Description: Hirschmann MMP4 QoS MIB for quality of service configuration on Hirschmann MMP4 industrial Ethernet switches.

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 HIRSCHMANN-MMP4-QOS-MIB?

HIRSCHMANN-MMP4-QOS-MIB is a Hirschmann enterprise MIB defining Quality of Service configuration for the MMP4 (Multi-Media Platform 4) family of Hirschmann industrial Ethernet switches. It centers on a class-of-service queue configuration group governing how traffic priorities are mapped to hardware egress queues on the switch. This MIB is primarily configuration-oriented, letting an administrator confirm the software-configured QoS priority-to-queue mapping matches intended industrial-network traffic engineering (e.g. prioritizing time-sensitive automation/control traffic), rather than reporting hardware faults directly. It is a platform-specific extension likely used alongside Hirschmann's broader HM2/MMP4 device MIBs for interface and system status. Typical deployment is on Hirschmann industrial Ethernet switches used in factory automation, process control, or ruggedized network environments requiring deterministic QoS, where HIRSCHMANN-MMP4-QOS-MIB SNMP monitoring confirms priority-to-queue mappings remain correctly applied.

IPNetwork Monitor allows you to monitor SNMP objects defined in HIRSCHMANN-MMP4-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.

Monitoring Examples

An administrator would poll the CoS queue configuration group (hmAgentCosQueueCfgGroup) to confirm per-priority traffic is mapped to the correct hardware queue on an MMP4 switch, verifying that industrial control-protocol traffic is assigned to a high-priority queue. An unexpected queue mapping here would explain why time-critical automation traffic is experiencing latency or jitter on the plant floor network. Since only the CoS queue config group name was available, exact per-port or per-priority object names should be confirmed against the MIB source.

I32 aclIfAclId	1.3.6.1.4.1.248.15.3.2.8.1.5	Integer32	not-accessible	The ACL identifier value, which is interpreted based on the aclIfType object. For the IP ACLs, the actual ACL number is its identifier as follows: IP standard ranges from 1-99, while IP extended ranges from 100-199. Here, aclIfAclId represents aclIndex. The MAC ACLs use an internally-generated index value that is assigned when the ACL is created.Here, aclIfAclId represents aclMacIndex. The aclIfType object must be specified along with this object.
INT aclIfAclType	1.3.6.1.4.1.248.15.3.2.8.1.4	INTEGER	not-accessible	The type of this ACL, which is used to interpret the aclIfId object value. Each type of ACL uses its own numbering scheme for identification (see aclIfId object for details). The aclIfId object must be specified along with this object.
INT aclIfDirection	1.3.6.1.4.1.248.15.3.2.8.1.2	INTEGER	not-accessible	The interface direction to which this ACL instance applies.

The value is specified in terms of percentage of overall link speed for the port in 1% increments. A value of 0 means there is no maximum bandwidth limit in effect and that the interface is allowed to transmit up to its maximum line rate (i.e., work conserving method). The default value is 0. When set to a non-zero value, the interface is restricted to using at most the bandwidth specified in this object for the outbound transmission rate (i.e., non-work-conserving method). This bandwidth value is independent of any per-queue maximum bandwidth value(s) in effect for the interface, as specified in the hmAgentCosQueueMaxBandwidth ohject, and should be considered as a second-level transmission rate control mechanism that regulates the output of the entire interface regardless of which queues originate the outbound traffic.
U32 hmAgentCosQueueMaxBandwidth	1.3.6.1.4.1.248.15.3.3.2.4.1.4	Unsigned32	read-write	Maximum bandwidth allowed for this queue, typically used to shape the outbound transmission rate. The value is specified in terms of percentage of overall link speed for the port in 1% increments. A value of 0 means there is no maximum bandwidth limit in effect and that the queue is allowed to use any available excess bandwidth (i.e., work conserving method). The default value is 0. When set to a non-zero value, the queue is restricted to using at most the bandwidth specified in this object for the outbound transmission rate (i.e., non-work-conserving method). Any non-zero value set for this object must be equal to or greater than the value of hmAgentCosQueueMinBandwidth for the same hmAgentCosQueueIndex on this interface.
INT hmAgentCosQueueMgmtType	1.3.6.1.4.1.248.15.3.3.2.4.1.5	INTEGER	read-write	The queue depth management technique used when per-queue specification is supported. If taildrop(1), then all new packets presented to the queue are dropped based on some maximum threshold value(s). If wred(2), then an active queue management scheme is employed whereby packet drop precedence is considered during times of queue congestion using WRED parameters. The necessary queue management parameters are specified in the hmAgentCosQueueMgmtEntry for the corresponding hmAgentCosQueueIntfIndex and hmAgentCosQueueIndex values. The default for this object is taildrop(1). Implementations that do not support weighted RED must return taildrop(1) for this value and must not allow a value of wred(2) to be set.
INT hmAgentCosQueueMgmtTypeIntf	1.3.6.1.4.1.248.15.3.3.2.3.1.3	INTEGER	read-write	The management technique used for all queues on this interface. If taildrop(1), then all new packets presented to the queues are dropped based on some maximum threshold value(s). If wred(2), then an active queue management scheme is employed whereby packet drop precedence is considered during times of queue congestion using WRED parameters. The necessary queue management parameters are specified in the hmAgentCosQueueMgmtTable for the corresponding hmAgentCosQueueIntfIndex value. The default for this object is taildrop(1). Implementations that support this object but do not support weighted RED must return taildrop(1) for this value and must not allow a value of wred(2) to be set.
U32 hmAgentCosQueueMinBandwidth	1.3.6.1.4.1.248.15.3.3.2.4.1.3	Unsigned32	read-write	Minimum guaranteed bandwidth allotted to this queue. The value is specified in terms of percentage of overall link speed for the port in 1% increments. A value of 0 means there is no guaranteed minimum bandwidth in effect (best-effort service). The default value is 0. The sum of all hmAgentCosQueueMinBandwidth object values for the queues on the same interface must not exceed 100%. If the hmAgentCosQueueMaxBandwidth corresponding to the same hmAgentCosQueueIndex on this interface is currently set to a non-zero value, then setting this object to a value greater than hmAgentCosQueueMaxBandwidth automatically updates hmAgentCosQueueMaxBandwidth to the same value to maintain a proper relationship between the minimum and maximum queue bandwidth specification. The value of this object is ignored when hmAgentCosQueueSchedulerType is set to strict(1).
U32 hmAgentCosQueueNumDropPrecedenceLevels	1.3.6.1.4.1.248.15.3.3.2.2	Unsigned32	read-only	The number of distinct drop precedence levels per queue supported by the hardware device. These levels are typically used when configuring the queue management tail drop and WRED parameters.
U32 hmAgentCosQueueNumQueuesPerPort	1.3.6.1.4.1.248.15.3.3.2.1	Unsigned32	read-only	The number of configurable COS queues per port supported by the hardware device.
INT hmAgentCosQueueSchedulerType	1.3.6.1.4.1.248.15.3.3.2.4.1.2	INTEGER	read-write	The type of scheduling used for this queue. If strict(1), then all traffic placed on this queue is transmitted before any queue with a lower precedence (lower hmAgentCosQueueIndex). A weighted(2) scheme gives this queue service relative to other weighted queues based on their relative hmAgentCosQueueMinBandwidth object values. The default is weighted(2).
hmAgentCosQueueTable	1.3.6.1.4.1.248.15.3.3.2.4		not-accessible	Table of class-of-service queue configuration parameters for the specified interface.
U32 hmAgentCosQueueWredDecayExponent	1.3.6.1.4.1.248.15.3.3.2.3.1.4	Unsigned32	read-write	The decay exponent value used with the weighted random early discard (WRED) algorithm to determine how quickly the average queue length calculation reacts to the current length of the queue. A higher value produces a slower response, meaning previously sampled queue length values are factored into the calculation for a longer period of time. The default value is 9. Use caution when changing this value from its default. If set too low, short traffic bursts can cause WRED to drop too many packets. If set too high, WRED might not detect queue congestion in a timely manner and becomes ineffective. The default value should be sufficient for most users. This object value is only used when the hmAgentCosQueueMgmtType is set to wred(2) and is otherwise ignored.
hmAgentQOSACL	1.3.6.1.4.1.248.15.3.2
hmAgentQOSCOS	1.3.6.1.4.1.248.15.3.3
hmPlatform4QOS	1.3.6.1.4.1.248.15.3			The Hirschmann Private Platform4 QoS MIB definitions for Platform devices.
