How about splitting the seed file and add sections
at time until we complete the discovery at a rate of 250 devices / cycle ?.
Initial cylce do the map regen, and subseuent cycles jut stop start net mon
?
We
should get some input from others on this. I would never say never. There have
been times when certain Cisco routers were badly affected by excessive SNMP
requests. Core switches should be a different case, I would think. My belief
is that if you don't have the network capacity for network management traffic,
then you don't have enough network capacity. In that case, you could
discover slowly.
Others may be
able to warn you about special vulnerabilities of specific devices.

Thank you Leslie..
Yes, I do have the need to do a regen.
Is my worry about any excessive traffic bringing a device down
unwarranted ? The reason why I ask, and am a bit afraid is that my predecessor
attempted to do a full discovery and brought down a core switch in one of the
buildings. Hence I am more careful with my discovery needs, and setting them
up accordingly.
We have an off site drp server, but it uses is strictly as
trap acceptor and sending alerts. We will not support mapping and db functions
in drp.
Hence my fear...
Thanks again,
John

Otherwise,
if you want to do a new discovery, the re-gen will stop netmon and everything
else, and go out and rediscover everything, depending on your discovery
settings.

| [nv-l] Newbie Question
- Auto Map re-gen and Net MON |
|
Hello
All...
I have a newbie question.
I'm in a
situation where one of the net view servers has been neglected for some time
and the map and db is pretty much useless. I have cleaned up the seed file,
and removed as many entries from the host file as I can as we would try to
rely on DNS for resolution as well I have created a Location conf file based
on our ospf areas.
What I'd like to accomplish is zero out the db's and
create a new map and have fresh db's (start from scratch).
My question is , do I
only need re-gen the map from the admin panel, to ensure everything is
discovered, or do I need to recycle netmon, then do a map regen ?
My concern is
that we have well over 1000 entries in the seed file (loop back address of
various L2 / L3 devices) and am concerned that the traffic may bring down the
switch or router, we are 7/24 hr shop so no chance of doing this during maint.
windows. Netview is configured to do only local discovery and seed file, no
wild card ranges defined.
The box is NV 7.1. AIX 4.3.3 on multiple 100
MB nics.
Thanks in advance
John Sobrinho
