Description: Monitors Avici Systems router chassis bay occupancy, card insertion events, and per-bay power status.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is AVICI-BAY-MIB?

AVICI-BAY-MIB is a vendor MIB from Avici Systems, a core router manufacturer, for monitoring the physical bay slots of an Avici router chassis. It exposes per-bay status/LED indicators, alarm cut-off control, card insertion/occupancy, and configurable temperature thresholds. This is squarely a hardware-health monitoring MIB: it tracks bay/module temperature against critical, major, and minor thresholds, critical/major/minor alarm LED states, card presence, and alarm/power status, making it central to detecting overheating cards or power/alarm conditions in the chassis. It works alongside Avici's broader chassis/system MIBs, referenced through objects like aviciBayControllerNotifications, for full system alarm correlation. It is deployed on Avici core routers in carrier backbone environments where continuous bay-level temperature and alarm monitoring is critical to avoid hardware damage. Engineers can download the AVICI-BAY-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in AVICI-BAY-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

Avici Systems core routers (chassis bay/module hardware)

Monitoring Examples

An admin would poll aviciBayTable rows keyed by aviciBayIndex, comparing the current bay temperature against aviciBayTempCriticalThreshold/aviciBayTempMajorThreshold/aviciBayTempMinorThreshold to catch overheating cards, and checking aviciBayCriticalLed/aviciBayMajorLed/aviciBayMinorLed for active alarm indicators. A bay temperature crossing aviciBayModTempCriticalThreshold accompanied by an aviciBayCriticalLed alarm and an aviciBayNotifications trap would signal an overheating module requiring immediate attention or an aviciBayAlarmCutOff action.

What Can Be Monitored

bay temperature
bay/module temperature thresholds
bay alarm LED status (critical/major/minor)
card occupancy per bay
alarm cut-off state

How to Use in IPNetwork Monitor

Example using aviciBaySlotRxOctets OID:

Select an Avici Systems core/backbone router (legacy) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type aviciBaySlotRxOctets into the Find box to locate it in the OID tree, selecting the specific row/instance you want to monitor since this is a table column, then select it and click OK. The total number of slot octets received. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.

NTF aviciBayFanNotification	1.3.6.1.4.1.2474.1.4.2.0.2			A Fan notification is sent when the specified fan detects a fault or clears a fault. The current ambient air temperature entering the fan is reported in the aviciBayFanCurrTemp object. All existing fan faults are reported in the aviciBayFanCurrFailures object as a bitmap. If no failures exist, this object contains a 0. A human readable description of the event triggering this notification is included in the aviciSysTrapDescr object. Communication Failure: This failure indicates that the cooling module has been removed or the cooling module firmware is no longer communicating with the bay controller. If a communication failure occurs, the fans will run in autonomous mode until communication with the bay controller is reestablished. Once communication is established, the failure is cleared. General Failure: This failure indicates that the cooling module firmware is able to communicate with the bay controller and is reporting a broken fan. This could mean that the fan is burned out, jammed, or the firmware is unable to sense fan speed due to tachometer failure. When the problem is corrected, the failure is cleared. Filter Blocked: This failure indicates that the fan detected that the filter is blocked. When the obstruction is removed from the filter or the clogged air filter is replaced, this failure will clear. Bad or absent internal thermistor: This failure indicates that the fan internal thermistor is missing or is not functioning. If the thermister is not functioning, the fan cannot sense the incoming ambient air temperature. The ambient temperature is used to control fan speed in autonomous mode and when there are no modules reporting their current temperature. Bad or absent external thermistor: This failure indicates that the fan external thermistor is expected to be installed and is not functioning. Minor temperature threshold: This failure indicates that the incoming ambient air temperature is above the minor threshold temperature, but below the major threshold temperature. Either the cooling system in the building has failed, or it has insufficient cooling capacity for the equipment in the room. A rapid rise in temperature usually indicates cooling system failure whereas a slow rise usually indicates insufficient cooling capacity. When the temperature drops below the minor threshold, this failure will clear. Major temperature threshold: This failure indicates that the incoming ambient air temperature is above the major threshold temperature, but below the critical threshold temperature. Either the cooling system in the building has failed, or it has insufficient cooling capacity for the equipment in the room. A rapid rise in temperature usually indicates cooling system failure whereas a slow rise usually indicates insufficient cooling capacity. When the temperature drops below the major threshold, this failure will clear. Critical temperature threshold: This failure indicates that the incoming ambient air temperature is above the critical threshold temperature. Either the cooling system in the building has failed, or it has insufficient cooling capacity for the equipment in the room. A rapid rise in temperature usually indicates cooling system failure whereas a slow rise usually indicates insufficient cooling capacity. When the temperature drops below the critical threshold, this failure will clear.
