What Is Nortel-Magellan-Passport-AtmBaseMIB?

Nortel-Magellan-Passport-AtmBaseMIB provides the base ATM interface configuration and common virtual-channel/virtual-path management objects for Nortel's Magellan Passport wide-area switching platform. It exposes provisioning and resource-capacity data for ATM resource components, such as connection-pool capacity, multicast-branch capacity, and transmit frame-memory allocation, through row-status-controlled provisioning tables. Its monitoring value is mainly around software/resource-configuration status: administrators check whether ATM resource components are correctly provisioned and how much connection or multicast capacity remains available on a given switch card, rather than reading physical sensors. As a 'base' MIB it underlies other Magellan Passport ATM feature MIBs (e.g., VP/VC-specific and signaling MIBs) that build on its component and row-status model. It is deployed in legacy Nortel Magellan Passport ATM WAN switches used by carriers for ATM backbone and access services, typically after a Nortel-Magellan-Passport-AtmBaseMIB download is loaded into a legacy MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in Nortel-Magellan-Passport-AtmBaseMIB. 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 operator would poll lpArcProvTable/lpArcProvEntry for lpArcTotalConnectionPoolCapacity and lpArcMulticastBranchesCapacity on a given ARC (ATM Resource Component) identified by lpArcComponentName/lpArcIndex to see how much connection or multicast capacity remains before new VCs can no longer be provisioned. Checking lpArcRowStatus in lpArcRowStatusTable confirms whether a resource component is active, and a component stuck in a non-active row status would explain provisioning failures on that card.

What Can Be Monitored

lpArcProvTable	1.3.6.1.4.1.562.2.4.1.12.19.100		not-accessible	This group specifies the configuration of processor-wide ATM- specific resources on a Logical Processor running ATM services. Note that altering any of these parameters results in a card reset.
lpArcProvEntry	1.3.6.1.4.1.562.2.4.1.12.19.100.1		not-accessible	An entry in the lpArcProvTable.
U32 lpArcTotalConnectionPoolCapacity	1.3.6.1.4.1.562.2.4.1.12.19.100.1.5	Unsigned32	read-write	This attribute is migrated to the Lp/n Eng Arc Ov attribute of the same name. This attribute specifies the maximum number of connections (both VCC and VPC) that can be enabled on the LogicalProcessor. If the LogicalProcessor is associated with a card of a cardType other than one of the following: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm; the value of the attribute restricts the sum of the (maxVccs + maxVpcs) across all AtmIfs bound to this LogicalProcessor. If the LogicalProcessor is associated with a card of one of the following cardTypes: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm; the number of available connections are distributed equally across the ports on the FP. The number of connections associated to a particular port will limit the size of the Vcc space defined by the ConnMap of the AtmIf linked to the port. Furthermore, the value of this attribute is restricted based on the number of ports on the card. For one port cards, the minimum is 512, the maximum is 4096 and the value must be divisible by 256. For two port cards, the minimum is 1024, the maximum is 8192 and the value must be divisible by 512. For three port cards, the minimum is 1536, the maximum is 7680 and the value must be divisible by 768. Increasing the value of this attribute reduces the CQM memory available for cell and frame free list. This attribute must be set to 0 if the connectionPoolCapacity attribute is set to non-zero values.
U32 lpArcMulticastBranchesCapacity	1.3.6.1.4.1.562.2.4.1.12.19.100.1.6	Unsigned32	read-write	This attribute is migrated to the Lp/n Eng Arc Ov attribute of the same name. This attribute specifies the number of multicast branches that can be enabled on the Logical Processor. A multicast branch is used for cell replication on a Vcc connection whose Vcc distributionType is pointToMultipoint. A branch represent one ATM destination for the replicated cells Increasing the value of this attribute reduces the CQM memory available for the cell and frame free lists.
U32 lpArcTxFrameMemoryAllocation	1.3.6.1.4.1.562.2.4.1.12.19.100.1.10	Unsigned32	read-write	This attribute is migrated to the Lp/n Eng Arc Ov attribute txCellMemoryAllocation. It is converted from frame percentage to cell percentage by subtracting this value from 100. This attribute specifies the percentage of the transmit CQM memory which should be allocated to the transmit frame free list on the ATM-FP. The remaining transmit CQM memory is allocated to the transmit cell free list. Frame memory is used for trunks, ATM VCC testing and for inter-card communication. There is an absolute minimum quantity of frame buffers which is required by ATM software on the FP. If the value of this attribute is smaller than the absolute minimum, the ATM software will allocate the minimum required, rather than the actual number requested. The actual percentage of the transmit CQM memory allocated to the transmit frame free list is indicated by the Aru txFrameMemoryAllocation attribute. A difference between the provisioned and the operational values may exist due to the requirement for a minimum number of frame buffers or rounding during computation within the FP.
U32 lpArcRxFrameMemoryAllocation	1.3.6.1.4.1.562.2.4.1.12.19.100.1.20	Unsigned32	read-write	This attribute is migrated to the Lp/n Eng Arc Ov attribute rxCellMemoryAllocation. It is converted from frame percentage to cell percentage by subtracting this value from 100. This attribute specifies the percentage of the receive CQM memory which should be allocated to the receive frame free list on the ATM- FP. The remaining receive CQM memory is allocated to the receive cell free list. Frame memory is used for trunks, ATM VCC testing and for inter-card communication. There is an absolute minimum quantity of frame buffers which is required by ATM software on the FP. If the value of this attribute is smaller than the absolute minimum, the ATM software will allocate the minimum required, rather than the actual number requested. The actual percentage of the receive CQM memory allocated to the receive frame free list is indicated by the Aru rxFrameMemoryAllocation attribute. A difference between the provisioned and the operational values may exist due to the requirement for a minimum number of frame buffers or rounding during computation within the FP
U32 lpArcPerVcQueueInterfaces	1.3.6.1.4.1.562.2.4.1.12.19.100.1.25	Unsigned32	read-write	This attribute is migrated to the Lp/n Eng Arc Cqc Ov attribute of the same name. This attribute specifies the number of independent ports or IMA components which support shaping and per-VC queueing on the LogicalProcessor. When this attribute is not zero, at most 4 independent ports or 4 Ima virtual links are supported, regardless of whether or not traffic shaping is enabled on the associated AtmIf components. In this case only independent port instances 0-3 or Ima instances 0-3 can be supported on an associated AtmIf component. For 2 ports cards, the valid values for this attribute are 0, 1, or 2. For 3 ports cards, the valid values for this attribute are 0, 1, or 3. For 8 ports cards, the valid values for this attribute are 0, 1, 2, or 4.
OCT lpArcShapingStackAllocation	1.3.6.1.4.1.562.2.4.1.12.19.100.1.30	OCTET STRING	read-write	This attribute is migrated to the perVcQueueInterfaces attribute of the Lp/n Eng Arc Cqc Ov. Value ~0,~1,~2 is migrated to the value 0; value 0,~1,~2 is migrated to value 1; value 0,1,~2 is migrated to the value 2 and value 0,1,2 is migrated to the value 3 (for cardTypes 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm) or to the value 4 (for other cardTypes). This attribute specifies the allocation of shaping stack resources among the ports on this FP. Shaping stacks can currently be allocated on port 0, ports 0 and 1, or ports 0, 1 and 2. Allocating shaping stacks on a port allows the use of traffic shaping and per- VC queueing on that port. Description of bits: n0(0) n1(1) n2(2)
NUM lpArcShapingScalingFactor	1.3.6.1.4.1.562.2.4.1.12.19.100.1.40	FixedPoint1	read-write	This attribute is migrated to the Lp/n Eng Arc Cqc Ov attribute of the same name. This attribute specifies the scaling factor which is to be applied to all shaping rates for this ATM-FP. The scaling factor is a multiplicative factor which is applied to the chosen shaping rate to produce an actual shaping rate. For example, if a shaping rate of 25 Mbps is used with a scaling factor of 2, the actual shaping rate is 12.5 Mbps.
INT lpArcCdvAttenuation	1.3.6.1.4.1.562.2.4.1.12.19.100.1.41	INTEGER	read-write	This attribute is migrated to the Lp/n Eng Arc Cqc Ov attribute cdvReduction. This attribute enables the attenuation of the maximum Cell Delay Variation (CDV) of shaped transmit traffic. When the value of this attribute is set to off, the CDV value can be determined by the following equation: CDV <= 2/ASR + 1/LS where ASR is the Actual Shaping Rate of the connection and LS is the Link Speed of the interface. When the value of this attribute is set to on, the CDV relationship changes to the following equation: CDV <= 1/ASR + 1/LS As can be noted from the equations above, setting this attribute to on can reduce the CDV significantly. CDV attenuation may be used to conform to policers which have strict Cell Delay Variance Tolerance (CDVT). However using this function reduces the transmit bandwidth utilization of the following cards: 3pDS3Atm, 3pOC3Atm.
INT lpArcPortAggregation	1.3.6.1.4.1.562.2.4.1.12.19.100.1.42	INTEGER	read-write	This attribute is migrated to the Lp/n Eng Arc Cqc Ov attribute portCongestionPolicy. This attribute specifies whether port aggregation is turned on or off for this ATM-FP. It applies only to transmit traffic served on the common queues and does not apply to perVc queues. When port aggregation is on, the enqueue decision of cells or frames to a common queue is based upon the congestion state of the entire port to which the queue belongs. A port is defined to be as congested as the most congested queue amongst all its queues: the low, medium and high emission priority queues. Thus, for example, if the low priority queue is congested, the high priority queue will also experience discards even though the high priority queue may itself not be congested. Setting port aggregation on assures that the low priority queues are also serviced in the event of congestion. When the value of this attribute is set to off, the enqueue decision of cells or frames to a common queue is based solely upon the congestion state of that queue, not the port. This setting assures that the absolute priority of the traffic is taken into account, regardless of whether or not the lower priority queues are being served.
U32 lpArcSubConnectionPoolCapacity	1.3.6.1.4.1.562.2.4.1.12.19.100.1.43	Unsigned32	read-write	This attribute is migrated to the Lp/n Eng Fcrc Ov attribute of the same name. This attribute specifies the maximum number of sub-connections for the LogicalProcessor. A sub-connection is used for interworking the ATM services with the frame oriented services such as Frame Relay, and Path Oriented Routing System (PORS). When a frame is received at a sub- connection, the frame header is modified to be compatible with the service it is to be forwarded to. Due to limited resources, not all of the provisioned number of sub- connections may be allocated. The actual number of sub- connections allocated is indicated by the sum of Aru subConnectionPoolAvailable and Aru SubConnectionPoolUsage attributes. This pool is used for connection oriented services only. Each of the following components uses one sub-connection from this pool: FrAtm/x Dlci/y Siwf McsMgr Frf5EpG/x Frf5Ep/y Lmi McsMgr Frf5EpG/x Frf5Ep/y Dlci/z When the sub-connection pool is exhausted, no more connections will be accepted from the services which utilize this pool.
U32 lpArcLnnConnectionPoolCapacity	1.3.6.1.4.1.562.2.4.1.12.19.100.1.44	Unsigned32	read-write	This attribute is migrated to the Lp/n Eng Fcrc Ov attribute of the same name. This attribute specifies the maximum number of resource records for the connections which utilize Logical Network Number (LNN) on the LogicalProcessor. A logical network is a subset of passport modules together with a subset of trunks that interconnect those modules. It carries the traffic for a defined set of network protocols. A LNN is used to identify a logical network. The connectionless services which utilize the logical networks require some processing at the intermediate nodes. This pool is allocated at the intermediate nodes to sustain these connectionless services. Due to limited resources, not all of the provisioned number of LNN connection resource records may be allocated. The actual number of resource records allocated is indicated by the sum of Aru lnnConnectionPoolAvailable and Aru lnnConnectionPoolUsage attributes. If the McsMgr DprsMcsEpG/x Ep/y EpD transportConnectionPreference attribute is set to atmOnly, each instance of the McsMgr DprsMcsEpG/x Ep/y component uses one resource record from this pool.
lpArcConnCapTable	1.3.6.1.4.1.562.2.4.1.12.19.291		not-accessible	This attribute is migrated to the Lp/n Eng Arc Cqc Ov attribute of the same name. This attribute is provided for backward compatibility and can only be used if the LogicalProcessor is associated to a card of one of the following cardType: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm. This attribute can be used when the desired distribution of connections across ports cannot be achieved using the totalConnectionPoolCapacity attribute. This attribute defines the maximum number of connections (both VCC and VPC) that are available on each port. The entries are indexed by port number. This number limits the range of the ConnMap entries. Note that the value of this attribute must be evenly divisible by 256, and that port 2 supports at most 2560 connections, not the full 4096.

An example of a VCC not in the enabled state is a VCC with a Test subcomponent. This attribute is equal to the sum of the AtmIf Ca connectionPoolUsage attributes of AtmIfs associated with this LogicalProcessor. If the LogicalProcessor is associated with a card of cardType 4pE1Aal1 or 4pDS1Aal1, this attribute indicates the total number of Ces components associated with this LogicalProcessor.

A logical network is a subset of passport modules together with a subset of trunks that interconnect those modules. It carries the traffic for a defined set of network protocols. A LNN is used to identify a logical network. The connectionless services which utilize the logical networks require some processing at the intermediate nodes. This pool is allocated at the intermediate nodes to sustain these connectionless services. If the McsMgr DprsMcsEpG/x Ep/y EpD transportConnectionPreference attribute is set to atmOnly, each instance of the McsMgr DprsMcsEpG/x Ep/y component uses one resource record from this pool. Note, when the value of this attribute reaches zero, no more connections will be accepted for any of the services which utilize this pool. To increase the size of this pool, use the Arc lnnConnectionPoolCapacity attribute.
U32 lpAruLnnConnectionPoolUsage	1.3.6.1.4.1.562.2.4.1.12.20.100.1.110	Unsigned32	read-only	This attribute indicates the number of resource records being utilized for the connections which use Logical Network Number (LNN) on the LogicalProcessor.

U32 lpEngArcOvTotalConnectionPoolCapacity	1.3.6.1.4.1.562.2.4.1.12.23.5.2.10.1.1	Unsigned32	read-write	This attribute specifies the maximum number of connections (VCC, VPC, and VPT) that can be enabled on this FP. A standard Vpt uses 3 connections and a basic Vpt uses 2. If the LogicalProcessor is associated with a card of a cardType other than one of the following: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm; the value of the attribute restricts the sum of the (maxVccs + maxVpcs + (maxVpts * 3)) across all AtmIfs bound to this LogicalProcessor. If the LogicalProcessor is associated with a card of one of the following cardTypes: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm; the number of available connections are distributed equally across the ports on the FP. The number of connections associated to a particular port limits the size of the Vcc space which can be defined by the ConnMap of the AtmIf linked to the port. If the ConnMap component does not exist, its default settings are used for this check. Furthermore, the value of this attribute is restricted based on the number of ports on the card. For one port cards, the minimum is 512, the maximum is 4096 and the value must be divisible by 256. For two port cards, the minimum is 1024, the maximum is 8192 and the value must be divisible by 512. For three port cards, the minimum is 1536, the maximum is 7680 and the value must be divisible by 768. If the LogicalProcessor is associated with a card of one of the following cardTypes: 8pE1Atm, 8pDS1Atm, the maximum value for this attribute is 10752. For SGAF cards, the Connmap attributes are set to their default values. Increasing the value of this attribute reduces the memory available for cell and frame memory. This attribute must be set to 0 if the connectionPoolCapacity attribute of the Arc Ov component is set to non-zero values.
U32 lpEngArcOvMulticastBranchesCapacity	1.3.6.1.4.1.562.2.4.1.12.23.5.2.10.1.2	Unsigned32	read-write	This attribute specifies the number of multicast branches that can be enabled on this FP. A multicast branch is used for cell replication on a VCC connection whose Vcc distributionType is pointToMultipoint. A branch represents one ATM destination for the replicated cells. Increasing the value of this attribute reduces the memory available for the cell and frame storage. For CQC based ATM FPs, the maximum value for this attribute is 10752.
U32 lpEngArcOvTxCellMemoryAllocation	1.3.6.1.4.1.562.2.4.1.12.23.5.2.10.1.3	Unsigned32	read-write	This attribute specifies the fraction of the transmit memory which should be allocated to the transmission of cells on an FP. The remaining memory is allocated for the transmission of frames. Frame memory is used for trunks, ATM VCC testing and for inter- card communication. Cell memory is used for Atm Bearer Service, ATM SVCs and ATM PVCs. There is an absolute minimum quantity of frame buffers which is required by ATM software on the FP. If the value of this attribute is smaller than the absolute minimum, the ATM software allocates the minimum required, rather than the actual number requested. The actual percentage of the transmit memory allocated to the transmit cell memory is indicated by the Arc txCellMemoryAllocation attribute. A difference between the provisioned and the operational values may exist due to the requirement for a minimum number of frame buffers or rounding during computation within the FP.

U32 lpEngArcCqcOvPerVcQueueInterfaces	1.3.6.1.4.1.562.2.4.1.12.23.5.3.2.10.1.1	Unsigned32	read-write	This attribute specifies the number of independent ports or IMA components which support shaping and per-VC queueing on this FP. When this attribute is not zero, at most 4 independent ports or 4 Ima virtual links are supported, regardless of whether or not traffic shaping is enabled on the associated AtmIf components. In this case only independent port instances 0-3 or Ima instances 0-3 can be supported on an associated AtmIf component. For 2 ports cards, the valid values for this attribute are 0, 1, or 2. For 3 ports cards, the valid values for this attribute are 0, 1, 2 or 3. For 8 ports cards, the valid values for this attribute are 0, 1, 2, or 4.
NUM lpEngArcCqcOvShapingScalingFactor	1.3.6.1.4.1.562.2.4.1.12.23.5.3.2.10.1.2	FixedPoint1	read-write	This attribute specifies the scaling factor which is to be applied to all shaping rates for this FP. The scaling factor is an inverse factor which is applied to the chosen shaping rate to produce an actual shaping rate. For example, if a shaping rate of 25 Mbit/s is used with a scaling factor of 2, the actual shaping rate is 12.5 Mbit/s.
INT lpEngArcCqcOvCdvReduction	1.3.6.1.4.1.562.2.4.1.12.23.5.3.2.10.1.3	INTEGER	read-write	This attribute specifies the reduction of the maximum Cell Delay Variation (CDV) of shaped transmit traffic. When the value of this attribute is set to disabled, the CDV value can be determined by the following equation: CDV <= 2/ASR + 1/LS where ASR is the Actual Shaping Rate of the connection and LS is the Link Speed of the interface. When the value of this attribute is set to enabled, the CDV relationship changes to the following equation: CDV <= 1/ASR + 1/LS As can be noted from the equations above, setting this attribute to enabled can reduce the CDV significantly. CDV reduction may be used to conform to policers which have strict Cell Delay Variance Tolerance (CDVT). However using this function reduces the transmit bandwidth utilization of the following cards: 3pDS3Atm, 3pOC3Atm, 2pJ6MAtm. When the value is cardDependent, CDV reduction is disabled for cardtypes 3pDS3Atm, 3pOC3Atm, 2pJ6MAtm, 4pDS1Aal1, 4pE1Aal1 and enabled for all other cards.
INT lpEngArcCqcOvPortCongestionPolicy	1.3.6.1.4.1.562.2.4.1.12.23.5.3.2.10.1.4	INTEGER	read-write	This attribute specifies the congestion behavior of all ports on this FP. It applies only to transmit traffic served on the common queues and does not apply to per-VC queues. When the value is aggregate, the enqueue decision of cells or frames to a common queue is based upon the congestion state of the entire port to which the queue belongs. A port is defined to be as congested as the most congested queue amongst all its common queues: the low, medium and high emission priority queues. Thus, for example, if the low priority queue is congested, the high priority queue also experiences discards even though the high priority queue may itself not be congested. Setting this attribute to aggregate assures that the low priority queues are also serviced in the event of congestion. When the value of this attribute is set to individualQueue, the enqueue decision of cells or frames to a common queue is based solely upon the congestion state of that queue, not the port. This setting assures that the absolute priority of the traffic is taken into account, regardless of whether the lower priority queues are being served.
lpEngArcCqcOvConnCapTable	1.3.6.1.4.1.562.2.4.1.12.23.5.3.2.450		not-accessible	This attribute is provided for backward compatibility and can only be used if the LogicalProcessor is associated with a card of one of the following cardType: 3pE3Atm, 3pDS3Atm, 3pOC3MmAtm, 3pOC3SmAtm, 3pE1Atm, 3pDS1Atm, 2pJ6MAtm. This attribute can be used when the desired distribution of connections across ports cannot be achieved using the totalConnectionPoolCapacity attribute. This attribute defines the maximum number of connections (VCC, VPC, and VPT) that are available on each port. A basic Vpt uses 2 connections. The entries are indexed by port number. This number limits the range of the ConnMap entries. If the Connmap component does not exist, its default settings are used for this check. Note that the value of this attribute must be evenly divisible by 256, and that port 2 supports at most 2560 connections, not the full 4096. The connection pool for each port must be set to 0 if the totalConnectionPoolCapacity attribute is set to a non-zero value.

U32 lpEngArcAqmOvHighPriorityEpdOffset	1.3.6.1.4.1.562.2.4.1.12.23.5.4.2.10.1.2	Unsigned32	read-write	This attribute specifies the high priority Early Packet Discard (EPD) offset for connection queues. On ATM IP FPs a given connection queue is associated with one of eight emission priorities (EP). These include six unshaped EPs, one exclusive VBR shaper EP and one ABR/VBR shaper EP. This attribute specifies the EPD offset for the exclusive VBR shaper EP and the first four (higher priority) unshaped EPs. This offset is used to derive a connection EPD threshold for a given Congestion Control (CC) level by subtracting the offset from the All Packet Discard (APD) threshold at the same CC level. The APD thresholds are themselves derived from the transmit queue limit. The EPD threshold only applies to a connection if the txPacketWiseDiscard feature is requested. The txPacketWiseDiscard feature can be enabled only if the transmit queue limit is at least 5.71 times the EPD offset. This ensures that the derived EPD threshold will never be less than 17.5 % of the transmit queue limit. If this condition is not satisfied, txPacketWiseDiscard for the connection will be automatically disabled. Due to the above constraint, if the operator wishes to decrease the transmit queue limit and still have txPacketWiseDiscard enabled on the connection then this offset must be set to a lower value that meets the above requirement. Due to hardware granularity the actual value of the EPD offset may not match exactly the value provisioned. The actual value is displayed under the ATM Connection Administrator service category subcomponents on ATM IP FPs. This attribute does not apply to CQC FPs.
U32 lpEngArcAqmOvLowPriorityEpdOffset	1.3.6.1.4.1.562.2.4.1.12.23.5.4.2.10.1.3	Unsigned32	read-write	This attribute specifies the low priority Early Packet Discard (EPD) offset for connection queues. On ATM IP FPs a given connection queue is associated with one of eight emission priorities (EP). These include six unshaped EPs, one exclusive VBR shaper EP and one ABR/VBR shaper EP. This attribute specifies the EPD offset for the exclusive ABR/VBR shaper EP and the last two (lower priority) unshaped EPs. This offset is used to derive a connection EPD threshold for a given Congestion Control (CC) level by subtracting the offset from the All Packet Discard (APD) threshold at the same CC level. The APD thresholds are themselves derived from the transmit queue limit. The EPD threshold only applies to a connection if the txPacketWiseDiscard feature is requested. The txPacketWiseDiscard feature can be enabled only if the transmit queue limit is at least 5.71 times the EPD offset.

INT lpEngArcAqmOvPortCongestionPolicy	1.3.6.1.4.1.562.2.4.1.12.23.5.4.2.10.1.4	INTEGER	read-write	This attribute specifies the congestion behavior of all ports on this FP. It applies only to transmit traffic and does not apply to the CBR service category. When the value is aggregate, the enqueue decision of cells or frames to a queue is based upon the congestion state of the entire port to which the queue belongs. A port is defined to be as congested as the most congested queue amongst all its queues. Thus, for example, if a nrtVBR queue is congested, the rtVBR queue also experiences discards even though the rtVBR queue may itself not be congested. Setting this attribute to aggregate assures that the low priority queues are also serviced in the event of congestion. If this attribute is set to aggregate then rtVBR must not be configured to do common queueing and its emissionPriority should be set to a number numerically smaller than or equal to 3. Another impact of setting this attribute to aggregate is that the per connection queue limits for nrtVBR and UBR connections will be increased to the link pool size and their discard thresholds will be modified to be aligned with the free list discard thresholds. When the value of this attribute is set to individualQueue, the enqueue decision of cells or frames to a queue is based solely upon the congestion state of that queue, not the port. This setting assures that the absolute priority of the traffic is taken into account, regardless of whether the lower priority queues are being served. On 3pOC3SmAtm2 and 3pOC3MmAtm2 cards, if more than one override component exists, they must have the same setting for this attribute. Otherwise, setting the attribute under one override component applies to the entire card.
U32 lpEngArcAqmOvMaxVirtualLinks	1.3.6.1.4.1.562.2.4.1.12.23.5.4.2.10.1.5	Unsigned32	read-write	This attribute specifies the maximum number of virtual links that can use this AQM. Refer to the description of the operational attribute maxVirtualLinks under component Lp/n Eng Arc Aqm/n for a complete description of the effects of setting this attribute. On all card types except 3pE3Atm2, this attribute may be set to any of the valid values. On 3pE3Atm2 cards this attribute may only be set to sameNumberAsPorts, 14, or 29, since, due to hardware considerations, there is no advantage to setting the value to 6, and there are advantages to not doing so.

A value of minimum indicates the granularity is as small as possible for the specific card on which the Aqm component resides. A value of DS1, E1, or JT2 indicates that the VL bandwidths should be allocated in multiples of the DS1, E1, or JT2 cell rates (nominally 3622 cell/s, 4528 cell/s, and 14490 cell/ s respectively).

G32 lpEngArcAqmTxCellMemoryCongestionState	1.3.6.1.4.1.562.2.4.1.12.23.5.4.10.1.7	Gauge32	read-only	This attribute indicates the congestion state of the transmit cell memory for the ATM Queue Manager (AQM) ASIC on this FP. This attribute indicates which txCellMemoryThresholds corresponds to the current value of txCellMemoryUsage. The congestion state is used to determine if cells of a particular discard priority (DP) are discarded before being queued for transmit. The congestion state of transmit cell memory is indicated by a numeric value ranging from 3 to 0. When transmit cell memory is in congestion state 'x', traffic with DP > 'x' is discarded before transmit. Traffic with DP < 'x' may be queued for transmit, depending on the congestion level of the connection transmit queue. Traffic with DP = 'x' may be either queued or discarded depending on how close the value of txCellMemoryUsage is to the next threshold as displayed in txCellMemoryThresholds. For example, CLP1 traffic is queued until the value indicated by txCellMemoryUsage equals the value indicated in txCellMemoryThresholds 3. At that point, CLP1 traffic is discarded.

U32 lpEngArcAqmMaxVirtualLinks	1.3.6.1.4.1.562.2.4.1.12.23.5.4.10.1.10	Unsigned32	read-only	This attribute indicates the maximum number of virtual links (VLs) that can exist on this AQM. Normally a virtual link contains all VCCs and VPCs provisioned for a port (OC-3, DS3, E3, etc), making a virtual link equivalent to a port. However, if an AtmIf linked to a port has provisioned virtual path terminations (VPTs) with a vptType of virtualLink, then there is one virtual link per VL VPT, and one virtual link for all remaining VCCs and VPCs not part of a VL VPT. Unless this attribute is overridden in the optional Override subcomponent, its value will be sameNumberAsPorts, indicating that there is one virtual link per port using the AQM. The value of maxVirtualLinks may restrict the maximum bandwidth allowed per virtual link. If the value of this attribute is sameNumberAsPorts there is no restriction on a virtual link's bandwidth; it may be any cell rate up to the port's link rate. If maxVirtualLinks is set to some other value, then all virtual links on the AQM are subject to a maximum cell rate, listed in the table below, which may be less than the port cell rate. maxVirtualLinks : cell rate 6: 163840 cell/s 14 : 81920 cell/s 29: 40960 cell/s On 2pOC3MmAtm2 and 2pOC3SmAtm2 cards, there is one AQM per port. Since one link is required for connections not part of a VL VPT, if maxVirtualLinks is 6 (for example), then up to fiveVL VPTs may be provisioned on the port. Continuing this example, each VPT's provisioned bandwidth can be no larger than 163840 cells/s (46% of the total OC-3 rate) and the total bandwidth available to independent VCCs and non VL VPTs will be no greater than 163840 cell/s. On 3pDS3Atm2 and 3pE3Atm2 cards, there is one AQM for the card. Since three links are required for connections not part of a VL VPT (one per port), if maxVirtualLinks is 6 (for example), then up to threeVL VPTs may be provisioned on the card. In this case, since the maximum cell rate per virtual link is 163840 cell/s, which is greater than the port cell rate for both DS3 and E3, there is no restriction on the bandwidth assigned to VL VPTs or available to independent VCC and non VL VPT connections.

U32 lpEngArcAqmVirtualLinkUsage	1.3.6.1.4.1.562.2.4.1.12.23.5.4.10.1.11	Unsigned32	read-only	This attribute indicates the number of virtual links in use on this AQM. Its maximum value is the value of operational attribute maxVirtualLinks. Since each port uses one virtual link, if maxVirtualLinks has value sameNumberAsPorts then virtualLinkUsage will be 1 for 2pOC3MmAtm2 and 2pOC3SmAtm2 cards, and 3 for 3pDS3Atm2 and 3pE3Atm2 cards.
U32 lpEngArcAqmVirtualLinkGranularity	1.3.6.1.4.1.562.2.4.1.12.23.5.4.10.1.12	Unsigned32	read-only	This attribute indicates the granularity on which virtual link bandwidths are allocated. It is affected by the Override subcomponent's provisionable virtualLinkGranularity attribute, and will vary between 562 cell/s (minimum granularity for an E3 G.751 PLCP link) and 353207 cell/s (maximum granularity for an OC-3 link).
lpEngArcAqmTxCellThreshTable	1.3.6.1.4.1.562.2.4.1.12.23.5.4.448		not-accessible	This attribute is a vector which indicates the size and three discard thresholds for transmit cell memory for the ATM Queue Manager (AQM) ASIC on this FP. Transmit cell memory is used for storing ATM cells to be transmitted by connections. It includes all cells in all connections at all service categories. The first value indicates the transmit cell memory size. It is the amount of transmit memory which is available for cell queueing, after the amount of memory specified by connectionPoolCapacity. The current value of txCellMemoryUsage together with the vector of values in txCellMemoryThresholds determines the txCellMemoryCongestionState. The congestion state determines whether cells of a given discard priority (DP) are discarded or queued for transmit. When the txCellMemoryUsage attribute is between threshold 0 and threshold 1, the txCellMemoryCongestionState indicates the value 0. In congestion state 0, traffic with DP > 0 is discarded. Threshold 1 is set approximately at 90 percent of threshold 0, the total transmit cell memory size. When the txCellMemoryUsage attribute is between threshold 1 and threshold 2, the txCellMemoryCongestionState indicates the value 1. In congestion state 1, traffic with DP > 1 is discarded. Threshold 2 is set approximately at 85 percent of threshold 0, the total transmit cell memory size. When the txCellMemoryUsage attribute is between threshold 2 and threshold 3, the txCellMemoryCongestionState indicates the value 2. In congestion state 2, traffic with DP > 2 is discarded. Threshold 3 is set approximately at 75 percent of threshold 0, the total transmit cell memory size. When the txCellMemoryUsage attribute is below threshold 3, the txCellMemoryCongestionState indicates the value 3. In congestion state 3, traffic with DP=3 is queued.

The transmit frame memory is used for storing frames to be transmitted by this FP. The first value indicates the transmit frame memory size. This is derived based on the total transmit memory capacity of this FP, and the number of connections specified. The current value of txFrameMemoryUsage together with the vector of values in txFrameMemoryThresholds determines the txFrameMemoryCongestionState. The congestion state determines whether frames of a given discard priority (DP) are discarded or queued for transmit. When the txFrameMemoryUsage attribute is between threshold 0 and threshold 1, the txFrameMemoryCongestionState indicates the value 0. In congestion state 0, traffic with DP > 0 is discarded. Threshold 1 is set approximately at 90 percent of threshold 0, the total transmit frame memory size. When the txFrameMemoryUsage attribute is between threshold 1 and threshold 2, the txFrameMemoryCongestionState indicates the value 1. In congestion state 1, traffic with DP > 1 is discarded. Threshold 2 is set approximately at 85 percent of threshold 0, the total transmit frame memory size. When the txFrameMemoryUsage attribute is between threshold 2 and threshold 3, the txFrameMemoryCongestionState indicates the value 2. In congestion state 2, traffic with DP > 2 is discarded. Threshold 3 is set approximately at 75 percent of threshold 0, the total transmit frame memory size. When the txFrameMemoryUsage attribute is below threshold 3, the txFrameMemoryCongestionState indicates the value 3. In congestion state 3, traffic with DP=3 is queued.

lpEngFcrcRxFrThreshTable	1.3.6.1.4.1.562.2.4.1.12.23.6.446		not-accessible	This attribute is a vector which indicates the size and three discard thresholds for receive frame memory for this FP. The receive frame memory is used for storing frames received by this FP. The first value indicates the total receive frame memory size. This is derived based on the total receive memory capacity of this FP, and the number of connections specified. The current value of rxFrameMemoryUsage together with the vector of values in rxFrameMemoryThresholds determines the rxFrameMemoryCongestionState. The congestion state determines whether frames of a given discard priority (DP) are discarded or queued for processing. When the rxFrameMemoryUsage attribute is between threshold 0 and threshold 1, the rxFrameMemoryCongestionState indicates the value 0. In congestion state 0, traffic with DP > 0 is discarded. Threshold 1 is set approximately at 90 percent of threshold 0, the total receive frame memory size. When the rxFrameMemoryUsage attribute is between threshold 1 and threshold 2, the rxFrameMemoryCongestionState indicates the value 1. In congestion state 1, traffic with DP > 1 is discarded.
