Snmp VLAN inventory turned off

Hi,

We are using NPM 11.0, we have noticed that newly build VLAN's on Cisco or on some other nodes VLAN info is incomplete, or lacking. This while during the 'list resources' discovery, VLAN has been checked.

I have found a simular, discription of a problem, in the Solarwinds Knowledge Base: Discovery of VLAN interfaces is taking too long. How do I disable VLAN interface discovery?   This is the opposite problem. We want to enable VLAN discovery.

In the NCM settings (via NCM settings -> Node Inventory settings -> Extend VLANs inventory (Note: this process is very slow and not recommended)  has already been enabled.

In the diagnostics file of the poller, I have found this message, that maybe is a root cause of this problem :

VLANSnmpInventoryStep - NotApplicable (000,00s): [Interfaces SNMP Inventory step is turned off.   

After that I have checked the discovery.conf file in the ProgramFiles32/SolarWinds/Orion directory, where discovery had the "True" status....

Does anybody know where I can reenable this Interfaces SNMP Inventory step ?

Thanks!
