1. On the Orion Console, go to Settings > Manage nodes.
2. Find the node, highlight it, and then select edit.
3. Browse to the bottom of the page and untick the box next to Poll Layer 3 data from device.
4. Tick the box next to Disable VRF context polling.

   

Perform the following using SQL commands from the database (NPM 11.5.x only):

1. Find the Nodeid:
   1. Start > All Programs > Solarwinds Orion > Advanced Features > Database Manager > Add Default Server>

      Expand the NPM Database (default) NetPerfmon.

   2. Right-click the database name > Select New Query.
   3. ​Select nodeid from nodesdata where caption name = <NodeCaption>

      Where <Node Caption> is the node caption of the node you want to modify.

2. Disable context polling:
   1. Right-click the database name > Select New Query.
   2. Run the following query: 

      -- Scripts are not supported under any SolarWinds support program or service.

      UPDATE UDT_NODECAPABILITY SET CONTEXTPOLLINGDISABLED=0 where nodeid = '<Nodeid>' 

      where <NodeID> is the node id gathered earlier.
