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.
