Example Concept: SNMP is a protocol used to collect and organize information about managed devices on IP networks, and to modify that information to change device behavior. It operates by polling devices for performance data, such as CPU load or interface statistics. NetFlow, developed by Cisco, is a network protocol that collects IP traffic information as it enters or exits an interface. It provides detailed data about traffic flows, including source and destination IP addresses, ports, and protocols, which is useful for analyzing bandwidth usage and identifying traffic patterns.
