19.19.1 Suppressing the use of discovery protocol collections

To suppress the use of discovery protocol collections, follow these steps:

1. Create the following file:

   • Windows: %NnmDataDir%\shared\nnm\conf\disco\disco.SkipXdpProcessing

   • UNIX: $NnmDataDir/shared/nnm/conf/disco/disco.SkipXdpProcessing

     The disco.SkipXdpProcessing file is case-sensitive.

2. Add to the disco.SkipXdpProcessing file the management address for each device for which protocol collection is to be suppressed.

   For details, see the disco.SkipXdpProcessing Reference Page.

3. Restart the NNMi management server:

   a. Run the ovstop command on the NNMi management server.

   b. Run the ovstart command on the NNMi management server.

   Important note

   Suppressing discovery protocol processing of a node or nodes might cause some inaccuracies in the Layer 2 layout of the managed network.

The ovjboss service reads the disco.SkipXdpProcessing file at startup. If you make any changes after starting NNMi, restart NNMi as shown in this step.

If you ran the set snmp timefilter break command on any Enterasys devices, remove their device addresses from the disco.SkipXdpProcessing file, and then restart NNMi as shown in this step. NNMi opens more accurate Layer 2 maps when it uses discovery protocols.

For details, see the disco.SkipXdpProcessing Reference Page.
