Data dumping on Network Management Systems (NMS) can occur in several types: (A) Periodic dumping, where data is saved at set intervals for monitoring and analysis; (C) Overflow dumping, triggered when buffer capacity is exceeded; and (D) Manual dumping, initiated by user commands. (B) Automatic dumping is not a standard term here or is often encompassed within periodic or overflow dumping mechanisms. HCIP-Transmission references these types as part of NMS data handling and fault diagnosis strategies, enabling efficient network performance management and troubleshooting.
