This is a clip from my PMR on authentication failures - you may want to
review it.
4. pmr82387 ->aparIY22983:
This was the Authentification traps you were getting, caused by the use
of an incorrect community name for the first x number of request in a
series before the correct one was sent. I know you are getting hit with
non-netvew traps on your nt machines now, so you may not have any
information on the results of this fix. When you do let me know.
(this did fix the problem)

Hmm... I can understand the problem clearing when you restart netmon. That
would probably be the equivalent of doing an xnmsnmpconf -clearCache.
So might that have something to do with redirects? If the Netview is on
AIX,
you might check the value of 'no -a | grep ipignoreredirects'. If it is 0,
try
setting it to 1. When the problem occurs, does the ip address listed in
'xnmsnmpconf -resolve <selection name>' change from the good address
to the bad address? I don't know what any of this means, it is just my
voodoo approach to problem determination.....
Cordially,

I would like to know how you resolved the failing SNMP status poll issue. I
am monitoring a hosting environment in which most servers have more than
one address, but the NetView server only has routes and (filter) permission
to specific interfaces. I am using SNMP status polling and I am not using
DNS for name resolution. Instead, I place a single hostname entry for the
accessible address in /etc/hosts. NetView discovers and polls most hosts
correctly. Occasionally, and only for certain servers, NetView starts using
one of the unreachable addresses for SNMP status polling. If I recycle
netmon, NetView starts using the correct address again. I have been unable
to determine the circumstances under which the change takes place.
