Description: Manages interface output queue configuration, scheduling policies, and congestion statistics on Riverstone routers.

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-QUEUE-MIB?

RIVERSTONE-QUEUE-MIB is a Riverstone Networks proprietary MIB for their routing/switching platforms, covering per-port output queue configuration, scheduling/discard policies, and queue traffic statistics used for QoS management. It exposes both configuration objects (queue name, description, discard policy, maximum capacity) and statistics objects (byte counts, last capacity-change time, validity flags) for each queue on each port. Its monitoring value is on performance/software status: detecting when a queue is dropping traffic due to its discard policy being invoked, when queue byte counters show congestion building on a particular class of traffic, or when a queue's capacity was recently changed, which could explain a shift in traffic behavior. It is a self-contained Riverstone vendor MIB with no explicit external dependency evident from the module text, though it follows general QoS/queuing conventions common to router MIBs. It is deployed on Riverstone Networks routers/switches where administrators need visibility into per-port QoS queue behavior and congestion. Engineers can download the RIVERSTONE-QUEUE-MIB file directly to load it into their MIB browser.

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

Riverstone Networks routers/switches

Monitoring Examples

An administrator would poll rsQueuePropertiesTable/rsQueuePropertiesEntry for rsQueueDiscardPolicy and rsQueueMaxCapacity to confirm a queue's configured drop behavior and capacity limit, then cross-reference rsQueueStatsTable/rsQueueStatsEntry for rsQueueBytes to see how much traffic is currently queued. A queue whose rsQueueBytes approaches rsQueueMaxCapacity, combined with rsQueueStatsValid indicating current data, signals imminent tail-drop congestion for that traffic class, while rsQueueStatsLastCapChange reveals if a recent capacity tweak coincides with the congestion onset.

What Can Be Monitored

queue discard policy
queue maximum capacity
queued byte count
last capacity change time
queue statistics validity

How to Use in IPNetwork Monitor

Example using rsQueueBytes OID:

Select a Riverstone Networks routers/switch (per-port QoS output queue configuration/statistics) 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 rsQueueBytes 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 number of bytes that have passed through this priority queue on this port. 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.

OIDs

OID symbolic	OID numeric	Type	Access	Description
rsQueueMIB	1.3.6.1.4.1.5567.2.70			This MIB module represents information on each of the queues for each port.
rsQueueMIBObjects	1.3.6.1.4.1.5567.2.70.1
rsQueuePropertiesTable	1.3.6.1.4.1.5567.2.70.1.1		not-accessible	This table contains descriptions of different queues. It is used as a reference table by rsQueueStatsTable.
rsQueuePropertiesEntry	1.3.6.1.4.1.5567.2.70.1.1.1		not-accessible	This entry represents a queue and its properties. It is indexed by a natural number.
NUM rsQueueId	1.3.6.1.4.1.5567.2.70.1.1.1.1	IndexInteger	not-accessible	An index that enumerates the number of queue entries.
STR rsQueueName	1.3.6.1.4.1.5567.2.70.1.1.1.2	SnmpAdminString	read-only	The name of the queue. For example, on the RS platform, the four queue names are control, high, medium, and low.
STR rsQueueDescr	1.3.6.1.4.1.5567.2.70.1.1.1.3	SnmpAdminString	read-only	A more detailed description of the functionality of the queue.
RSD rsQueueDiscardPolicy	1.3.6.1.4.1.5567.2.70.1.1.1.4	RsDiscardPolicy	read-only	The type of policy used by the queue to drop a frame.
