Anil,
sorry, but I have some problems to understand your second paragraph.
Before setting the env var "NV_NETMON_REPORT_DUP_ADDRS_ONLY=TRUE" there was
a node deleted due to a duplicate IP address. Right?
Now you have corrected the duplicate IP Address and want to discover the
node again. Again right?
Is this a node with more than one interfaces?
What IP address is in the seedfile (if any)? The duplicate IP addess? The
new corrected duplicate IP address? Or the IP address from another
interface?
Kind regards

Oliver,
Thanks for providing all the details.
I set the variables using netmon.conf and checked using
Netmon -a 160. It did not add the env.
But when added these environment variables using
/usr/OV/bin/netnmrc.pre, I see the env added.
Now, I am getting duplicate IP event.
But, I earlier defined NV_NETMON_REPORT_DUP_ADDRS_ONLY=TRUE.
As a result, Netview deleted the duplicate IP node from the
Map. How do I initiate discovery at my will to get the
Deleted symbol back. I have already rectified the duplicated IP.
Thanks,
-- Anil Kumar

Anil
both environment variables nothing have to do with each other.
-----------
DCF Document ID: 1063371 - IBM Tivoli NetView: Definition of
NV_NETMON_GENERATE_DUP_ADDR_EVENT Problem Desc: A more concise description
is needed of the environmental variable NV_NETMON_GENERATE_DUP_ADDR_EVENT
found in "/usr/OV/conf/netmon.conf"?
Solution: The environmental variable "NV_NETMON_GENERATE_DUP_ADDR_EVENT"
allows netmon to either generate a duplicate address events whenever a
duplicate address is encountered in the network or to not generate the
event.
NV_NETMON_GENERATE_DUP_ADDR_EVENT=TRUE, will generate a duplicate address
event as in v5. NV_NETMON_GENERATE_DUP_ADDR_EVENT=FALSE will surpress the
duplicate address event.

DCF Document ID: 1063439 - IBM Tivoli NetView: Improved "netmon.conf"
definition of NV_NETMON_REPORT_DUP_ADDRS_ONLY Problem Desc: A more concise
description is needed of the environmental
variable: NV_NETMON_REPORT_DUP_ADDRS_ONLY, found in
"/usr/OV/conf/netmon.conf".
Solution: When netmon encounters a duplicate address in a network, it
moves
the interface to the "last seen" node. This may cause an interface to
"float" from node to node. Setting the parameter to TRUE will cause netmon
to only produce a trace message. The interface will remain on the node
where
it was first discovered.
NV_NETMON_REPORT_DUP_ADDRS_ONLY=FALSE
Set to FALSE to report duplicate IP addresses and remove them.
NV_NETMON_REPORT_DUP_ADDRS_ONLY=TRUE
Set to TRUE to report duplicate IP addresses but will not remove them.
-----------
You have to restart netmon after making the changes to netmon.conf.
You can dump netmons environment variables to /usr/OV/log/netmon.trace with
"netmon -a 160".
Hope this helps.
Kind regards

Oliver,
Thanks for a quick response.
Yes, I removed the # in front.
Also, I see another entry.
# Set to TRUE to report duplicate IP addresses, don't remove them.
#NV_NETMON_REPORT_DUP_ADDRS_ONLY=FALSE
I also tried setting this keyword to TRUE (and removing leading #) along
with NV_NETMON_GENERATE_DUP_ADDR_EVENT=TRUE
Still, I do not see Duplicate IP event.
(Though, I am not sure what these keyword do together or separately. I
searched all online docs of Netview for rev 7.1, 7.11 and 7.12. But search
could not find any reference to these keywords in any of these docs.).
Please suggest, if I can check out some other settings or enable some Kind
of trace of netmon which may suggest if it is getting right environment
etc.
Sincerely,
-- Anil Kumar

Hello Anil,
did you also remove the hash (#) in front of
NV_NETMON_GENERATE_DUP_ADDR_EVENT=TRUE
?
Kind regards

HI Oliver,
I saw your your posting relating to detecting duplicate IP with Netview
7.1.2 :
>unfortunately on NetView 6 no more duplicate ip address traps are
generated
>as it was on NetView 5.
>On NetView 7.1 this feature can be reenabled by setting the following
>netmon option in /usr/OV/conf/netmon.conf
>-----
># Set to TRUE to generate a duplicate event as in v5
>NV_NETMON_GENERATE_DUP_ADDR_EVENT=TRUE
I AM USING NETVIEW 7.1.2 and did what you suggested and than restarted
all
netview deamons. I than assigned an IP of the exiting node to an interface
of an another existing node.
I see events such as "link address is different than earlier". But I do not
see duplicate IP events. Am I missing some step?
Thanks in adavance for any help.
Thanks
