Re: [NV-L] NetView Discovery Issues

[Leslie Clark <lclark@us.ibm.com>]

You don't even need SNMP access to get
them discovered. So something more basic is wrong.
Is this a Unix or a Windows server?

Check these things:
1) If you are using a seedfile, does
it exclude the range of addresses that you are trying to discover?
2) Have you tried putting the router
and switch addresses in the seedfile?
3) Is the map you are looking for them
in a r/w map up?
4) Are you sure they are not in there
already, maybe on some other node than you expect?

For that last one, try
nvUtil e '("SNMP ipAddress"
= "xx.xx.xx.xx")'

5) Remember that a range in the seedfile
only allows discovery, it does not force discovery. If they are found in
the arp cache of an existing device, and they are allowed by the seedfile,
they should be discovered.

6) Be sure you are not discovering by
a virtual address. Try using the loopback address of the device. To tell
if you are using a virtual, try

   rnetstat -Ix xx.xx.xx.xx
and check the output to see if that
address is in the list of addresses on the device. If it is missing, Netview
will discard the node. 

7) If you have more than one map, and
the things were previously discovered in one of them, they must be deleted
from all maps before they can be rediscovered.

8) Do these commands to reorg things
that might have gotten out of wack:
   ovstop netmon
   ovtopofix -a
   ovmapcount -a
   ovstart netmon
   close and open the map
Cordially,

Subject	[NV-L] NetView Discovery Issues

All,
I have 2 routers and 2 switches on the same subnet which
NetView 7.1.4 won't discover.  Each device is reachable via Ping and
each one responds to SNMP polls.
 
Can someone let me know which MIB objects NetView reads
and uses in order to add new subnets and /or devices? 
 
Thanks In Advance,
Stephanie
