Re: [NV-L] Frequently Node Down-Up events

I'd guess that is exactly the problem. The polling defaults are good for your subnet, the one NetView is on. Distant devices or ones slow to respond will require longer time-outs. You need to adjust them to what works in your network. This is a tuning issue.

Subject	[NV-L] Frequently Node Down-Up events

Hello,

I often see DOWN-to-UP messages of my network devices lasting only for
few seconds. This applies to some Switches as well as Access Point we
are monitoring. 
I can't see anything on any log files on the network devices to verify
the downtime "supposedly captured" by netview. Is this a result of the
polling-timeout-retry combination we have? Or is there already something
wrong with my netview?
Netview 7.1.4 on Linux Red Hat ES4.
I'm using the Polling default value.

Regards,

Mauro
