Description: Monitors chassis environmental conditions including temperature, fan status, and power supply health on Redback SmartEdge BRAS.

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 RBN-ENVMON-MIB?

RBN-ENVMON-MIB is a Redback Networks enterprise MIB that generically manages environmental monitoring functionality across Redback's SmartEdge broadband remote access server (BRAS) platform. It defines two simple status tables -- rbnFanStatusTable and rbnPowerStatusTable -- each indexed by a test-point number rather than a physical assembly, since a single test point can represent the aggregate status of multiple fans or power supplies. Each entry exposes a human-readable rbnFanDescr/rbnPowerDescr and a boolean rbnFanFail/rbnPowerFail flag indicating whether the monitored fan(s) or power supply(ies) covered by that test point have failed. Two accompanying notifications, rbnFanFailChange and rbnPowerFailChange, fire whenever the corresponding failure flag transitions, making this a lightweight but effective early-warning MIB for chassis hardware health rather than a detailed sensor-reading MIB. It is deployed on Redback SmartEdge routers/BRAS chassis and depends on the RBN-SMI enterprise tree for its OID registration, and the RBN-ENVMON-MIB MIB Browser view is typically the fastest way to inspect current fan/power health on these platforms.

IPNetwork Monitor allows you to monitor SNMP objects defined in RBN-ENVMON-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.

Monitoring Examples

An operator polls rbnFanFail and rbnPowerFail across all entries in rbnFanStatusTable and rbnPowerStatusTable to get a quick pass/fail summary of chassis cooling and power, and subscribes to rbnFanFailChange/rbnPowerFailChange traps; a fan or power test point flipping to true(1) would indicate a failed fan assembly or power supply needing replacement before thermal or power redundancy is compromised.

OID symbolic	OID numeric	Type	Access	Description
rbnEnvMonMIB	1.3.6.1.4.1.2352.2.4			The MIB used to genericially manage Environmental Monitor functionality on RedBack Networks devices.
rbnEnvMonMIBNotifications	1.3.6.1.4.1.2352.2.4.0
NTF rbnFanFailChange	1.3.6.1.4.1.2352.2.4.0.1			A rbnFanFailChange notification signifies that the value of an instance of rbnFanFail has changed.
NTF rbnPowerFailChange	1.3.6.1.4.1.2352.2.4.0.2			A rbnPowerFailChange notification signifies that the value of an instance of rbnPowerFail has changed
rbnEnvMonMIBObjects	1.3.6.1.4.1.2352.2.4.1
rbnFanStatusTable	1.3.6.1.4.1.2352.2.4.1.1		not-accessible	This table contains one row per fan test point. Note that there is not necessarily a one-to-one relationship between fan test points and fan assemblies; a single test point may be used to monitor the status of multiple fans.
rbnFanStatusEntry	1.3.6.1.4.1.2352.2.4.1.1.1		not-accessible	Information about a particular fan test point
I32 rbnFanIndex	1.3.6.1.4.1.2352.2.4.1.1.1.1	Integer32	not-accessible	The index of a fan test point.
STR rbnFanDescr	1.3.6.1.4.1.2352.2.4.1.1.1.2	DisplayString	read-only	The description of a fan test point. If an instance of this object is associated with a single fan assembly, then the value of this object should be the same as the name by which the assembly is normally referenced. If an instance is associated with multiple fan assemblies, then the value of this object should contain the names of all of the fan assemblies being monitored.
T/F rbnFanFail	1.3.6.1.4.1.2352.2.4.1.1.1.3	TruthValue	read-only	The status of a fan test point. If an instance of this object has the value true, then a fan monitored by the test point has failed. If an instance of this object has the value false, then the fan (or fans) monitored by the test point are operational.
rbnPowerStatusTable	1.3.6.1.4.1.2352.2.4.1.2		not-accessible	This table contains one row per power test point. Note that there is not necessarily a one-to-one relationship between power test points and power supply assemblies; a single test point may be used to monitor the status of multiple power supplies.
rbnPowerStatusEntry	1.3.6.1.4.1.2352.2.4.1.2.1		not-accessible	Information about a particular power test point
I32 rbnPowerIndex	1.3.6.1.4.1.2352.2.4.1.2.1.1	Integer32	not-accessible	The index of a power test point.
STR rbnPowerDescr	1.3.6.1.4.1.2352.2.4.1.2.1.2	DisplayString	read-only	The description of a power supply test point. If an instance of this object is associated with a single power supply assembly, then the value of this object should be the same as the name by which the assembly is normally referenced. If an instance is associated with multiple power supply assemblies, then the value of this object should contain the names of all of the power supply assemblies being monitored.
T/F rbnPowerFail	1.3.6.1.4.1.2352.2.4.1.2.1.3	TruthValue	read-only	The status of a power test point. If an instance of this object has the value true, then a power supply monitored by the test point has failed. If an instance of this object has the value false, then the power supply (or supplies) monitored by the test point are operational.
