Description: IETF Integrated Services MIB (RFC 2213) defining objects for RSVP-based per-flow quality of service management on network interfaces.

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 INT-SERV-MIB?

INT-SERV-MIB is the IETF Integrated Services MIB defined in RFC 2213, providing management objects for RSVP-based per-flow Quality of Service reservations on router interfaces, covering flow specifications, reserved bandwidth, and delay characteristics for real-time traffic. As a vendor-neutral standards MIB, it exposes general integrated-services objects alongside notification and conformance definitions for implementations claiming RFC 2213 compliance. Its monitoring value is in software/protocol status — the state and count of active per-flow reservations and how much bandwidth is committed on an interface — which helps operators see whether a link is approaching its integrated-services capacity or whether reservations are failing. It is closely tied to and dependent on RSVP as the signaling protocol that establishes the flows this MIB reports on, and reviewing the INT-SERV-MIB OID list shows the top-level branches are limited to general objects, notifications, and conformance groups rather than deep per-flow leaf tables. It is deployed on routers supporting RSVP/IntServ QoS, typically in networks carrying real-time voice/video traffic requiring per-flow bandwidth guarantees.

IPNetwork Monitor allows you to monitor SNMP objects defined in 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

  • vendor-neutral, standards-based MIB, not tied to a specific manufacturer; applies to routers supporting RSVP/Integrated Services QoS

Monitoring Examples

An admin would poll objects under the general objects branch (intSrvGenObjects) on a per-interface basis to see how many active RSVP flow reservations exist and how much bandwidth is committed, which would reveal whether a link is nearing its integrated-services capacity. The extracted sample only shows top-level object groups (intSrvObjects, intSrvGenObjects) and conformance groups (intSrvGroups, intSrvCompliances) rather than individual leaf counters, so specific reservation object names cannot be confirmed beyond this general per-flow QoS pattern.

What Can Be Monitored

  • active RSVP flow reservations
  • per-interface reserved bandwidth
  • integrated services QoS configuration
  • IntServ implementation conformance status
