You are right, Ken, addresses are safer, since netmon will lay down
and die if any name in the seedfile is not resolveable at startup time.
The trade-off is administration. It is sometimes harder to recognize
the addresses, and sometimes the addreses change. I also like to
be able to extract a list of routers from the discovered database and
use that for subsequent seedfile generation, and those of course
come out as names. Either way.
There is also the case where your DNS returns addresses round-robin
style when you resolve a name. In that case I think you are better off with
addresses, since they should always resolve to the same name.

Leslie, would it be better to put the one interface in the seed file with
the
assigned DNS name or the IP address of the assigned DNS name? What would
be the
result of either instance. I currently put the IP address in the seed file
in
the event that there is a problem with resolution. The primary and
secondary DNS
servers run outside of the NetView system.

Alexis, it is ok to have different names on each interface. But you must
put only ONE of them in the seedfile for each node, as Paul said. Pick the
loopbacks, if they have them. Now take netmon down, delete all of those
things from the map, and anything related to them. Close the map. Do an
ovtopofix -a. And restart netmon, and the map. At this point you will be
doing
it right. If you still have a problem, then something unusual is going on.
But as it
stands, you can expect wierd things if a device appears more than once
in the seedfile.

I put 6 interfaces for each router in my seed file, because each resoves
with a
different name in the DNS.
I have neither way nor authority to change this features.
Then i tried to add this interfaces in my /etc/hosts in order to have only
one
name for each router.
Some routers are now discovered but others are not. What is really strange
is
that netview discovered 4 routers (say router1, router2, ..., router4) wich
are
all connected to a router named sysa, but does not appear in any submap (i
have
only one map).
I tried to demand poll on router1 to router4 but i can't discover sysa.
If i use ovobjprint i have:
ovobjprint -s sysa
OBJECTID SELECTION NAME
OBJECT: 536
FIELD ID FIELD NAME FIELD VALUE
10 Selection Name "sysa"
11 IP Hostname "sysa"
133 XXMAP Protocol List "IP"
560 IP Name "sysa"
Any help would be grateful.
Thank you.

Did you happen to seed all the interfaces for our core router in the netmon
seed file? You should seed only one interface per router (one that resolves
in the DNS perferably).
