Closed loop control for fixing network configuration issues to aid in device classification

An apparatus, comprising:

• one or more network interfaces to communicate with a network;
• a processor coupled to the network interfaces and configured to execute one or more processes;
• and
• a memory configured to store a process executable by the processor, the process when executed configured to:
• receive traffic telemetry data captured by a plurality of networks and used by device classification services in the networks to classify endpoints in the networks with device types;
• form a matrix of traffic characteristics and associated endpoints from the traffic telemetry data;
• determine that one or more entries of the matrix are empty, the one or more empty entries of the matrix corresponding to one or more traffic characteristics that are missing from the traffic telemetry data for one or more endpoints of a particular network;
• identify a networking entity in the particular network that is common to the one or more endpoints for which the one or more traffic characteristics are missing;
• determine a configuration change for the networking entity by comparing a current configuration of the networking entity to those of one or more networking entities in the other networks;
• and
• initiate implementation of the determined configuration change for the networking entity in the particular network.

A tangible, non-transitory, computer-readable medium storing program instructions that cause a device to execute a process comprising:

• receiving, at the device, traffic telemetry data captured by a plurality of networks and used by device classification services in the networks to classify endpoints in the networks with device types;
• forming, by the device, a matrix of traffic characteristics and associated endpoints from the traffic telemetry data;
• determining, by the device, that one or more entries of the matrix are empty, the one or more empty entries of the matrix corresponding to one or more traffic characteristics that are missing from the traffic telemetry data for one or more endpoints of a particular network;
• identifying, by the device, a networking entity in the particular network that is common to the one or more endpoints for which the one or more traffic characteristics are missing;
• determining, by the device, a configuration change for the networking entity by comparing a current configuration of the networking entity to those of one or more networking entities in the other networks;
• and
• initiating, by the device, implementation of the determined configuration change for the networking entity in the particular network.
