Re: [nv-l] Duplicate IP Address

[Gareth Holl <gholl@us.ibm.com>]

I don't think the NMAVAILABILITY variable has anything to do with the integration with the Tivoli Enterprise Data Warehouse (could be wrong) because the variable TDWAVAILABILITY in the /usr/OV/conf/netmon.conf file is used to disable/enable the NetView Warehouse integration function. If enabled, availability data is written to a DB2 database and not a file.

I assume this is for the Tivoli Data Warehouse integration.

What does this option do exactly in /usr/OV/conf/netmon.conf:

# Set to TRUE to enable writing the availability file
#NMAVAILABILITY=FALSE

Scott,

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
-----
On NetView 6 I would recommend to turn on a full netmon trace for some time
with "netmon -M -1".
And:
grep Duplicate /usr/OV/log/netmon.trace*
from time to time.
This will show you something like:
10:47:28 : .//nl_snmpstate.c[6971] : Duplicate IP address 10.100.50.3 on
tivnvcisco1 and tivnvcisco2

Hope this helps ... and don't forget to stop the netmon trace again with
"netmon -M 0".

Kind regards
