Re: NetView Discovery Problem in 6.0.1

[Walt_Ostack@tivoli.com]

Joe,
In NetView 6.0,  new code to use the Cisco CDP information was implemented to
improve the discovery of unnumbered serial interfaces.
As a part of this, the netmon parameter to discover unnumbered interfaces was
made a default. I suspect, your discovery problem is
related to the discovery of nodes linked by these unnumbered serial interfaces.
I suggest turning off the discovery of nodes linked by
unnumbered interfaces to observe its effect on your problem.  Go to Serversetup
->Daemons ->Netmon ->Discovery and uncheck
"IP Nodes beyond Unnumbered Interfaces".

Subject:  [NV-L] NetView Discovery Problem in 6.0.1




I recently upgraded my system to NV 6.0.1 for NT to solve the SNMP data
collection graphing problem (APAR# IY10046) which worked. However it has
created a new problem.  I have been using seed file discovery/seed nodes
only to control the scope of my network management areas. When I upgraded to
NV 6.0.1 my entire network now gets discovered. I cannot stop or control the
discovery process.  After close examination of the netmontrace log netmon is
using CDP (CISCO router environment) and discovering the next hop routers
then going out and discovering the next hop routers off the pervious
discovered set.  Within minutes I have a mess and routers added I do not
want.  I opened a PMR. This seems like a new bug. Comments/suggestions. I
cannot use the product in this state!
