RE: DPU Nodes reported Down/Up by Netmon

Santosh,

you should contact support.
They have to analyse a netmon trace to find the real reason.

One posibility is that the ping is redirected more than once.
Netmon will interpret the second icmp redirect as an error.
If so, you should first try to fix your network configuration.

But there is also an efix for IY20714  available.
With this fix netmon will do as many retries you have configured in your
snmp configuration.
Of course you have to go to NetView 6.0.2 first.

Kind regards
Oliver Bruchhaeuser

Hi,

I tried setting the SNMP polling interval and timeout as high as possible
but still trapd.log gets updated with Netmon events for these DPU's at very
fast Down/Up events. Where else could be the problem.

Santosh

   Put an entry for these devices in your ovsnmp.conf (Options -> SNMP
   Configuration).  I would suggest increasing both the timeout interval
   and also, perhaps, the retries if the lines are a loss-y.

   Cheers,

     Hi,

     I have Netview 6.0.1 on AIX 4.3.3

     We have almost 180 DPU (SNMP Not supported) locations on slow link in
     our Wide Network. It is reported in trapd.log that very frequently
     they go Down and come Up so fast (which could be because of slow link
     response). If I do a query to database for these DPU's Up/Down status,
     it becomes a huge and non relevent data.

     Can I have some solution for this so that the genuine DPU Down and Up
     will be reported to trapd.log

     Santosh
