Traps are a mechanism for network devices to send unsolicited notifications of events or alarms to a management system. They can be configured to notify the network management team of specific events, such as the unplugging of a point-to-point link on a core router. This feature allows early detection and possible resolution of issues.
MIB (Management Information Base) is a database of information that describes the management data of a device. OID (Object Identifier) is a unique identifier used to identify managed objects in the MIB.
Baselines are a standard set of measurements used to establish normal network behavior, and they are used to compare current network activity against. Baselines can be used to detect abnormal behavior, but they are not as effective as traps for early detection of specific events.
