Perhaps you are discovering it by an address that is not real?
If it is a vlan address, or perhaps an hsrp address, that will do
it. Force the discovery by an address (or name that resolves
to an address) that is an ethernet interface. Also make sure
that the address, if it resolves, resolves both ways.

Cordially,

Looks like your topology and object databases are having issues sync'ing
up.
Try looking in the object database also:
ovobjprint > ovobj.txt
then vi / grep on the ip address and the associated hostname to look for
clues.
Netview won't add duplicate IP address' into its databases.

You can also format the trap for duplicates that Netview finds:
IBM_DUPIP_EV {1.3.6.1.4.1.2.6.3} 6 58982415 N 1 0 "Log Only Events"
$3
EXEC echo " $(date "+%Y/%m/%d %H.%M.%S"): $1: $2: $3: $4: $5" >>
/home/root/duplicate_ip.log
SDESC
This event is generated by NetView for AIX when
it when a duplicate IP address is found

The data passed with the event are:
    1) ID of application sending the event
    2) Name or IP address
    3) Formatted description of the event
    4) IP address
    5) Database name
EDESC

Good Luck,
--Dermott

I do a locate and ovtopodump -l on both IP address and device name and it
finds nothing..

You have a duplicate IP address I would suspect. Netmon is deleting it when
discovery polls the "other" device. Just a guess on my part.

Hi All,
          I have an issue where I add a router to the netview map and place
it in its appropriate location bucket and then it disappears. I look in
netmon.trace and there is nothing. I look in trapd.log and I get N Node
Deleted. I then do a locate and it is not found in any map. I do an
ovtopodump -l and it is not found. I ping and snmpwalk the device with
success and then do a netmon -y and netview rediscovers it and then netmon
deletes it again.. Any help would be appreciated. Thanks.....
