find some of the
interfaces that the first NetView found before. I can not understand what
is happening. I have about forty routers in my network and now I can not
see
about 15 interfaces of them.
Does anyone have any idea?
Thanks.
