No. That list is of the networks, and you are right, Netview does discover
all interfaces on devices and makes networks for them. That's what they
developed the location.conf file for - to help put away those fans.
Consider
the number of subnets that will be created when you are deciding how to
subdivide your seedfile for staged discovery. For the ones with many
interfaces, do them one at a time, putting away their networks first. But
we have to have all of the networks if we are going to have a properly
connected map in the end.

Subject: Re[4]: [NV-L] Discovery Suggestion
Leslie,
First off, I really appreciate all of your help on this!
Let me explain what I mean about multiple entries for an object. When
I start my discovery, My map begins to fill very rapidly. I turn off
auto layout for the IP Map. This then places all of the new objects in
the New Object holding area. To manage these objects better, I select
them all and hide them from the IP Map.
Now, When I am ready to deal with these devices, I go into the Hidden
Objects Dialog box and I see multiple entries for a single device.
Example, I have a router called rnwgent1 that has over 200 interfaces
defined. This router shows up in the hidden items list about 200
times. Once for each interface.
What I was wondering is if there is a way to have netview detect the
Loopback address ONLY and have one entry in the list?
Thanks again!
Chance

Chance asked:
If I use a piecemeal seedfile, how do I keep it from discovering
networks that I haven't specified in the seedfile?
This is what has overwhelmed me before. I specify a small seedfile of
maybe 2 or 3 networks. I come back the next day and my map has fans
all over it.
>> Put a range in the seedfile, like 1.1.1.1-10, that won't allow

Also, Every router has at least 3 interfaces. Is it required that
Netview create a seperate object for each interface? Or can I
configure it so when an object is discovered it checks to see if the
object exists before creating it? That is one of the many confusing
parts for me.

No matter what you do with the location file, if you start up Netview with
4000 routers, you will get at least 4000 dots on the IP Internet level of
the
map. Remember that only the networks get cut into the locations. You
will have a really hard time cutting and pasting that.
You will have to discover the network piecemeal. So start segmenting your
seedfile now. Make lists of just routers, grouped by some reasonable
criteria. Geopgraphy maybe. Include in each section a bogus range to
prevent
discovery of anything except what is in the seedfile. Only include as many
routers
as you would want to see on the top map at one time. Like maybe 50?
Certainly less
than 100. Note that when you have networks placed in locations for you,
the routers
left on the outside will result in extremely dense fans, which will make
them very difficult to
select. Prepare to select by name, with 'Locate...' and then
'View...Hightlights...Select
Highlights'.
Hubs, etc, are not an issue. They appear only at the lower levels of the
map so you
can put them in the seefile later.
Prepare to do this over several times until you figure out the best way for
you.

I am running Netview 6.0.1 on AIX 4.3.3
I have the IP addresses of all devices in a flat text file. I am
looking for recommendations on how I go about building my map. I am
fairly new to Netview and I am having trouble getting it to come up
ok. I have just over 4000 routers and a whole slew of switches. There
are a few workstations that I would like to manage, but not all of
them.
I had problems with my location.conf file. Tivoli has released an APAR
and are currently working on a fix. Aparently, when you have a file as
large as mine, over 2500 lines, ipmap cores every few seconds trying
to keep up. As soon as this is fixed I think the location business
will be fixed.
I would like this process to be as automated as possible. Any
suggestions would be greatly appreciated!
