z
To ensure functionality with SNMP, MIB objects must be defined with the proper keywords , as
shown in Table 4 .
Aruba Enterprise MIBs support SNMPv1, SNMPv2, and SNMPv3.
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.
z
Traps are unconfirmed notifications—the receiver does not acknowledge to the sender that the
information was received.
z
Inform requests are confirmed notifications—the receiver acknowledges to the sender that the
information was received.
Following are descriptions of trap types.
z
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.
z
Analog Alarm Inputs
Analog alarms measure characteristics that can affect equipment performance—variable levels of
voltage or current, temperature, humidity, and pressure.
z
Ping Alarms
Ping alarms are used to ping network devices at regular intervals. If a device fails to respond, an
alarm (SNMP trap) will be sent.
z
Control Relays
Relay outputs enable operating remote site equipment.
