Description

During Layer 2 Discovery, Information collected by a specific SNMP probe has the ability to create multiple CI records in CMDB for every route forwarding rule detected on a networking device.

There maybe scenarios where this behaviour of having unique CI records being created for every forwarding rule might not be desirable and considered as clutter.


Release or Environment

All

Cause

The data on the forwarding table/rules is collected by the probe "SNMP - Switch - ForwardingTable"

This probe returns information from a switch's forwarding table.


Discovery Definition -> Probes -> SNMP - Switch - ForwardingTable

Resolution

In order to stop data to be collected on forwarding rules, and CI's being created we can disable the corresponding sensor reacting to the probe.
