Description: Extends standard interface management with Riverstone-specific counters and physical port configuration.

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 RIVERSTONE-IF-MIB?

This is a Riverstone Networks proprietary MIB that extends the standard IETF IF-MIB with vendor-specific interface counters and physical port configuration for Riverstone routers/switches. It adds statistics such as capability flags, queueing policy, MRU, Ethernet-II forcing state, cumulative up/down time, transition counts, correlated Layer 1 errors, and bridged octet counts, layered on top of the standard interface table. Its monitoring focus is squarely on interface hardware/link health: tracking how long an interface has been up versus down (rsIfTotalUpTime/rsIfTotalDownTime), how often it has flapped (rsIfUpTransitions/rsIfDownTransitions), and whether physical-layer errors are occurring (rsIfInCorrelatedLayer1Errors), which together reveal flaky cabling, transceiver problems, or unstable links. It explicitly extends the standard IF-MIB and is meant to be used alongside it rather than independently. It is deployed on Riverstone Networks routers and switches in enterprise and service-provider networks. Engineers can download the RIVERSTONE-IF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in RIVERSTONE-IF-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

Riverstone Networks router/switch

Monitoring Examples

An administrator would poll rsIfUpTransitions and rsIfDownTransitions together with rsIfTotalDownTime to detect an interface that is flapping repeatedly, and check rsIfInCorrelatedLayer1Errors to confirm the flapping correlates with physical-layer errors rather than a configuration change. The rsIfStatsTable/rsIfStatsEntry rows provide the per-interface capability and MRU/queue-policy context needed to interpret those counters. A steadily climbing rsIfInBridgedOctets count alongside stable uptime would instead confirm normal bridged traffic growth rather than a fault.

What Can Be Monitored

interface total up/down time
interface up/down transition counts
correlated Layer 1 errors
interface MRU and queue policy
bridged octet counts
Ethernet-II forcing state

How to Use in IPNetwork Monitor

Example using rsIfTotalUpTime OID:

Select a Riverstone Networks router/switch (extended interface uptime/flap/Layer-1 error counters) 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 rsIfTotalUpTime 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 amount of time since the router boots up for which the interface is up. 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 value is unexpectedly low (e.g. under 10 minutes), since that indicates a recent, possibly unplanned, reboot or restart. Click Finish to create the monitor; you can adjust any parameter later.

OIDs

OID symbolic	OID numeric	Type	Access	Description
rsIfCompliance	1.3.6.1.4.1.5567.2.60.2.1.1			The compliance statement for RIVERSTONE-STATS-MIB.
rsIfCompliances	1.3.6.1.4.1.5567.2.60.2.1
rsIfConformance	1.3.6.1.4.1.5567.2.60.2
C32 rsIfDownTransitions	1.3.6.1.4.1.5567.2.60.1.1.1.8	Counter32	read-only	The number of times this interface has changed from link-up to link-down.
T/F rsIfForceEtherIIState	1.3.6.1.4.1.5567.2.60.1.1.1.4	TruthValue	read-only	The object indicates if the port is configured to force input encapsulation to be interpreted as 'Ethernet II'. If the value is false, this means the port is not an Ethernet port or the Ethernet port is not forcing this input encapsulation. On the RS platform, the user can check for the line 'port set input-encapsulation forced-ethernet_ii' in config mode.
BIT rsIfGaugeCapability	1.3.6.1.4.1.5567.2.60.1.2.1.1	Bits	read-only	The validity of each object in this table. Each bit refers to one object. This object indicates if each counter in the row is supported.
rsIfGaugeEntry	1.3.6.1.4.1.5567.2.60.1.2.1		not-accessible	This row contains gauges for a port interface. The number of updates done to caluculate the difference of a gauge in the one minute interval may vary across different software versions. If the updates are infrequent for example every 30 seconds, the user would observe a constant value for that 30 seconds. Discontinuities in the values of this row can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
rsIfGaugeGroup	1.3.6.1.4.1.5567.2.60.2.2.2			The collection of objects representing port interface gauges.
rsIfGaugeTable	1.3.6.1.4.1.5567.2.60.1.2		not-accessible	This table contains gauges for a port interface.
rsIfGroups	1.3.6.1.4.1.5567.2.60.2.2
C64 rsIfInBridgedOctets	1.3.6.1.4.1.5567.2.60.1.1.1.10	Counter64	read-only	The number of bridged octets that are received by this interface. The sum of rsIfInBridgedOctets and rsIfInRoutedOctets is equal to ifInOctets. This object is similar to dot1dTpHCPortInFrames, but bytes are counted instead of frames.
C32 rsIfInCorrelatedLayer1Errors	1.3.6.1.4.1.5567.2.60.1.1.1.9	Counter32	read-only	The number of frames in error due to physical signal degradation. This counter is a close approximation of the actual number of frames dropped due to layer 1 errors. An empirical experiment was done to correlate the registers to the actual frames dropped in a controlled environment that simulates physical signal degradation. On the RS platform, a number of hardware registers were identified that approximate the actual number of frames dropped. The registers would be different for the different interfaces on the RS platform. Usually on WAN interface, this counter is not supported. Refer to the value of rsIfStatsCapability to determine if this interface supports this counter.
C32 rsIfInInvalidMacEncap	1.3.6.1.4.1.5567.2.60.1.1.1.17	Counter32	read-only	The number of frames received by this interface that used invalid MAC encapsulation.

As a result, this packet goes to the CPU to create a L3 flow entry. On the RS platform with HRT mode enabled, the packet would not go to the CPU.
C64 rsIfInL2TableMisses	1.3.6.1.4.1.5567.2.60.1.1.1.12	Counter64	read-only	The number of times that there is no entry in the Forwarding Database. As a result, this frame would go to a CPU.
C64 rsIfInLocalFrames	1.3.6.1.4.1.5567.2.60.1.1.1.11	Counter64	read-only	The number of frames whose destination address is a local MAC address and whose etype is of L2 variety.

C64 rsIfInRoutedCpuPackets	1.3.6.1.4.1.5567.2.60.1.1.1.15	Counter64	read-only	The number of IP packets sent to the CPU. This counter would increase when a packet is destined to the CPU and the L3 table has its flow entry.
C64 rsIfInRoutedOctets	1.3.6.1.4.1.5567.2.60.1.1.1.13	Counter64	read-only	The number of routed octets received by this interface. The sum of rsIfInBridgedOctets and rsIfInRoutedOctets is equal to ifInOctets.
