What Is EXTREME-QOS-MIB?
EXTREME-QOS-MIB is an Extreme Networks enterprise MIB defining objects for configuring and monitoring Quality of Service (QoS) on Extreme switches, covering traffic classification, scheduling policies, and queue/class-of-service assignment. It primarily exposes configuration data -- how traffic classes and scheduling policies are defined and applied -- though such tables typically also carry counters useful for monitoring queue behavior and policy enforcement. Its role in device monitoring is to confirm QoS software configuration is correctly applied and, where counters exist, to reveal traffic-class drop or queuing behavior that could indicate congestion. It is a self-contained vendor MIB, generally used alongside standard interface and traffic MIBs for a complete picture of switch performance. It is deployed on Extreme Networks switches in environments (campus, data center) that need prioritized handling of latency-sensitive traffic like voice or video. Network engineers evaluating or troubleshooting this functionality can download the EXTREME-QOS-MIB file directly to load it into their MIB browser.
IPNetwork Monitor allows you to monitor SNMP objects defined in EXTREME-QOS-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
- QoS traffic class configuration
- scheduling policy assignment
- queue/class-of-service mapping
Supported Devices
- Extreme Networks switch
Monitoring Examples
No sample_objects are provided for this MIB, so specific table/object names cannot be cited; based on its short description one would expect tables for QoS traffic classes and per-port scheduling policy assignment. An admin would typically poll such tables to confirm a voice traffic class is mapped to a high-priority queue, and check any associated counters for unexpected packet drops indicating congestion. This characterization is inferred from the description rather than confirmed object names.
OIDs
| OID symbolic | OID numeric | Type | Access | Description |
|---|---|---|---|---|
| extremeQos | 1.3.6.1.4.1.1916.1.3 | Extreme Quality-of-Service objects | ||
| extremeQosCommon | 1.3.6.1.4.1.1916.1.3.1 | |||
| INT extremeUnitPaceMode | 1.3.6.1.4.1.1916.1.3.1.1 | INTEGER | read-write | This object specifies whether the device currently recognises and gives priority treatment to the forwarding of packets with the PACE(tm) bit set in their MAC Source Address fields. PACE(tm) mode applies to the whole unit only and is only valid when device is in Ingress QoS mode as specified by extremeQosMode ingress(1). This object will report notApplicable(1) when in egress(2) mode. Set operations with value notApplicable(1) will be rejected. |
| INT extremeQosMode | 1.3.6.1.4.1.1916.1.3.1.4 | INTEGER | read-write | Indicates which QoS mode the device should use. ingress(1) applies priority-based QoS based on the incoming packet's destination IP or MAC address, 802.1p priority, PACE(tm), Source Port or VLAN. egress(2) applies priority- and bandwidth-based QoS based on destination IP or MAC address or VLAN. See ExtremeWare documentation for further information. |
| T/F extremeQosUnconfigure | 1.3.6.1.4.1.1916.1.3.1.5 | TruthValue | read-write | Setting this to true will reset all QoS settings in the device to factory defaults. Reads from this value return an undefined value. |
| extremeQosProfileTable | 1.3.6.1.4.1.1916.1.3.1.6 | not-accessible | This table lists QoS profiles. | |
| extremeQosProfileEntry | 1.3.6.1.4.1.1916.1.3.1.6.1 | not-accessible | An individual QoS profile Entry. | |
| INT extremeQosProfileIndex | 1.3.6.1.4.1.1916.1.3.1.6.1.1 | INTEGER | read-create | An index that uniquely identifies an entry in the qos table. |
| STR extremeQosProfileName | 1.3.6.1.4.1.1916.1.3.1.6.1.2 | DisplayString | read-create | A unique qos profile name. |
| INT extremeQosProfileMinBw | 1.3.6.1.4.1.1916.1.3.1.6.1.3 | INTEGER | read-create | The minumum percentage of bandwidth that this queue requires. The Switch is required to provide the minumum amount of bandwidth to the queue. The lowest possible value is 0%. |
| INT extremeQosProfileMaxBw | 1.3.6.1.4.1.1916.1.3.1.6.1.4 | INTEGER | read-create | The maximum percentage of bandwidth that this queue is permitted to use. If a non-default value is set for this object then it negates any previously set value of extremeQosProfileMaxSustBwBps. In In addition, a set operation that supplies non-default values for both this object and for extremeQosProfileMaxSustBwBps will be rejected by the agent. In other words, you may supply either an absolute or a percent limit, not both. |
| INT extremeQosProfilePriority | 1.3.6.1.4.1.1916.1.3.1.6.1.5 | INTEGER | read-create | The level of priority in which this queue will be serviced by the Switch. |
| ROW extremeQosProfileRowStatus | 1.3.6.1.4.1.1916.1.3.1.6.1.6 | RowStatus | read-create | The status of the extremeQosProfile entry. This object can be set to: active(1) createAndGo(4) createAndWait(5) destroy(6) The following values may be read: active(1) notInService(2) notReady(3). Setting this object to createAndGo(4) causes the agent to attempt to create and commit the row based on the contents of the objects in the row. If all necessary information is present in the row and the values are acceptible to the agent, the agent will change the status to active(1). If any of the necessary objects are not available, the agent will reject the creation request. Setting this object to createAndWait(5) causes a row in this table to be created. The agent sets the status to notInService(2) if all of the information is present in the row and the values are acceptable to the agent; otherwise, the agent sets the status to notReady(3). Setting this object to active(1) is only valid when the current status is active(1) or notInService(2). When the state of the row transitions is set to active(1), the agent creates the corresponding row in the ifTable.. Setting this object to destroy(6) will remove the corresponding QoS Profile Entry. In order for a set of this object to destroy(6) to succeed, all dependencies on this row must have been removed. These will include any stacking dependencies in the ifStackTable and any protocol specific tables dependencies. |

| INT extremePerPortQosMinBw | 1.3.6.1.4.1.1916.1.3.1.8.1.2 | INTEGER | read-create | The minumum percentage of bandwidth that this queue on the specified port requires. The Switch is required to provide the minumum amount of bandwidth to the queue. The lowest possible value is 0%. |
