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.
What Can Be Monitored
- per-interface IntServ enablement
- RSVP reservation state
- general resource allocation parameters
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.

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). |
| 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. |
| 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. |

| 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. |
| QOS intSrvFlowService | 1.3.6.1.2.1.52.1.2.1.23 | QosService | read-only | The QoS service being applied to this flow. |
| 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. |
| 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. |
| intSrvGenObjects | 1.3.6.1.2.1.52.2 | |||
| 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. |
