Is the MIB also reporting the mask for Serial interfaces as 255.255.255.252
?
Sooner or later if we can not solve the problem here, you are going to
need to get a netmon trace of the discovery of the 2 routers on either end
of a serial link. Then either search through it to see if you see some
strange data, or get support to look at it.

All ifType are the same (Point to Point Serial (22)), all routers are Cisco
2600.

Perhaps some of your 'serial' interfaces are not considered to be serial by
Netview.
It will probably depend on the mib value ifType returned by the snmp agent
for
that
device. For instance Frame Relay interfaces return a '32' for ifType and
Netview
draws
bubbles for them. In V5 there is a file that lets you configure more things
in
this
respect. See /usr/OV/conf/C/if_to_sym for information on this. And if you
select
an interface card and do a 'Tools..Display Object Info', you will see which
number,
or ifType, was returned by the agent for that interface.

Yes, you were right about being able to click in the line and get to
antoher sublevel on the map (why didn't i think of that =))
But I still don't understand why i get these bubbles on some routers and
not
on others,
because it is serial interfaces and not LAN interfaces and if i understand
you correctly
then netview should just draw a line between the routers and not make a
"bubble" since
it's a serial link?
The router config looks something like this:
Router 1
Lan If: 192.168.0.1/255.255.255.0
Serial If: 192.168.50.1/255.255.255.252
Router 2
Lan If: 192.168.1.1/255.255.255.0
Serial If: 192.168.50.2/255.255.255.252
The bubble I between these to says 192.168.50.0, and that's fine with me,
but I should
have gotten a straight line?

Christian, perhaps your expectation is incorrect. In Netview, serial
networks
are drawn
(for some reason) as straight lines between two (or more!) routers. They
are
different
from LAN interfaces which are drawn as bubbles, what I think you are
calling
link-nets.
This is working as designed. If you double-click on that serial network
(the
line) it will
show you a network submap just like the bubble networks. Its properties are
the
same,
for the most part, it is just visually different.
There is one other difference. If a router has an ethernet interface on a
subnet
with
no other router on it, the network icon is still drawn. But for a serial
network, that
line is NOT drawn (since it has no place to go!). Therefore, to see a line
for a
serial
interface on the IP Internet level of the map, you must also discover the
router
on the
other end of that line. For this reason, the number of cards under a router
will
sometimes
be greater than the number of lines coming out of the router on the top
submap.
Under File..Describe Map, you will find an option to have serial networks
drawn
with
different kinds of lines (like dashed or dotted), which can sometimes
clarify
things,
but there is no option to draw it as a circle.

We have just thrown out a bunch of decnis routers and replaced them with
new
cisco
routers. All of these routers have linknets configured but only 2 of 8 is
shown on the map
(the linknets, ip-net icon) the others are just directly connected router
<-> router without
the linknet in between.
What I have managed to find out is that all the routers that are not
connected thru a link-net
on the map has more than 1 ethernet adress, the other 2 are just 1 ethernet
adress and 1 serial.
Is there some way to "fix" this so i can get all my link-nets appear on the
map?
