Perfect and as always great information.  The reason I asked about
turning off new node discovery is that we may double the number of
managed devices and the devices are located in another part of the state
(NY) connected by a 100Base-FX link and conserving bandwidth may become
an issue.
 
Thank you,

Subject: RE: [NV-L] SNMP polling config file(s)



If you are getting a path error using Help, then there is a problem with
your installation. The Help pages are displayed by a browser such as
mozilla (nee Netscape) and you have to have that installed and whatever
environment variables it needs (such as MOZILLA_HOME) already set before
you start the NetView GUI.

I'll answer question two first.

Configuration polling is something netmon does daily by default via SNMP
to see whether the anything it knows about a devices has changed, such
as the number of interfaces, their speeds, and so on.

So the answer to question one is that turning off New Node Discovery for
an individual device or a group (Smartset) of them does not affect
Configuration Polling of a device. New interfaces will on an existing
device will be discovered by the Config check.

IMHO the only reason you should be removing a device from new node
discovery is if it has been definitely shown that querying it causes a
problem of some sort on that device.

BTW, you can shut of new node discovery all together via a pull down
from the GUI Options --> Topology / Status Polling Intervals. And you
can restore it later the same way.

OK,

thanks for the very good answer. I tried the help button in the SNMP
configuration dialog box but I receive an error regarding a path. I also
check the manuals on line and which are the same as I have in paper form
and no mention of what all the fields do. So I am guessing and don't
want to guess.

Perhaps you can help me get help working or help me understand a few
fields.

1. If I deselect/uncheck the Discovery Poll for a specific node or
Smartset, netmon will not use this device (or in the case of a Smartnet)
or devices to discover new nodes. Will NetView still discover new
interfaces on an existing device if Discovery Poll is unchecked?

2. What does Configuration Polling Interval do? Polling the
configuration of a device for what? Is this discovery Polling? Are
Discovery polling and Configuration polling the same thing?

Thank you for your valued help,
