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 Wellfleet-INT-SERV-MIB?

This is a vendor-specific proprietary MIB from Wellfleet Communications (later Bay Networks/Nortel) managing Integrated Services (IntServ) quality-of-service features, including RSVP-signaled bandwidth reservations and flow admission control. It exposes objects describing active reservations, per-flow admission decisions, and allocated QoS bandwidth. It supports software status monitoring because a flow that is rejected by admission control, or a reservation that fails to establish, directly indicates that a QoS-sensitive application (such as legacy voice or video) will experience degraded service on that router. It conceptually parallels the IETF Integrated Services/RSVP MIBs (RFC 2213/2214) though implemented as a Wellfleet-proprietary equivalent. It is typically deployed on Wellfleet/Bay Networks routers carrying QoS-sensitive traffic that requires RSVP-based bandwidth reservation across a WAN core. Engineers can download the Wellfleet-INT-SERV-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Wellfleet-INT-SERV-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

Wellfleet/Bay Networks routers configured for Integrated Services QoS/RSVP

Monitoring Examples

No sample_objects were provided for this module; based on the short_desc, an operator would poll the RSVP reservation table for active flow entries and the corresponding admission-control decision per flow. A rising count of rejected/denied admission attempts would indicate the reserved bandwidth pool on that interface is exhausted, degrading QoS for new voice or video flows.

What Can Be Monitored

active RSVP reservation count
flow admission control decision
reserved QoS bandwidth per flow

OIDs

OID symbolic	OID numeric	Type	Access	Description
INT wfFlowspecSt2V3AccdDelayVariance	1.3.6.1.4.1.18.3.5.16.3.1.1.15	INTEGER	read-only	AccdDelayVariance is also modified by each intervening ST agent as a measure, in milliseconds squared, of the packet dispersion. This quantity can be used by the target or origin in determining whether the resulting stream has an adequate quality of service to support the application. Note that it is implicitly assumed that the requested delay variance is zero and there is no limit on the delay variance, so there are no parameters to specify these explicitly.
INT wfFlowspecSt2V3AccdMeanDelay	1.3.6.1.4.1.18.3.5.16.3.1.1.14	INTEGER	read-only	AccdMeanDelay is modified by each intervening ST agent. This provides a means of reporting the total expected delay, in milliseconds, for a data packet. Note that it is implicitly assumed that the requested mean delay is zero and there is no limit on the mean delay, so there are no parameters to specify these explicitly.
INT wfFlowspecSt2V3DesPDUBytes	1.3.6.1.4.1.18.3.5.16.3.1.1.16	INTEGER	read-only	DesPDUBytes is the desired PDU size in bytes. This is not necessarily the same as the minimum necessary PDU size. This value may be made smaller by intervening ST agents so long as it is not made smaller than LimitOnPDUBytes. The PDUBytes limits measure the size of the PDUs of next-higher protocol layer, i.e., the user information contained in a data packet. An ST agent must account for both the ST Header (including possible IP encapsulation) and any local network headers and trailers when comparing a network's MTU with PDUBytes. In an ACCEPT message, the value of this field will be no larger than the MTU of the path to the specified target.
INT wfFlowspecSt2V3DesPDURate	1.3.6.1.4.1.18.3.5.16.3.1.1.17	INTEGER	read-only	DesPDURate is the requested PDU rate, expressed as tenths of a packet per second. This value may be made smaller by intervening ST agents so long as it is not made smaller than LimitOnPDURate.
INT wfFlowspecSt2V3DutyFactor	1.3.6.1.4.1.18.3.5.16.3.1.1.3	INTEGER	read-only	DutyFactor is the estimated proportion of the time that the requested bandwidth will actually be in use. Zero is taken to represent 256 and signify a duty factor of 1. Other values are to be divided by 256 to yield the duty factor.
wfFlowspecSt2V3Entry	1.3.6.1.4.1.18.3.5.16.3.1.1		not-accessible
INT wfFlowspecSt2V3ErrorRate	1.3.6.1.4.1.18.3.5.16.3.1.1.4	INTEGER	read-only	ErrorRate expresses the error rate as the negative exponent of 10 in the error rate. One (1) represents a bit error rate of 0.1 and 10 represents 0.0000000001.
INT wfFlowspecSt2V3Index	1.3.6.1.4.1.18.3.5.16.3.1.1.1	INTEGER	read-only	flowspec index
INT wfFlowspecSt2V3LimitOnCost	1.3.6.1.4.1.18.3.5.16.3.1.1.9	INTEGER	read-only	LimitOnCost specifies the maximum cost that the origin is willing to expend. A value of zero indicates that the application is not willing to incur any direct charges for the resources used by the stream. The meaning of non-zero values is left for further study.
INT wfFlowspecSt2V3LimitOnDelay	1.3.6.1.4.1.18.3.5.16.3.1.1.10	INTEGER	read-only	LimitOnDelay specifies the maximum end-to-end delay, in milliseconds, that can be tolerated by the origin.
INT wfFlowspecSt2V3LimitOnPDUBytes	1.3.6.1.4.1.18.3.5.16.3.1.1.11	INTEGER	read-only	LimitOnPDUBytes is the smallest packet size, in terms of ST-user data bytes, that can be tolerated by the origin.
INT wfFlowspecSt2V3LimitOnPDURate	1.3.6.1.4.1.18.3.5.16.3.1.1.12	INTEGER	read-only	LimitOnPDURate is the lowest packet rate that can be tolerated by the origin, expressed as tenths of a packet per second.
INT wfFlowspecSt2V3MinBytesXRate	1.3.6.1.4.1.18.3.5.16.3.1.1.13	INTEGER	read-only	MinBytesXRate is the minimum bandwidth that can be tolerated by the origin, expressed as a product of bytes and tenths of a packet per second.
INT wfFlowspecSt2V3Precedence	1.3.6.1.4.1.18.3.5.16.3.1.1.5	INTEGER	read-only	Precedence is the precedence of the connection being established. Zero represents the lowest precedence. Note that non-zero values of this parameter should be subject to authentication and authorization checks, which are not specified here. In general, the distinction between precedence and priority is that precedence specifies streams that are permitted to take previously committed resources from another stream, while priority identifies those PDUs that a stream is most willing to have dropped when the stream exceeds its guaranteed limits.
INT wfFlowspecSt2V3RecoveryTimeout	1.3.6.1.4.1.18.3.5.16.3.1.1.8	INTEGER	read-only	RecoveryTimeout specifies the nominal number of milliseconds that the application is willing to wait for a failed system component to be detected and any corrective action to be taken.
INT wfFlowspecSt2V3Reliability	1.3.6.1.4.1.18.3.5.16.3.1.1.6	INTEGER	read-only	Reliability is modified by each intervening ST agent as a measure of the probability that a given offered data packet will be forwarded and not dropped. Zero is taken to represent 256 and signify a probability of 1. Other values are to be divided by 256 to yield the probability.
wfFlowspecSt2V3Table	1.3.6.1.4.1.18.3.5.16.3.1		not-accessible	This is the ST-2 version 3 flowspec. The FlowSpec is used to convey stream service requirements end-to-end. We expect that other versions of FlowSpec will be needed in the future, which may or may not be subsets or supersets of the version described here. PBytes will allow new constraints to be added to the end without having to simultaneously update all implementations in the field. Implementations are expected to be able to process in a graceful manner a Version 4 (or higher) structure that has more elements than shown here.
INT wfFlowspecSt2V3Tradeoffs	1.3.6.1.4.1.18.3.5.16.3.1.1.7	INTEGER	read-only	Tradeoffs is incompletely defined at this time. Bits currently specified are as follows: The most significant bit in the field, bit 0 in the Figure 24, when one (1) means that each ST agent must 'implement' all constraints in the FlowSpec even if they are not shown in the figure, e.g., when the FlowSpec has been extended. When zero (0), unknown constraints may be ignored. The second most significant bit in the field, bit 1, when one (1) means that one or more constraints are unknown and have been ignored. When zero (0), all constraints are known and have been processed. The third most significant bit in the field, bit 2, is used for RevChrg; see Section 3.6.5 (page 46). Other bits are currently unspecified, and should be set to zero (0) by the origin ST agent and not changed by other agents unless those agents know their meaning.
INT wfFlowspecSt2V3Version	1.3.6.1.4.1.18.3.5.16.3.1.1.2	INTEGER	read-only	Version identifies the version of the FlowSpec. Version 3 is defined here.
INT wfIntSrvIfFlowCct	1.3.6.1.4.1.18.3.5.16.4.1.1.10	INTEGER	read-only	The circuit number of this IntSrv interface
IP wfIntSrvIfFlowDestination	1.3.6.1.4.1.18.3.5.16.4.1.1.1	IpAddress	read-only	The IP Address used as a destination address for all senders in this flow.
INT wfIntSrvIfFlowDestinationPort	1.3.6.1.4.1.18.3.5.16.4.1.1.3	INTEGER	read-only	The UDP or TCP port number used as a destina- tion port for all senders in this flow. A value of zero indicates that the IP protocol in use, specified by wfIntSrvIfFlowDestinationProtocol, does not use ports.
INT wfIntSrvIfFlowDestinationProtocol	1.3.6.1.4.1.18.3.5.16.4.1.1.2	INTEGER	read-only	The value of the IP Protocol field in this flow, typically UDP or TCP.
wfIntSrvIfFlowEntry	1.3.6.1.4.1.18.3.5.16.4.1.1		not-accessible	Information describing the use of a given in- terface by a given flow.
wfIntSrvIfFlowGroup	1.3.6.1.4.1.18.3.5.16.4
INT wfIntSrvIfFlowMin	1.3.6.1.4.1.18.3.5.16.4.1.1.9	INTEGER	read-only	The minimum message size for this flow. The policing algorithm will treat smaller messages as though they are this size.
INT wfIntSrvIfFlowQueue	1.3.6.1.4.1.18.3.5.16.4.1.1.8	INTEGER	read-only	The number of the queue used by this traffic. Note that the interpretation of this object is implementation-specific, as implementations vary in their use of queue identifiers.
INT wfIntSrvIfFlowRate	1.3.6.1.4.1.18.3.5.16.4.1.1.6	INTEGER	read-only	The Average Bit Rate of the sender's data stream, in Kilobits. The rate may be arbi- trarily fast during a short interval such as the duration of a video frame. However, over any two such intervals it will not average fas- ter than the average rate as transmitted by the sender.
IP wfIntSrvIfFlowSource	1.3.6.1.4.1.18.3.5.16.4.1.1.4	IpAddress	read-only	The IP Address used as a source address by this sender in this flow. If zero, all senders are included in the flow.
INT wfIntSrvIfFlowSourcePort	1.3.6.1.4.1.18.3.5.16.4.1.1.5	INTEGER	read-only	The UDP or TCP port number used as a source port by this sender in this flow. A value of zero indicates that the IP protocol in use, specified by wfIntSrvIfFlowDestinationProtocol, does not use ports, or (when wfIntSrvIfFlowDestinationPort is non-zero) that data from all senders is in- cluded in this class of flows.
wfIntSrvIfFlowTable	1.3.6.1.4.1.18.3.5.16.4.1		not-accessible	Information describing the reserved flows us- ing the system's interfaces.
INT wfIntSrvIfFlowWeight	1.3.6.1.4.1.18.3.5.16.4.1.1.7	INTEGER	read-only	The weight used to prioritize the traffic. Note that the interpretation of this object is implementation-specific, as implementations vary in their use of weighting procedures.
wfReservationsFlowspecGroup	1.3.6.1.4.1.18.3.5.16.3
wfReservationsResourcesGroup	1.3.6.1.4.1.18.3.5.16.2
INT wfTxLineRscCfgBandwidthInterval	1.3.6.1.4.1.18.3.5.16.2.1.3.1.7	INTEGER	read-write	Interval over which bandwidth is measured, in seconds. Default is ten seconds.
INT wfTxLineRscCfgDelete	1.3.6.1.4.1.18.3.5.16.2.1.3.1.1	INTEGER	read-write	Creation and deletion flag for this record
wfTxLineRscCfgEntry	1.3.6.1.4.1.18.3.5.16.2.1.3.1		not-accessible
INT wfTxLineRscCfgEstBandwidth	1.3.6.1.4.1.18.3.5.16.2.1.3.1.3	INTEGER	read-write	Estimated usable bandwidth by this router in bits per second.
INT wfTxLineRscCfgInflateReservations	1.3.6.1.4.1.18.3.5.16.2.1.3.1.8	INTEGER	read-write	Any reservation made on this line will be inflated by this percentage.
INT wfTxLineRscCfgLargestBandwidth	1.3.6.1.4.1.18.3.5.16.2.1.3.1.14	INTEGER	read-write	The maximum bandwidth that a single flow can reserve on this line. [ 0 (zero) implies no maximum.]
INT wfTxLineRscCfgLargestBuffer	1.3.6.1.4.1.18.3.5.16.2.1.3.1.15	INTEGER	read-write	The maximum buffer space that a single flow can reserve on this line. [ 0 (zero) implies no maximum.]
INT wfTxLineRscCfgLineNumber	1.3.6.1.4.1.18.3.5.16.2.1.3.1.2	INTEGER	read-only	Line number
INT wfTxLineRscCfgMultiLineSelectAlgorithm	1.3.6.1.4.1.18.3.5.16.2.1.3.1.11	INTEGER	read-write	This algorithm influences how the circuit resource manager will select which line will be used for a new resource request. first (1) does a first-fit. round (2) does a round-robin. If first-fit is selected and the ThresholdBandwidth parameter is non-zero, a first-fit algorithm is done until a line reaches its threshold. The algorithm then moves to the the next line. Once all lines are at their threshold, the algorithm is simply first-fit. All lines for a circuit should select the same algorithm. If any one specifies first-fit, first-fit will be used.
INT wfTxLineRscCfgMultiLineThresholdBandwidth	1.3.6.1.4.1.18.3.5.16.2.1.3.1.12	INTEGER	read-write	If the multi-line selection algorithm is threshold, this is the threshold value for this line. It must be less than the reservable bandwidth value.
INT wfTxLineRscCfgResvBandwidth	1.3.6.1.4.1.18.3.5.16.2.1.3.1.4	INTEGER	read-write	Reservable bandwidth on this line.
INT wfTxLineRscCfgResvLatency	1.3.6.1.4.1.18.3.5.16.2.1.3.1.13	INTEGER	read-write	The maximum latency acceptable for a reserved flow packet. This parameter limits the amount of unreserved data that the link scheduler can put onto the driver transmit ring. When the data on the transmit ring reaches a size where additional unreserved data would take longer than the value of this parameter to clock out, no more data will be enqueued. Reduce this parameter to obtain better delay characteristics for reserved flows, but note that this will result in somewhat reduced overall throughput. Units are milliseconds.
INT wfTxLineRscCfgResvPolicingAlgorithm	1.3.6.1.4.1.18.3.5.16.2.1.3.1.6	INTEGER	read-write	reserved-traffic policing algorithm: none - no policing lbucket - leaky bucket policing
INT wfTxLineRscCfgResvTrafficAlgorithm	1.3.6.1.4.1.18.3.5.16.2.1.3.1.5	INTEGER	read-write	reserved-traffic queueing algorithm: none - schedule as best-effort priority - schedule ahead of best-effort
wfTxLineRscCfgTable	1.3.6.1.4.1.18.3.5.16.2.1.3		not-accessible	This table contains resource reservation configuration information on a per-line basis for outbound traffic.
INT wfTxLineRscCfgUnreservedPolicingAlgorithm	1.3.6.1.4.1.18.3.5.16.2.1.3.1.9	INTEGER	read-write	Policing algorithm for unreserved traffic. qlimit (1) limits the number of buffers (packets) of unreserved traffic that will be queued up. lbucket (2) applies a leaky bucket algorithm based on the bandwidth that is not guaranteed. The leaky bucket algorithm does not allow the unreserved traffic to take advantage of unused reserved bandwidth.
INT wfTxLineRscCfgUnreservedQueueLength	1.3.6.1.4.1.18.3.5.16.2.1.3.1.10	INTEGER	read-write	If the unreserved policing algorithm is qlimit, this is the maximum number of best-effort packets that will be held for transmission. This parameter affects the amount best-effort traffic will be clipped when congestion occurs. Overriden by priority queueing limits, if configured.
