embedded in the controller firmware, unlike some devices such as servers that require the agent to be installed separately. MIBs are used for communication between the Managers and the Agents. The OIDs of the MIBs enable the Managers and Agents to communicate specific data requests and data returns. To ensure functionality with SNMP, MIB objects must be defined with the proper keywords, as shown in Table 6. ArubaOS Enterprise MIBs support SNMPv1, SNMPv2, and SNMPv3.

NO Traps An event is a change on a network device, such as a change in value that crosses threshold. Some events are categorized as alarms, other events only provide information. When an event occurs on a network device, SNMP notifications are sent out as traps or information requests. Traps are unconfirmed notifications-the receiver does not acknowledge to the sender that the information was received. Inform requests are confirmed notifications-the receiver acknowledges to the sender that the information was received. Following are descriptions of trap types. Discrete Alarm Inputs These traps, also known as digital inputs or contact closures, are used for monitoring equipment failures, intrusion alarms, beacons, and flood and fire detectors. Analog Alarm Inputs Analog alarms measure characteristics that can affect equipment performance-variable levels of voltage or current, temperature, humidity, and pressure.
