My question is how to delete a Node completely from the NetXMS installation ?

The Background : I have two new Avaya ERS 3500 Series Switches and I tried to query/poll Switch 1
with my NetXMS Server but at first the result was poor because the correct MIB's were missing.
I could see just one unknown interface.

Avaya Support has supplied the MIBS and with the help of the guide in the Wiki I could compile them
successfully.

Then I added Switch 2 (SNMP config identical) and I could see all ports, all the topology info and
so on which is really perfect for me.

But : Polling Switch 1 still fails, I see a unknown Interface only and I get polling errors.
Tried to delete Switch 1 from the configuration and restarted the server services and added it
again as a Node which was not successful. Still have polling errors.

Here's a guess : On re-adding as a Node NetXMS has referred to old info about Switch one so
is there a proper to delete the information about this device from the NetXMS Database ?

I am running NetXMS on a Win 20012 R2 Server on PostGRE SQL

Thank you in advance
