Understanding Network Monitoring Data Categories

????Network devices operate across three functional planes:

✅A. Management Plane:

Handlesdevice configuration, authentication, and monitoring.

Example:SNMP, SSH, NETCONF logs.

✅B. Data Plane (Forwarding Plane):

Handlespacket forwarding and switching.

Example:Interface statistics, traffic rates, dropped packets.

✅C. Control Plane:

Handlesrouting, signaling, and protocol operations.

Example:BGP, OSPF, and MPLS signaling messages.

❌D. Monitoring Plane (Incorrect Choice):

There is no "monitoring plane" in network architecture.

Monitoring tools collect data frommanagement, control, and data planes, butdo not form a separate plane.

Why is the Answer D (Monitoring-plane data)?

❌Monitoring-plane does not exist as a separate category in network architecture.

✅O&M tools collect data from management, control, and data planes, but do not define a separate "monitoring plane".

Real-World Application:

Huawei iMaster NCE-Campus & iMaster NCE-WANcollect real-timenetwork statistics and alarms.

Network Performance Monitoring (NPM)toolsanalyze control-plane eventsto detect failures.
