An Avaya Network's management module containing data definitions related to QoS components and services supported by network devices.

Interface type definitions. This class describes the types of interfaces that exist on the device. An interface type is denoted by its designated role identifier.

An instance of this class describes the characteristics of a type of an interface. Interface type characteristics include a role combination identifier, an interface class designation and a filter capabilities attribute. An instance is required for each different unique role combination identifier which represents the different interface types that are operational in the device at any given time. The PEP does not report which specific interfaces have which characteristics.

An arbitrary integer index that uniquely identifies a instance of the ntnQosInterfaceType class. Class instances may not be contiguous.

The role combination that is used to identify interfaces with the characteristics specified by the attributes of this class instance. Interface role combination identifiers are used within a number of classes to logically identify a physical set of interfaces to which policy rules and actions are applied. Role combination identifiers must exist in this table prior to being referenced in other class instances.

A value describing the overall classification of traffic received on interfaces with the given role combination. Traffic received on trusted interfaces may be processed differently and be subject to different restrictions that traffic received on non-trusted interfaces. The treatment of traffic based on interface class is implementation dependent. Enumeration: 'nonTrusted': 2, 'unrestricted': 3, 'trusted': 1.

An enumeration of interface capabilities. Used by the PDP or network manager to select which policies and configuration it should push to the PEP. Bits: 'output802Classification': 4, 'outputIpClassification': 2, 'other': 0, 'input802Classification': 3, 'inputIpClassification': 1.

An instance of the ntnQosShapingParams class.

An index that is used to uniquely identify the instance of the ntnQosShapingParams class.

The maximum rate, in kilobits per second, at which traffic shaped using this rate criteria will be transmitted over a given period of time. Transmitted traffic may exceed this rate for short periods in accordance with the associated burst size. Typically, this value specifies the rate at which tokens are added to a token bucket used to shape flows. This object specifies a rate in kilobits per second units such that, for example, a value of 100 equates to a shaped flow being transmitted at a maximum rate of 100,000 bits per second.

The maximum traffic burst size, in bytes, that can be transmitted without experiencing a shaping delay. Typically, this value represents the maximum number of tokens in a token bucket. Note that the value of this attribute may modified in an implementation dependent, such as being rounded down to an acceptable value, to account for system limitations.

The amount of traffic, in packets, that may exceed the maximum burst size and still be queued for transmission. This value specifies the size of a shaping queue that holds a flow's traffic that is being delayed for shaping purposes. The specified enumeration dictates whether one ('onePkt'), two ('twoPkts'), four ('fourPkts'), eight, ('eightPkts') or sixteen ('sixteenPkts') packets can be held in the shaping queue prior to transmission. Enumeration: 'fourPkts': 3, 'sixteenPkts': 5, 'eightPkts': 4, 'twoPkts': 2, 'onePkt': 1.

IEEE 802-based classifier definitions. A class that contains attributes of IEEE 802 (e.g., 802.3) traffic that form an association that is used to perform traffic classification.

IEEE 802-based classifier definitions. An entry specifies (potentially) several distinct matching components. Each component is tested against the data in a frame individually. An overall match occurs when all of the individual components match the data they are compared against in the frame being processed. A failure of any one test causes the overall match to fail. Wildcards may be specified for those fields that are not relevant.

An arbitrary integer index that uniquely identifies this 802 classifier among all of the 802 classifiers. Version 1/2 attribute.

The 802 address against which the 802 DA of incoming traffic streams will be compared. Frames whose 802 DA matches the physical address specified by this object, taking into account address wildcarding as specified by the ntnL2MultiFieldClfrDstAddrMask object, are potentially subject to the processing guidelines that are associated with this entry through the related action class. Version 1/2 attribute.

This object specifies the bits in a 802 destination address that should be considered when performing a 802 DA comparison against the address specified in the ntnL2MultiFieldClfrDstAddr object. The value of this object represents a mask that is logically and'ed with the 802 DA in received frames to derive the value to be compared against the ntnL2MultiFieldClfrDstAddr address. A zero bit in the mask thus means that the corresponding bit in the address always matches. The ntnL2MultiFieldClfrDstAddr value must also be masked using this value prior to any comparisons. The length of this object in octets must equal the length in octets of the ntnL2MultiFieldClfrDstAddr. Note that a mask with no bits set (i.e., all zeroes) effectively wildcards the ntnL2MultiFieldClfrDstAddr object. Version 1/2 attribute.

Frames whose 802 MAC SA matches the physical address specified by this object, taking into account address wildcarding as specified by the ntnL2MultiFieldClfrSrcAddrMask object, are potentially subject to the processing guidelines that are associated with this entry through the related action class. Version 1/2 attribute.

This object specifies the bits in a 802 MAC source address that should be considered when performing a 802 MAC SA comparison against the address specified in the ntnL2MultiFieldClfrSrcAddr object.

A zero bit in the mask thus means that the corresponding bit in the address always matches. The ntnL2MultiFieldClfrSrcAddr value must also be masked using this value prior to any comparisons. The length of this object in octets must equal the length in octets of the ntnL2MultiFieldClfrSrcAddr. Note that a mask with no bits set (i.e., all zeroes) effectively wildcards the ntnL2MultiFieldClfrSrcAddr object. Version 1/2 attribute.

The minimum value that the VLAN ID (VID) in a tagged packet must have in order to match this classifier entry. The ntnL2MultiFieldClfrVlanIdMin value must be less than or equal to the ntnL2MultiFieldClfrVlanIdMax value. Setting the ntnL2MultiFieldClfrVlanIdMin object to 1 and the ntnL2MultiFieldClfrVlanIdMax to 4094 indicates that VLAN data should not be considered during traffic classification. If a frame is double tagged, this value represents the outer VLAN ID (Ovid). Version 1/2 attribute.

The maximum value that the VLAN ID (VID) in a tagged packet must have in order to match this classifier entry. The ntnL2MultiFieldClfrVlanIdMax value must be greater than or equal to the ntnL2MultiFieldClfrVlanIdMin value.

A value of 'doubleTagged(4)' means that only frames received with an inner and outer tag (i.e., a double tagged frame) will be considered a match. Version 1/2 attribute. Enumeration: 'ignore': 3, 'untagged': 1, 'tagged': 2, 'doubleTagged': 4.

This object specifies the value that will be compared against the value contained in the EtherType field of an IEEE 802 frame. Example settings would include 'IP' (0x0800), 'ARP' (0x0806) and 'IPX' (0x8137). Setting the ntnL2MultiFieldClfrEtherType object to 0xFFFF indicates that EtherType data should not be considered during traffic classification. Note the EtherType value of 0xFFFF is reserved by IANA. Version 1/2 attribute.

The 802.1p user priority value against which the value contained in the user priority field of a tagged 802.1 frame is compared. A test for equality is performed when determining if a match exists between the data in a data link layer frame and the value of this classifier. Setting the value of this object to 'matchAllPriorities(9)' causes all user priority values to match this attribute. This essentially makes any comparisons with regard to user priority values unnecessary. Version 1/2 attribute.

The maximum value that the Inner VLAN ID (Ivid) in a double tagged packet must have in order to match this classifier entry. The ntnL2MultiFieldClfrIvidMax value must be greater than or equal to the ntnL2MultiFieldClfrIvidMin value. Setting the ntnL2MultiFieldClfrIvidMin object to 1 and the ntnL2MultiFieldClfrIvidMax to 4094 indicates that VLAN data should not be considered during traffic classification.

Supports arbitrary pattern match classification. Up to 128 bytes of data within the first 128 bytes of a packet can be identified for pattern matching purposes. This object and the ntnSystemClfrPatternData object specify byte patterns and their position in a packet. When a packet is classified using this data, the appropriate bytes, or portions thereof, in the packet are compared against the byte patterns defined by the ntnSystemClfrPatternData attribute. If the data at the specified packet offset is the same, the packet is considered a match. The byte positions, and the pertinent bits within each identified byte, used for comparison purposes are specified using this attribute. The positions to be matched are identified by setting the appropriate bits to one. All other bits must be set to zero. For example, to specify that byte positions 5-8 and the high-order nibble (4 bits) of bytes 13-16 should be examined, this attribute would be set as follows: ntnSystemClfrPatternPosition (size 16): 00:00:00:00:FF:FF:FF:FF:00:00:00:00:0F:0F:0F:0F The target byte patterns would then be placed in bytes 5-8 and in portions of bytes 13-16 of the ntnSystemClfrPatternData attribute: ntnSystemClfrPatternData (size 16): 00:00:00:00:XX:XX:XX:XX:00:00:00:00:0Y:0Y:0Y:0Y Note that an implementation may not support pattern matching, also know as offset filtering, for the maximum number of bytes supported by the pattern match attributes. The number of bytes that can contain data for comparison purposes and the position of those bytes in relation to the start of a packet are thus implementation dependent. Use of this object and the associated ntnSystemClfrPatternData object invalidates the use of any other classification data in this and related (through the ntnClfrComponentTable) classifier entries. In other words, providing an explicit pattern overrides the implicit patterns defined when classification data is specified for other fields, such as the IP source address or EtherType classification attributes. A zero length string is used to indicate that explicit pattern matching is not requested. Version 1/2 attribute.

Supports arbitrary pattern match classification. Up to 128 bytes of data within the first 128 bytes of a packet can be identified for pattern matching purposes. This object and the ntnSystemClfrPatternPosition object specify byte patterns and their position in a packet. When a packet is classified using this data, the appropriate bytes, or portions thereof, in the packet are compared against the byte patterns defined by the this attribute. If the data at the specified packet offset is the same, the packet is considered a match. The byte patterns used for comparison purposes are specified using this attribute. The target data is placed in the octet string at the positions specified through the ntnSystemClfrPatternPosition attribute. All other bytes should be set to zero For example, to specify that byte positions 5-8 and the high-order nibble (4 bits) of bytes 13-16 should be examined, the associated ntnSystemClfrPatternPosition value would be set as follows: ntnSystemClfrPatternPosition (size 16): 00:00:00:00:FF:FF:FF:FF:00:00:00:00:0F:0F:0F:0F The target byte patterns would then be placed in bytes 5-8 and in portions of bytes 13-16 of this attribute: ntnSystemClfrPatternData (size 16): 00:00:00:00:XX:XX:XX:XX:00:00:00:00:0Y:0Y:0Y:0Y Note that an implementation may not support pattern matching, also know as offset filtering, for the maximum number of bytes supported by the pattern match attributes. The number of bytes that can contain data for comparison purposes and the position of those bytes in relation to the start of a packet are thus implementation dependent. Use of this object and the associated ntnSystemClfrPatternPosition object invalidates the use of any other classification data in this and related (through the ntnClfrComponentTable) classifier entries. In other words, providing an explicit pattern overrides the implicit patterns defined when classification data is specified for other fields, such as the IP source address or EtherType classification attributes. A zero length string is used to indicate that explicit pattern matching is not requested. Version 1/2 attribute.

This object contains an unused value for ntnQosBaseActionId, or a zero to indicate that none exist.

Contains the current set of configured base actions. The actions are associated with classifiers, meters and interfaces through policies during operation.

General action definitions. Each entry specifies an instance of the ntnQosBaseAction class which describes (potentially) several distinct action attributes. Each action is taken individually regarding the data in question. Several actions can be taken for a single frame. An instance of this class cannot be deleted while it is being referenced by an entry in another class.

An index that enumerates the QoS Base Action entries. Managers can obtain new index values for row creation in this table by reading ntnQosBaseActionNextFree. Actions are associated with instances in other classes (e.g., the QoS Policy class) using this attribute.

This action attribute is used to specify whether a packet should dropped, switched (i.e., not dropped) or whether the decision to drop the packet should be deferred. The value 'drop(1)', when specified, will cause the packet being evaluated to be dropped. A value of 'dontDrop(2)' indicates that this packet should not be dropped. A value of 'deferredPass(3)' indicates that no explicit assertion, related to whether or not the packet should be discarded, is being made. This option, when available, can be used to allow actions associated with lower precedence policies to determine whether a packet should be dropped or not. A 'drop(1)' or 'dontDrop(2)' in a lower precedence action is given precedence over a higher precedence 'deferredPass(3)'. Support for this enumeration is implementation dependent. Prior to discarding a packet, other actions that have been specified should be performed if they make protocol sense. For example, requests for traffic mirroring (if such an action is supported by a device) should be honored. However, updating protocol header values will typically not be necessary. Enumeration: 'drop': 1, 'deferredPass': 3, 'dontDrop': 2.

This action component, when specified, will cause the value contained in the Differentiated Services (DS) field of an associated IP datagram to be updated with the value of this object.

This action attribute, when specified, will cause the value contained in the user priority field of the 802.1Q frame to be updated based on the value of this object. Specifying a value equal to 'deriveFromIngressTosPrec(9)' means that the value for this attribute will be assigned based on the value of the precedence bits in the IP Type-Of-Service (TOS) field, as defined in RFC 791. The eight precedence values, also referred to as Class Selector (CS) values, have a one-to-one correspondence with the eight 802.1p user priority values. Specifying a value equal to 'deriveFromIngressDscp(10)' means that the value for this attribute will be assigned based on DSCP-to-user priority map information maintained in the system. The DSCP value in received traffic will be used to determine the user priority. Specifying a value equal to 'deriveFromEgressDscp(11)' means that the value for this attribute will be assigned based on DSCP-to-user priority map information maintained in the system. The DSCP value specified for remarking in the ntnQosBaseActionUpdateDscp attribute will be used to determine the user priority. Specifying a value equal to 'ignore(12)' means that no action will be taken related to this attribute. Specifying a value equal to 'markAsPriorityCopy(13)' means that the priority is updated based on the user priority field in the outer vlan tag. The priority copy functionality can be used for 802.1ad double tagged traffic where the priority field in the service provider vlan tag can be copied from the user priority in the customer vlan tag. Enumeration: 'ignore': 12, 'deriveFromIngressTosPrec': 9, 'markAsPriorityCopy': 13, 'deriveFromIngressDscp': 10, 'markAsPriority2': 3, 'markAsPriority3': 4, 'markAsPriority0': 1, 'markAsPriority1': 2, 'markAsPriority6': 7, 'markAsPriority7': 8, 'markAsPriority4': 5, 'markAsPriority5': 6, 'deriveFromEgressDscp': 11.

This action attribute, when specified, will cause the packet being evaluated to be associated with the specified relative drop precedence. The relative drop precedence may be used to determine traffic precedence relative to other traffic being processed by the device and other implementation specific operations at the egress interface. A low value for the drop precedence equates to the traffic receiving a higher priority in terms of processing. In other words, when congestion is encountered, packets with a 'highDropPrec(2)' will be dropped before packets with a 'lowDropPrec(1)'. Enumeration: 'lowDropPrec': 1, 'highDropPrec': 2.

This action attribute, when specified, has the ability to cause the packet being evaluated to be sent to the CPU for further processing. Extreme care should be taken when setting this object to 'true(1)' since this action may adversely affect resource availability in the system impacting overall system operation. A value of 'false(2)' indicates that this action will not be initiated. If this operation is requested and 'drop' has been specified, the packet will be sent to the CPU and not forwarded by the system. Specifying 'true(1)' when 'drop' has not been specified will cause a copy of the packet to be sent to the CPU and the packet itself will receive normal forwarding treatment.

This action attribute, when specified, will cause the packet being evaluated to be sent to a predefined egress port for transmission in addition to the normal processing associated with the packet. Specification of the egress port or ports that will serve as the destination for mirrored data is beyond the scope of this document. Furthermore, note that data mirroring can potentially consume substantial resources at the egress. Over-subscription issues should be considered prior to specifying this action. A value of 'false(2)' indicates that this action will not be initiated. If this operation is requested and 'drop' has been specified, the packet will be mirrored to the specified port and not forwarded by the system. Specifying 'true(1)' when 'drop' has not been specified will cause a copy of the packet to be mirrored and the packet itself will receive normal forwarding treatment.

Identifies an entry in an auxiliary action table containing additional actions to be performed on/applied to identified traffic. Entries are referenced using a RowPointer value specifying the RowStatus attribute of the entry being identified. Entries in other tables must exist prior to being referenced. It may be permissible to create base table entries and the entries being referenced in the same request. Referenced entries may not be deleted while still referenced by an active entry in this table. A null value for this attribute (0.0) indicates that no action extensions have been specified.

A label used to reference the action entry in a textual manner.

The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. This object may not be modified if the associated status object is equal to 'active'.

This object contains an unused value for ntnQosIfcActionId, or a zero to indicate that none exist.

Contains the current set of configured interface actions. The actions are associated with classifiers, meters and interfaces through policies during operation indirectly through extensions of other action entries.

Interface action definitions. Each entry specifies an instance of the ntnQosIfcAction class which describes (potentially) several distinct action attributes. Each action is taken individually regarding the data in question. Several actions can be taken for a single frame. An instance of this class cannot be deleted while it is being referenced by an entry in another class.

An index that enumerates the QoS Interface Action entries. Managers can obtain new index values for row creation in this table by reading ntnQosIfcActionNextFree. Actions are associated with instances in other classes (e.g., the QoS Base Action class) using this attribute as a component in the identifying RowPointer.

This action attribute, when specified, will cause the Vlan Id in the frame being processed to be updated using the specified value. The Vlan Id value will not be updated based on QoS classification if the value of this attribute equals -1.

This action component, when specified, will cause the potential list of egress interfaces for a given packet to be limited to those interfaces that are included in the egress interface mask specified by this attribute. A packet will only be transmitted out interfaces that are both identified through this attribute AND through the normal forwarding logic. Potential egress interfaces are identified by setting the bit in the egress mask that corresponds to the ifIndex value associated with the interface. Each bit of this bit mask corresponds to an ifIndex value, with the most significant bit of the i-th octet of this octet string corresponding to the ((8*i) - 7)-th ifIndex, and the least significant bit of the i-th octet corresponding to the (8*i)-th ifIndex. A zero length octet string indicates that this action component has not been set to an appropriate value and should not be used for action initiation. Egress interface restrictions will not be updated based on QoS classification in this case.

This action attribute supports redirection of normally-switched, known unicast packets to a specific interface. An egress interface is identified for redirection by setting this attribute to the logical ifIndex value associated with the interface. Setting this attribute to 0 indicates that redirection of unicast traffic based on QoS classification is not requested. Specifying the same ifIndex value for this object and the ntnQosIfcActionSetEgressNUcastIfc attribute causes all traffic to be redirected if it matches specified QoS classification criteria.

This action attribute supports redirection of normally-switched non-unicast (includes broadcast, multicast and flooded/unknown unicast) packets to a specific interface. An egress interface is identified for redirection by setting this attribute to the logical ifIndex value associated with the interface. Setting this attribute to 0 indicates that redirection of non-unicast traffic based on QoS classification is not requested. Specifying the same ifIndex value for this object and the ntnQosIfcActionSetEgressUcastIfc attribute causes all traffic to be redirected if it matches specified QoS classification criteria.

Identifies an entry in an auxiliary action table containing additional actions to be performed on/applied to identified traffic. Entries are referenced using a RowPointer value specifying the RowStatus attribute of the entry being identified. Entries in other tables must exist prior to being referenced. It may be permissible to create referencing table entries and the entries being referenced in the same request. Referenced entries may not be deleted while still referenced by an active entry in this table. A null value for this attribute (0.0) indicates that no action extensions have been specified.

A value of 'blockOfClfrs(2)' means the value reference entries in the Classifier Block Table (ntnClfrBlockTable) using the classification block number. The values 'filterSetIndividualClfr(3)' and 'filterSetBlockOfClfrs(4)' can only be retrieved. Version 1/2 attribute. Enumeration: 'blockOfClfrs': 2, 'filterSetIndividualClfr': 3, 'individualClfr': 1, 'filterSetBlockOfClfrs': 4.

This attribute identifies the classification data that is associated with this policy. It identifies either an individual classifier or a block of classifiers, based on the value of the ntnQosPolicyClassifierType attribute.

A value of 'blockOfClfrs(2)' means this value reference entries in the Classifier Block Table (ntnClfrBlockTable) using the classification block number Referenced classification data must be defined prior to being referenced. Version 1/2 attribute.

The interfaces to which this policy applies, specified in terms of a set of roles. The role combination specified by this attribute must exist in the ntnQosInterfaceTypeTable or the individual roles must exist in the ntnQosInterfaceRoleTable prior to being associated with an instance of this class. Version 1/2 attribute.

The corresponding instance in the ntnQosMeter class (i.e., the class instance where the ntnQosMeterId is equal to the value of this object) must exist prior to being associated with a policy entry. A value of 0 indicates that no metering is requested. Version 1/2 attribute.

This attribute identifies the action that is to be initiated for flows that are not being metered and that match the classification criteria specified via the classifier attributes. The value of this attribute will not be used (and should be set to 0) when metering is requested. Under this scenario, the in-profile and out-of-profile actions are specified through the appropriate ntnQosMeterEntry. Actions must be defined in the ntnQosBaseActionTable prior to being referenced by this attribute. A non-zero value for this attribute must be provided unless metering is requested.

The type of statistics tracking used by this QoS policy. The value of this attribute dictates the amount of statistics tracking resources (i.e., counters) consumed by this policy. A value of 'individualClfr(1)' means that separate counters will be allocated, space permitting, for each classifier referenced by the policy. A value of 'aggregateClfr(2)' means that a single counter will be used to accumulate the statistics data for all the classifiers referenced by the policy. The value of this attribute is only used when statistics tracking is enabled for the overall policy through the ntnQosPolicyStats attribute. Version 1/2 attribute. Enumeration: 'aggregateClfr': 2, 'individualClfr': 1.

An ifIndex value that is used to identify an interface to which the policy is to be applied. A policy is associated with an interface explicitly using this attribute or implicitly using a role combination through the ntnQosPolicyInterfaceRole attribute. An interface must be identified by one and only one of these attributes. This attribute may identify an interface that does not currently exist in the system as long as the specified interface index represents a potentially valid system interface. Version 1/2 attribute.

If the identified policy references an individual classifier (as specified by the QoS Policy Table ntnQosPolicyClassifierType attribute), the value of this attribute will be the referenced classifier component set ID. If a block of classifiers is specified, the value of this attribute will be the classifier component set identifier referenced by the block member. A special value (0) for this attribute indicates that aggregate, not individual, statistics are being maintained for the referenced policy. In this case, the filter ID of 0 should be thought of as a wildcard identifying all the classifiers associated with the policy.

Also used to derive the capabilities that are common across several interfaces. Bits: 'meteringBucket512K': 9, 'shapingTypeInterface': 23, 'outputSystemClassification': 6, 'meteringGranularity1000Kbps': 12, 'shapingGranularity64Kbps': 17, 'shapingGranularity1000Kbps': 18, 'version1Caps': 25, 'inputIpClassification': 1, 'output802Classification': 4, 'shapingTypeCos': 24, 'meteringBucket8192K': 10, 'meteringBucket16384K': 29, 'shapingRate32767': 28, 'meteringRate1023': 7, 'other': 0, 'input802Classification': 3, 'shapingRate16383': 14, 'meteringTypeSimpleTb': 20, 'meteringRate32767': 27, 'meteringGranularity64Kbps': 11, 'dappSupport': 31, 'shapingBucket512K': 15, 'actionIPv6Remarking': 19, 'shapingBucket16384K': 30, 'outputIpClassification': 2, 'version2Caps': 26, 'meteringTypeSrTcm': 21, 'shapingRate1023': 13, 'inputSystemClassification': 5, 'meteringRate16383': 8, 'meteringTypeTrTcm': 22, 'shapingBucket8192K': 16.

Contains information about the individual queues that comprise a queue set implemented on the device.

A conceptual row in the ntnQosIfQueueTable. Each row identifies a specific queue within a given queue set and contains detailed information about the queue. Queues are associated with a given set through this table and a queue set is associated with an interface through the ntnQosIfAssignmentTable.

An index that uniquely identifies an entry in the ntnQosIfQueueTable.

An index that uniquely identifies a specific queue set. The queue set that is identified with this value is associated with an interface through the ntnQosIfAssignmentQueueSet object in the ntnQosIfAssignmentTable. The individual queues that are members of this set all have the same value for this attribute (i.e., they have the same set ID).

An arbitrary index that uniquely identifies a specific queue within a set of queues that is identified by the ntnQosIfQueueSetId value.

This object identifies the queuing discipline that is associated with the specified queue. A value of fifo(1) indicates that the queue is serviced on a first-in-first-out (FIFO) basis. This discipline is generally employed when only a single queue is available for a given interface. A value of pq(2) indicates that the queue is serviced using a priority queuing discipline. This technique is used when several queues are available for a given interface. Each queue is assigned a priority and queues are serviced in order of priority. Higher priority queues are completely drained before lower priority queues are serviced. A value of fq(3) indicates that the queue is serviced using a fair queuing discipline. This technique is used when several queues are available for a given interface. Each queue is treated equally and is serviced in a round-robin fashion. A value of wfq(4) indicates that the queue is serviced using a weighted fair queuing discipline. This technique is used when several queues are available for a given interface. Each queue is serviced based on queue weights which determine the scheduling and frequency of queue servicing. Queues that are assigned a greater weight are implicitly provided with more bandwidth. A value of wrr(5) indicates that the queue is serviced using a weighted round robin discipline. This technique is used when several queues are available for a given interface. Each queue is serviced based on queue weights which determine the scheduling and frequency of queue servicing. Queues that are assigned a greater weight are implicitly provided with more bandwidth. Note that the processing disciplines for all of the queues in a given set must be considered when trying to establish a processing profile for a given interface. Enumeration: 'fq': 3, 'pq': 2, 'wrr': 5, 'wfq': 4, 'fifo': 1.

The maximum number of bytes that may be drained from the queue in one cycle. The percentage of the interface bandwidth allocated to this queue can be calculated from this attribute and the sum of the drain sizes of all the queues in a specific queue cluster in a queue set. This attribute represents the relative bandwidth that is available to a given queue with respect to other queues with which it is associated. The absolute bandwidth that is available to a given queue is specified by the attribute ntnQosIfQueueAbsBandwidth. Which of these two applies is specified by the attribute ntnQosIfQueueBandwidthAllocation.

The maximum interface bandwidth that is available for consumption when servicing this queue. This bandwidth is specified in terms of kilobits per second. This attribute represents the absolute bandwidth that is available to a given queue. The relative bandwidth that is available to a given queue, with respect to other queues with which it is associated, is specified by the attribute ntnQosIfQueueDrainSize. Which of these two applies is specified by the attribute ntnQosIfQueueBandwidthAllocation.

This attribute specifies whether to configure the queue for an absolute bandwidth limit or one that is relative to other queues of the interface. i.e., whether to configure the queue using ntnQosIfQueueAbsBandwidth or ntnQosIfQueueDrainSize. Enumeration: 'relative': 2, 'absolute': 1.

This object is used to provide an additional level of priority that is required for certain queuing disciplines and when the different queues that comprise a queue set are serviced using a mix of queuing disciplines. This object can be used to specify, for example, the order in which queues will be serviced when priority queuing is used. It also supports the ability to describe the servicing hierarchy when a hybrid queuing scheme, such as priority queuing coupled with weighted fair queuing, is used. Queue service priority is assigned such that a lower service order value indicates a higher priority. For example, a priority queue with a value of 1 will be serviced (i.e., drained) before another priority queue with a service order value of 2. Note that multiple queues that are logically associated, based on the queuing discipline that is being employed, will be assigned the same service order value. Under this scenario, other parameters that are related to the queuing discipline determine the order of queue servicing (e.g., queue drain size is used for 'wfq'). For example, an interface that is associated with a queue set supporting two priority queues and three queues that are serviced using WFQ would be modeled as follows: Q Index Q Discipline Q Drain Size Q Service Order 22 pq(1) - 1 23 pq(1) - 2 24 wfq(3) 500 3 25 wfq(3) 350 3 26 wfq(3) 150 3 The queue set presented in this example would service all queued traffic in queue 22 first, followed by all of the queued traffic in queue 23. Next the queued traffic in queues 24 through 26 would be serviced in a round robin fashion with queue 24 receiving 50% of the available bandwidth, queue 25 receiving 35% of the available bandwidth and queue 26 receiving 15% of the available bandwidth. This example is presented for expository purposes and has been simplified accordingly. Note that, in this example, queues 24, 25 and 26 form a queue cluster. Members of a queue cluster are all assigned the same ntnQosIfQueueServiceOrder as there are tightly coupled. The ntnQosIfQueueDrainSize attribute is used to determine the additional processing characteristics of the individual queues in a cluster.

The size of the queue in bytes. Some devices set queue size in terms of packets. These devices must calculate the queue size in packets by assuming an average packet size suitable for the particular interface. Some devices have a fixed size buffer to be shared among all queues. These devices must allocate a fraction of the total buffer space to this queue calculated as the the ratio of the queue size to the sum of the queue sizes for the interface.

The object is used to restore factory default values for the ntnQosDscpToCosTable and the ntnQosCosToDscpTable. Setting the object to dscpToCos(2) will restore the ntnQosDscpToCosTable to its factory default state, and will restore the value of ntnQosMappingDscpToCosEnabled to its factory default value. Setting the object to cosToDscp(2) will restore the ntnQosCosToDscpTable to its factory default state, and will restore the value of ntnQosMappingCosToDscpEnabled to its factory default value.

A bit string representing the supported attributes of the class that is identified by the ntnQosPrcSupportSupportedPrc object. Each bit of this bit mask corresponds to a class attribute, with the most significant bit of the i-th octet of this octet string corresponding to the (8*i - 7)-th attribute, and the least significant bit of the i-th octet corresponding to the (8*i)-th class attribute. Each bit of this bit mask specifies whether or not the corresponding class attribute is currently supported, with a '1' indicating support and a '0' indicating no support. If the value of this bit mask is N bits long and there are more than N class attributes then the bit mask is logically extended with 0's to the required length.

A non-negative value indicating the maximum numbers of policy rule instances that can be installed in the identified policy rule class. Note that actual number of instances that can be installed in a PRC at any given time may be less than this value based on the current operational state (e.g., resources currently consumed) of the device.

All installed QoS policy state information can be deleted and reset to the device's default state by setting the value of this object to 'true(1)'. The value 'false(2)' will always be returned when querying this object.

The value of this attribute determines if statistics tracking is enabled for system-level policies. System-level policies are created to enforce the default QoS processing rules associated with 'trusted' and 'untrusted' interface classes. This attribute is consulted during system policy creation. Setting this object to 'disabled(1)' causes statistics tracking to be disabled for the system-level policy being created. No statistics counter resources will be consumed. Setting this attribute to 'individual(2)' causes individual counters to be allocated for each classifier that comprises the system-level policy. A value of 'aggregate(3)' causes a single statistics counter to be allocated to track data associated with all of the classifiers that comprise the system policy. The value of this attribute is consulted when a policy is created or reinstalled. This allows the filter statistics tracking to be enabled only when deemed necessary. Enumeration: 'disabled': 1, 'aggregate': 3, 'individual': 2.

Specifies the maximum amount of time, in seconds, before non-volatile QoS configuration data will be written to non-volatile storage. Delaying NV access can be used to minimize file I/O aiding agent efficiency if a large amount of QoS data is being configured.

The value of this attribute determines the queue set that is associated with all egress interfaces by default. A queue set is characterized by the number of queues in the set, how the queues are serviced, the queue weights and the buffer resources that are associated with the inidividual queues. All queue sets are defined in the ntnQosIfQueueTable. The value of this attribute is consulted when the system is initialized. Changing the value of this attribute will therefore not take effect until after the system is restarted. Enumeration: 'queueSetFour': 4, 'queueSetSeven': 7, 'queueSetTwo': 2, 'queueSetFive': 5, 'queueSetThree': 3, 'queueSetEight': 8, 'queueSetSix': 6, 'queueSetOne': 1.

The value of this attribute determines the method through which buffering resources are allocated to ports sharing a pool of buffers. The buffering resources associated with a series of ports are finite. This buffer pool may be statistically allocated to the individual ports sharing the pool or they may be allocated such that the traffic pattern dictates which ports temporarily consume the majority of the buffers. The value of this attribute determines the level of buffer sharing or over-allocation that can take place among ports sharing a buffer pool. Higher levels of over-allocation increase the likelyhood (under heavy load) of a relatively few number of ports consuming all the buffers in a pool, causing packets to be dropped on other ports due to buffer starvation. A value of 'minimumOverAllocation(1)' indicates that only a small amount of resource sharing is allowed. Greater resource sharing is allowed if the value of this attribute is 'mediumOverAllocation(2)' and the chance of over-allocation occurring is maximized by the specifying that 'maximumOverAllocation(3)' is desired. In lossless mode, the buffer allocation and thresholds are such that pause frames are generated to the endstations prior to frames being discarded due to lack of available buffers, allowing the end stattions to back off. This mode allows for lossless behavior at the expense of throughput. Lossless PFC mode operates in a similar fashion to lossless but provides the service on a per-priority (802.1p) basis. 'spb-scaled(6)' is a mode similar to 'mediumOverAllocation(2)', but optimized for scaled SPB setups. The value of this attribute is consulted when the system is initialized. Changing the value of this attribute will therefore not take effect until after the system is restarted. Enumeration: 'maximumOverAllocation': 3, 'minimumOverAllocation': 1, 'spb-scaled': 6, 'losslessPfc': 5, 'mediumOverAllocation': 2, 'lossless': 4.

Determines whether QoS Agent User Based Policy (UBP) support is enabled and, if so, what level of support is enabled. Setting the value of this attribute to 'ubpSupportDisabled(1)' will cause user information forwarded by other applications (e.g., EAP) to be ignored by the QoS Agent. A value of 'ubpSupportHighSecurityLocalData(2)' or 'ubpSupportLowSecurityLocalData(3)' will cause the internal QoS Agent database to be searched for user-specific classification data when user information is forwarded by other applications. When a high level of security is requested, user- specific classification data that is found must be successfully installed before a user is given access to the switch. A low level of security means that a user will be given access to the switch even if the resources to install user- specific classification data are not currently available. Lastly, a value of 'ubpSupportEPMData(4)' will cause notifications to be generated for Enterprise Policy Manager (EPM) consumption based on user information forwarded by other applications. Notifications will be generated for events of interest to EPM, such as user addition/deletion that is associated with User Based Policy (UBP) support. Notifications will not be generated otherwise. Note that the information that is necessary to construct and transmit a notification must also be configured for this value to be useful. Changing the value of this attribute will cause UBP data currently in-use to be lost. Enumeration: 'ubpSupportEPMData': 4, 'ubpSupportDisabled': 1, 'ubpSupportLowSecurityLocalData': 3, 'ubpSupportHighSecurityLocalData': 2.

Determines whether interface role associations are subject to loose or strict capabilities verification. Setting the value of this attribute to 'roleAssocCompatLoose(1)' means that interfaces with different capabilities may be associated with the same role. In this case, configuration issues may arise due to these differences. Setting the value to 'roleAssocCompatStrict(2)' means that only interfaces with compatible capabilities may be associated with the same role. This mode can be used to avoid configuration issues resulting from the interfaces assigned to a role not having the same underlying capabilities. Enumeration: 'roleAssocCompatStrict': 2, 'roleAssocCompatLoose': 1.

Dictates whether the DoS Attack Prevention Package (DAPP) is enabled on all applicable ports and, when enabled, if resources will be allocated to track and report on DoS attack detection. If the attribute value is 'disable(1)', DAPP support will be disabled. A value of 'enableWithoutStatusTracking(2)' will cause the DAPP support to be enabled on all ports that are DAPP-capable. No resources will be allocated to track the DoS attack detection status. No log messages and no SNMP Traps will be generated based on the DAPP support. A value of 'enableWithStatusTracking(3)' will cause resources to be verified and consumed prior to enabling DoS attack detection support on DAPP-capable ports. Support will not be enabled if adequate resources are not available. Assuming that resources are available, log messages and SNMP Traps will be generated on a per-unit basis when a DoS attack is identified by the detection logic. Enumeration: 'enableWithStatusTracking': 3, 'enableWithoutStatusTracking': 2, 'disable': 1.

DAPP minimum TCP header length allowed. Used when performing TCP fragment validation. IPv4 TCP first fragment packets will be dropped if the TCP header (IP payload) is less than this value.

DAPP maximum IPv4 ICMP length. Used when performing ICMP validation. IPv4 ICMP packets will be dropped if the length (IP payload) exceeds this value.

DAPP maximum IPv6 ICMP length. Used when performing ICMP validation. IPv6 ICMP packets will be dropped if the length exceeds this value.

Controls NT Application Mode processing. When enabled, identified NT application traffic will be given preferential treatment over non-NT application traffic. 'Mixed' mode processing will remove any special traffic markings at egress. 'Pure' mode processing will leave any special traffic markings intact at egress. Mode changes (updates to the value of this attribute) will take effect immediately. Enumeration: 'enableMixedMode': 3, 'disable': 1, 'enablePureMode': 2.

Controls overall QoS processing for the system. When enabled, all QoS functionality can be exercised by the user. When disabled, installed QoS components are temporarily removed (until the operational mode is re-enabled) and new requested QoS operations will be rejected. The QoS operational mode can not be disabled if QoS components are currently being used by non-QoS applications. If disabled, requests related to QoS components by non-QoS applications will be rejected. Note that re-enabling the QoS operational mode may result in errors if changes have been made affecting available resources while QoS was temporarily disabled. Mode changes (updates to the value of this attribute) will take effect immediately. Enumeration: 'enable': 1, 'disable': 2.

Controls filter usage related to Trusted interface class processing on platforms using filters to support treating traffic as trusted. A mode of 'partialDscpMapping(1)' causes filters to be installed that only support mapping of industry standard DSCP values. This is the default setting. A mode of 'fullDscpMapping(2)' causes filters to be installed mapping all possible DSCP values in support of Trusted interface class processing. A reset may be required for updates of this object to take effect. Enumeration: 'fullDscpMapping': 2, 'partialDscpMapping': 1.

Most installed QoS policy state information can be deleted and reset to the device's default state by setting the value of this object to 'true(1)'. QoS data that requires a system reset to take effect (e.g., ntnQosConfigDefaultQueueCfg) is not reset to a default value using this object. The value 'false(2)' will always be returned when querying this object.

All counters that are associated with QoS policies are reset to zero by setting the value of this object to 'true(1)'. The value 'false(2)' will always be returned when querying this object.

Controls the FCoE redirection service for the system. Enabling the service will initiate validation and possible reservation of the resources that are required for service activation. If resources are not available, the enable request will be rejected. Note that re-enabling the FCoE redirection service may result in errors if changes have been made affecting available resources while FCoE redirection was temporarily disabled. Mode changes (updates to the value of this attribute) will take effect immediately. Enumeration: 'enable': 1, 'disable': 2.

The 802 MAC address of the FCoE Network Controller (FNC) that is used in conjunction with the FCoE redirection service. Must be defined prior to enabling the FCoE redirection service. Changes made while the FCoE service is enabled will go into effect the next time the service is enabled.

Controls access to the FCoE Redirect functionality. A value of 'accessible(1)' indicates that the FCoE support can be accessed by an external FCoE Network Controller (FNC). A value of 'notAccessible(2)' indicates that FCoE Redirect functionality can not be accessed by an FNC using SNMP. Enumeration: 'accessible': 1, 'notAccessible': 2.

The interface index of the FCoE Network Controller (FNC) that is used in conjunction with the FCoE redirection service. Must be defined prior to enabling the FCoE redirection service. Changes made while the FCoE service is enabled will go into effect the next time the service is enabled.

Frames whose 802 DA matches the physical address specified by this object, taking into account address wildcarding as specified by the ntnQosL2AccessElemDstAddrMask object, are potentially subject to the processing guidelines that are associated with this entry through the related action class.

This object specifies the bits in a 802 destination address that should be considered when performing a 802 DA comparison against the address specified in the ntnQosL2AccessElemDstAddr object. The value of this object represents a mask that is logically and'ed with the 802 DA in received frames to derive the value to be compared against the ntnQosL2AccessElemDstAddr address. A zero bit in the mask thus means that the corresponding bit in the address always matches. The ntnQosL2AccessElemDstAddr value must also be masked using this value prior to any comparisons. The length of this object in octets must equal the length in octets of the ntnQosL2AccessElemDstAddr. Note that a mask with no bits set (i.e., all zeroes) effectively wildcards the ntnQosL2AccessElemDstAddr object.

A value of 'untagged(1)' indicates that only frames received untagged will match this classifier component. A value of 'tagged(2)' means that only frames received tagged will be considered a match. A value of 'ignore(3)' means that the presence, or lack thereof, of a VLAN tag in the received packet will not be considered when determining whether a frame matches this classifier entry. Enumeration: 'ignore': 3, 'untagged': 1, 'tagged': 2.

This object specifies the value that will be compared against the value contained in the EtherType field of an IEEE 802 frame. Example settings would include 'IP' (0x0800), 'ARP' (0x0806) and 'IPX' (0x8137). Setting the ntnQosL2AccessElemEtherType object to 0xFFFF indicates that EtherType data should not be considered during traffic classification. Note the EtherType value of 0xFFFF is reserved by IANA.

The 802.1p user priority value against which the value contained in the user priority field of a tagged 802.1 frame is compared. A test for equality is performed when determining if a match exists between the data in a data link layer frame and the value of this classifier. Setting the value of this object to 'matchAllPriorities(9)' causes all user priority values to match this attribute. This essentially makes any comparisons with regard to user priority values unnecessary. Enumeration: 'matchAllPriorities': 9, 'matchPriority3': 4, 'matchPriority2': 3, 'matchPriority1': 2, 'matchPriority0': 1, 'matchPriority7': 8, 'matchPriority6': 7, 'matchPriority5': 6, 'matchPriority4': 5.

This object specifies the Fibre Channel (FC) destination ID (D_ID) that should be used when performing stream identification.

This object identifies ingress interfaces, using an interface's ifIndex representation, to which the filter and action criteria specified in this entry should be applied.

The minimum value that the VLAN ID (VID) in a tagged packet must have in order to match this entry. The avFcoeRedirVlanIdMin value must be less than or equal to the avFcoeRedirVlanIdMax value. Setting the avFcoeRedirVlanIdMin object to 1 and the avFcoeRedirVlanIdMax to 4094 indicates that VLAN data should not be considered during traffic identification.

The maximum value that the VLAN ID (VID) in a tagged packet must have in order to match this entry. The avFcoeRedirVlanIdMax value must be greater than or equal to the avFcoeRedirVlanIdMin value. Setting the avFcoeRedirVlanIdMin object to 1 and the avFcoeRedirVlanIdMax to 4094 indicates that VLAN data should not be considered during traffic identification.

The 802.1p user priority value against which the value contained in the user priority field of a tagged 802.1 frame is compared. A test for equality is performed when determining if a match exists between the data in a data link layer frame and the value of this entry. A value of 'matchAllPriorities(9)' causes all user priority values to match this attribute. This essentially makes any comparisons with regard to user priority values unnecessary. Enumeration: 'matchAllPriorities': 9, 'matchPriority3': 4, 'matchPriority2': 3, 'matchPriority1': 2, 'matchPriority0': 1, 'matchPriority7': 8, 'matchPriority6': 7, 'matchPriority5': 6, 'matchPriority4': 5.

This object specifies the value that will be compared against the value contained in the EtherType field of an IEEE 802 frame. Example settings would include 'IP' (0x0800), 'FCoE' (0x8906) and 'FIP' (0x8914). Setting the avFcoeRedirEtherType object to 0xFFFF indicates that EtherType data should not be considered during traffic classification. Note the EtherType value of 0xFFFF is reserved by IANA.

This object specifies the Fibre Channel (FC) source ID (D_ID) that should be used when performing stream identification. Setting this attribute to it's default value indicates that S_ID data should not be used for traffic identification.

The 802 MAC address that will be used to update the destination MAC address in frames that are identified based on filter data specified in this entry.

The 802 MAC address that will be used to update the source MAC address in frames that are identified based on filter data specified in this entry.

The interface through which frames identified based on filter data specified in this entry will egress the device. An egress interface or an egress trunk must be specified. A value of 0 indicates that an egress interface has not been specified.

A label used to reference the FCoE redirect entry in a textual manner.

The storage type for this conceptual row. Conceptual rows having the value 'permanent' need not allow write-access to any columnar objects in the row. This object may not be modified if the associated status object is equal to 'active'.

The status of this conceptual row. An entry may not exist in the active state unless all objects in the entry have an appropriate value.

Counts the frames that have matched the criteria specified in this entry.

The trunk through which frames identified based on filter data specified in this entry will egress the device. An egress interface or an egress trunk must be specified. A value of 0 indicates that an egress trunk has not been specified.

Table to configure DEI support. DEI provides the user the option to set the packet color based on the CFI (used as DEI) bit in the packet 802.1Q tag. Also the user has the option to mark the packet color into the CFI bit in the 802.1Q tag.

An instance of the ntnQoSDEI class that identifies an interface options for DEI.

An index that identifies the interface index associated with this table entry.

This option allows the user to enable ingress coloring if the packets based on DEI in the 802.1Q packet tag.

This option allows the user to mark at egress the DEI bit in the 802.1Q tag if the packet is colored.

This object is used to create and delete quick policies. Setting the value to create(2) will create a quick policy based on the current values of the other object in the ntnQosQuickPolicy group. Setting the value to delete(3) will delete the quick policy identified by the current value of ntnQosQuickPolicyId. On retrieval, the value is always none(1). Enumeration: 'none': 1, 'create': 2, 'delete': 3.

This object indicates the list of ports to which the quick policy will be applied.

This object indicates the main action of the quick-policy. Enumeration: 'forward': 1, 'rate': 3, 'trtcm': 4, 'pbits': 2.

This object indicates the ID of a policy to be deleted.

The pbits value for creating a quick policy.

The rate value of the simple meter associated with a quick policy.

The type of a trtc quick policy. This object is ignored if the value of ntnQosQuickPolicyAction is not trtcm(4). Enumeration: 'blind': 1, 'aware': 2.

The CIR rate for creating a trtcm quick policy.

The PIR rate for creating a trtcm quick policy.

The QinQ type for a quick policy. Enumeration: 'ignore': 3, 'qinq2': 2, 'qinq1': 1.

The DSCP codepoint for a quick policy.

The priority value for a quick policy.

The VLAN ID for a quick policy.

The TPID value for a quick policy.

The IVID value or a quick policy.

The ITPID value for a quick policy.

The I-priority value for a quick policy.

The precedence value for a quick policy.

Indicates whether statistics should be tracked for this quick policy.

This object indicates whether QoS filter limiting is administratively enabled. Note that changes to this object are not applied to the operational state until the system is rebooted, so this value may differ from that of ntnQosFilterLimitingOperEnabled.

This object indicates whether QoS filter limiting is currently enabled. Note that this object will only change values (in response to changes to the value of ntnQosFilterLimitingOperEnabled) when the system is rebooted.

Describes the requirements for conformance to the Nortel Networks QoS Policy Evolution PIB.

QoS-related notifications.

Signifies that filter data associated with a user could not be installed in the context of local UBP support. The current UBP support level determines whether a User Policy element was created or not in this resource-exhaustion scenario.

Indicates that the DAPP support has detected an attack on the device generating this trap. A notification is generated once for each unit that contains ports on which an attack has been detected. In addition to the required slot and port data, additional ports on the unit that has experienced a DAPP-detected DoS attack may also be included in the trap.

Indicates that an event that impacts egress data that is associated with one or more FCoE Redirect entries has been detected.
