     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 
>> anything else.
     
     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.
     
Cordially,

     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!
