It works

you can create script DCI that will collect all necessary information into table. For example, create script in script library:

table = new Table();
table->addColumn("Node", DCI::STRING, "Node", true);
table->addColumn("Interface", DCI::STRING, "Interface", true);
table->addColumn("Speed", DCI::INT32, "Speed");

for(n : GetAllNodes())
{
   if (!n->isSNMP)
      continue;
   for(i : n->interfaces)
   {
   	row = table->addRow();
   	table->set(row, 0, n->name);
   	table->set(row, 1, i->name);
   	table->set(row, 2, i->speed);
   }
}

return table;

Then create table DCI on any node (I usually use node representing NetXMS server itself) with origin "Script". and set script name as parameter name. Value of this table DCI will contain list of all interfaces on all SNMP capable nodes with their speeds. By changing script you can add more columns and change conditions for inclusion as needed.

So it means that your nodes need to have DCIs with corresponding parameters, e.g. .1.3.6.1.2.1.31.1.1.1.15.1

Does all your equipment has only one network interface? Are OIDs same for all nodes? Or there could be several interfaces on a node? Which should be in the summary table then?
