Description: Defines managed objects for the Integrated Services model, covering interface attributes and resource allocation by reservation protocols such as RSVP.

IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring INTEGRATED-SERVICES-MIB with a free 30-day trial of IPNetwork Monitor.

What Is INTEGRATED-SERVICES-MIB?

INTEGRATED-SERVICES-MIB is an IETF standards-track MIB describing the Integrated Services (IntServ) architecture, covering interface-level QoS attributes and resource reservations established by protocols such as RSVP. Its data categories are configuration and state for per-interface service classes and reservation flows rather than hardware environment. It supports monitoring of software/service status by exposing whether interfaces have IntServ enabled and what reservation state exists, useful for confirming QoS policy is actually in effect rather than checking physical health. It is explicitly dependent on RSVP and the broader IntServ framework (RFC 2211/2212 service definitions) it was written to support. Deployment context is routers and QoS-capable network devices in networks using RSVP-signaled bandwidth reservations for real-time traffic, and this INTEGRATED-SERVICES-MIB reference remains the standard citation for engineers implementing IntServ instrumentation on such devices.

IPNetwork Monitor allows you to monitor SNMP objects defined in INTEGRATED-SERVICES-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

vendor-neutral, standards-based MIB, not tied to a specific manufacturer
router or QoS-capable network device supporting RSVP/IntServ

Monitoring Examples

An operator would examine objects under intSrvGenObjects to determine which interfaces have Integrated Services enabled and what general resource parameters apply, then check intSrvObjects for active reservation-related state to confirm RSVP-signaled flows are being honored. Because much of this module's substance is in general/interface objects rather than large per-flow tables (per the grouped conformance structure intSrvGroups/intSrvCompliances), the specific per-reservation table names are not enumerated among the sample objects provided.

What Can Be Monitored

per-interface IntServ enablement
RSVP reservation state

OIDs

OID symbolic	OID numeric	Type	Access	Description
intSrv	1.3.6.1.2.1.52			The MIB module to describe the Integrated Services Protocol
intSrvCompliance	1.3.6.1.2.1.52.4.2.1			The compliance statement
intSrvCompliances	1.3.6.1.2.1.52.4.2
intSrvConformance	1.3.6.1.2.1.52.4
C32 intSrvFlowBestEffort	1.3.6.1.2.1.52.1.2.1.20	Counter32	read-only	The number of packets that were remanded to best effort service.
BUR intSrvFlowBurst	1.3.6.1.2.1.52.1.2.1.15	BurstSize	read-create	The size of the largest burst expected from the sender at a time. If this is less than the sender's advertised burst size, the receiver is asking the network to provide flow pacing beyond what would be provided under normal circumstances. Such pac- ing is at the network's option.
OCT intSrvFlowDestAddr	1.3.6.1.2.1.52.1.2.1.4	OCTET STRING	read-create	The destination address used by all senders in this session. This object may not be changed when the value of the RowStatus object is 'ac- tive'.
INT intSrvFlowDestAddrLength	1.3.6.1.2.1.52.1.2.1.6	INTEGER	read-create	The length of the destination address in bits. This is the CIDR Prefix Length, which for IP4 hosts and multicast addresses is 32 bits. This object may not be changed when the value of the RowStatus object is 'active'.
POR intSrvFlowDestPort	1.3.6.1.2.1.52.1.2.1.9	Port	read-create	The UDP or TCP port number used as a destina- tion port for all senders in this session. If the IP protocol in use, specified by intSrvResvFwdProtocol, is 50 (ESP) or 51 (AH), this represents a virtual destination port number. A value of zero indicates that the IP protocol in use does not have ports. This ob- ject may not be changed when the value of the RowStatus object is 'active'.
T/F intSrvFlowDiscard	1.3.6.1.2.1.52.1.2.1.22	TruthValue	read-create	If 'true', the flow is to incur loss when traffic is policed. If 'false', policed traff- ic is treated as best effort traffic.
intSrvFlowEntry	1.3.6.1.2.1.52.1.2.1		not-accessible	Information describing the use of a given in- terface by a given flow. The counter intSrvFlowPoliced starts counting at the in- stallation of the flow.
INT intSrvFlowFlowId	1.3.6.1.2.1.52.1.2.1.11	INTEGER	read-only	The flow ID that this sender is using, if this is an IPv6 session.
OCT intSrvFlowIfAddr	1.3.6.1.2.1.52.1.2.1.13	OCTET STRING	read-create	The IP Address on the ifEntry on which this reservation exists. This is present primarily to support those interfaces which layer multi- ple IP Addresses on the interface.
NUM intSrvFlowInterface	1.3.6.1.2.1.52.1.2.1.12	InterfaceIndex	read-create	The ifIndex value of the interface on which this reservation exists.
MES intSrvFlowMaxTU	1.3.6.1.2.1.52.1.2.1.19	MessageSize	read-create	The maximum datagram size for this flow that will conform to the traffic specification. This value cannot exceed the MTU of the interface.
MES intSrvFlowMinTU	1.3.6.1.2.1.52.1.2.1.18	MessageSize	read-create	The minimum message size for this flow. The policing algorithm will treat smaller messages as though they are this size.
TES intSrvFlowNewIndex	1.3.6.1.2.1.52.2.1	TestAndIncr	read-write	This object is used to assign values to intSrvFlowNumber as described in 'Textual Con- ventions for SNMPv2'. The network manager reads the object, and then writes the value back in the SET that creates a new instance of intSrvFlowEntry. If the SET fails with the code 'inconsistentValue', then the process must be repeated; If the SET succeeds, then the ob- ject is incremented, and the new instance is created according to the manager's directions.
SES intSrvFlowNumber	1.3.6.1.2.1.52.1.2.1.1	SessionNumber	not-accessible	The number of this flow. This is for SNMP In- dexing purposes only and has no relation to any protocol value.
INT intSrvFlowOrder	1.3.6.1.2.1.52.1.2.1.24	INTEGER	read-create	In the event of ambiguity, the order in which the classifier should make its comparisons. The row with intSrvFlowOrder=0 is tried first, and comparisons proceed in the order of in- creasing value. Non-serial implementations of the classifier should emulate this behavior.
INT intSrvFlowOwner	1.3.6.1.2.1.52.1.2.1.3	INTEGER	read-create	The process that installed this flow in the queue policy database.
C32 intSrvFlowPoliced	1.3.6.1.2.1.52.1.2.1.21	Counter32	read-only	The number of packets policed since the incep- tion of the flow's service.
POR intSrvFlowPort	1.3.6.1.2.1.52.1.2.1.10	Port	read-create	The UDP or TCP port number used as a source port for this sender in this session. If the IP protocol in use, specified by intSrvResvFwdProtocol is 50 (ESP) or 51 (AH), this represents a generalized port identifier (GPI). A value of zero indicates that the IP protocol in use does not have ports. This ob- ject may not be changed when the value of the RowStatus object is 'active'.
PRO intSrvFlowProtocol	1.3.6.1.2.1.52.1.2.1.8	Protocol	read-create	The IP Protocol used by a session. This ob- ject may not be changed when the value of the RowStatus object is 'active'.
I32 intSrvFlowQueue	1.3.6.1.2.1.52.1.2.1.17	Integer32	read-create	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.
BIT intSrvFlowRate	1.3.6.1.2.1.52.1.2.1.14	BitRate	read-create	The Reserved Rate of the sender's data stream. If this is a Controlled Load service flow, this rate is derived from the Tspec rate parameter (r). If this is a Guaranteed service flow, this rate is derived from the Rspec clearing rate parameter (R).
OCT intSrvFlowSenderAddr	1.3.6.1.2.1.52.1.2.1.5	OCTET STRING	read-create	The source address of the sender selected by this reservation. The value of all zeroes in- dicates 'all senders'. This object may not be changed when the value of the RowStatus object is 'active'.
INT intSrvFlowSenderAddrLength	1.3.6.1.2.1.52.1.2.1.7	INTEGER	read-create	The length of the sender's address in bits. This is the CIDR Prefix Length, which for IP4 hosts and multicast addresses is 32 bits. This object may not be changed when the value of the RowStatus object is 'active'.
QOS intSrvFlowService	1.3.6.1.2.1.52.1.2.1.23	QosService	read-only	The QoS service being applied to this flow.
intSrvFlowsGroup	1.3.6.1.2.1.52.4.1.2			These objects are required for Systems sup- porting the Integrated Services Architecture.
ROW intSrvFlowStatus	1.3.6.1.2.1.52.1.2.1.25	RowStatus	read-create	'active' for all active flows. This object may be used to install static classifier infor- mation, delete classifier information, or au- thorize such.
intSrvFlowTable	1.3.6.1.2.1.52.1.2		not-accessible	Information describing the reserved flows us- ing the system's interfaces.
SES intSrvFlowType	1.3.6.1.2.1.52.1.2.1.2	SessionType	read-create	The type of session (IP4, IP6, IP6 with flow information, etc).
I32 intSrvFlowWeight	1.3.6.1.2.1.52.1.2.1.16	Integer32	read-create	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.
