SNMP not inventory remote network

Question

Dear all,

Hope that someone can help me with this. I can't manage to inventory a remote network with OCS. It just makes a ping and then stops.

SNMPWALK works without problems.

Hi,
maybie SNMP not authorized in other networks i mean switchs, routers.exemple  if you have cisco, it's not enabled by default
try local inventory on one computer who had snmp, and look in generated XML if va SNMP data ? if yes, we can take a look if there is not a problem on server.

Regards

Hello,

thanks for the quick response.

Snmp is working. When i start a snmpwalk this works without problem. The OCS Server and OCS Inventory Client are on the same machine.
