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 is the connectionPoolCapacity attribute is set to non-zero values.

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.

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.

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

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.

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)

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.

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. Enumeration: 'on': 1, 'off': 0.

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. Enumeration: 'on': 0, 'off': 1.

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.

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.

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.

This variable represents an individual value for the mscLpAruConnUsageTable.

This attribute indicates the maximum value of the txCellFreeListSize and the discard thresholds of the transmit cell free list. The transmit cell free list is the memory used for storing ATM cells to be transmitted by the Lp. The first value indicates the maximum size of the transmit cell free list. This is derived based upon the connectionPoolCapacity and the txFrameMemoryAllocation under the ARC component. When the txCellFreeListSize decreases to the second value, the txCellFreeListCongestionState changes from 3 to 2. In congestion state 2, traffic with discard priority (DP) = 3 is discarded. This threshold is set approximately at 25 percent of the first value, the maximum transmit cell free list size. When the txCellFreeListSize decreases to the third value, the txCellFreeListCongestionState changes from 2 to 1. In congestion state 1, traffic with discard priority (DP) = 2 is discarded. This threshold is set approximately at 20 percent of the first value, the maximum transmit cell free list size. When the txCellFreeListSize decreases to the fourth value, the txCellFreeListCongestionState changes from 1 to 0. In congestion state 0, traffic with discard priority (DP) = 1 is discarded. This threshold is set approximately at 10 percent of the first value, the maximum transmit cell free list size.

An entry in the mscLpEngArcOvProvTable.

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.

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 memorys. This attribute is ignored for the 1pOC48SmSrAtm card as it does not support multicast connections. For CQC based ATM FPs, the maximum value for this attribute is 10752.

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.

This attribute specifies the fraction of the receive memory which should be allocated to the reception of cells on an FP. The remaining receive memory is allocated for the reception 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 receive memory allocated to the receive cell memory is indicated by the Arc rxCellMemoryAllocation 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.

An entry in the mscLpEngArcCqcOvProvTable.

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.

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.

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. Enumeration: 'disabled': 0, 'cardDependent': 2, 'enabled': 1.

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. Enumeration: 'aggregate': 0, 'individualQueue': 1.

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.

This attribute indicates if the reduction of the maximum Cell Delay Variation (CDV) of shaped transmit traffic is applicable. When the value of this attribute is 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 enabled, the CDV relationship changes to the following equation: CDV <= 1/ASR + 1/LS Enumeration: 'disabled': 0, 'cardDependent': 2, 'enabled': 1.

This attribute specifies the maximum number of connections (VCC, VPC and VPT) that can be configured on the AQM instance of the LogicalProcessor. The value of the attribute restricts the sum of the (maxVccs + maxVpcs +(maxVpts * 3)) across all AtmIfs bound to this AQM instance. Note that 3 connections are used for each standard Vpt and 2 for each basic Vpt. The value of this attribute should be less than than or equal to totalConnectionPoolCapacity of the Arc component. The default value derivedFromArc is obtained using the following equation: totalConnectionPoolCapacity / number of AQM component on FP. VALUES ( 0 = derivedFromArc )

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.

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. 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.

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. Enumeration: 'aggregate': 0, 'individualQueue': 1.

This attribute indicates the current availability of the transmit cell memory. The transmit cell memory is the memory available for storing ATM cells to be transmitted by the Lp.

This attribute indicates the lowest availability of the transmit cell memory. The transmit cell memory is the memory available for storing ATM cells to be transmitted by the Lp. This attribute is reset to the current availability every 15 minutes and when the card is reset.

This attribute indicates the congestion state of the transmit cell memory on this FP. The congestion state of memory is indicated by a numeric value ranging from 0 to 3. When memory is in a congested state 'x', only traffic with discard priority (DP) 0 to 'x' is processed. Traffic with DP > 'x' is discarded. Therefore, if the congestion state is 3, there is no congestion and all traffic is stored. Likewise, when the congestion state is 0, there is maximum congestion and only traffic with DP=0 is processed.

This attribute indicates the total transmit cell memory size and the discard thresholds of the transmit cell memory. The transmit cell memory is the memory used for storing ATM cells to be transmitted by the Lp. The first value indicates the total transmit cell memory size. This is derived based upon the connectionPoolCapacity value. When the txCellMemoryAvailable attribute decreases to the second value, the txCellMemoryCongestionState changes from 3 to 2. In congestion state 2, traffic with discard priority (DP) = 3 is discarded. This threshold is set approximately at 25 percent of the first value, the total transmit cell memory size. When the txCellMemoryAvailable attribute decreases to the third value, the txCellMemoryCongestionState changes from 2 to 1. In congestion state 1, traffic with discard priority (DP) >= 2 is discarded. This threshold is set approximately at 20 percent of the first value, the total transmit cell memory size. When the txCellMemoryAvailable attribute decreases to the fourth value, the txCellMemoryCongestionState changes from 1 to 0. In congestion state 0, traffic with discard priority (DP) >= 1 is discarded. This threshold is set approximately at 10 percent of the first value, the total transmit cell memory size. The opposite effect occurs when the txCellMemoryAvailable attribute increases (txCellMemoryCongestionState increases from 0 to 3 accordingly)

When memory is in a congested state 'x', only traffic with discard priority (DP) 0 to 'x' is processed. Traffic with DP > 'x' is discarded. Therefore, if the congestion state is 3, there is no congestion and all traffic is stored. Likewise, when the congestion state is 0, there is maximum congestion and only traffic with DP=0 is stored.

This attribute indicates the fraction of the receive memory which is allocated for the reception of cells on the FP. Cell memory is used for Atm Bearer Services, ATM SVCS and ATM PVCS.

When memory is in a congested state 'x', only traffic with discard priority (DP) 0 to 'x' is processed. Traffic with DP > 'x' is discarded. Therefore, if the congestion state is 3, there is no congestion and all traffic is stored. Likewise, when the congestion state is 0, there is maximum congestion and only traffic with DP=0 is stored.

This attribute indicates the total transmit cell memory size and the discard thresholds of the transmit cell memory. The transmit cell memory is the memory used for storing ATM cells to be transmitted by this FP. The first value indicates the the total transmit cell memory size. This is derived based upon the connectionPoolCapacity and the txCellMemoryAllocation attributes. When the txCellMemoryAvailable attribute decreases to the second value, the txCellMemoryCongestionState changes from 3 to 2. In congestion state 2, traffic with discard priority (DP) = 3 is discarded. This threshold is set approximately at 25 percent of the first value, the total transmit cell memory size. When the txCellMemoryAvailable attribute decreases to the third value, the txCellMemoryCongestionState changes from 2 to 1. In congestion state 1, traffic with discard priority (DP) >= 2 is discarded. This threshold is set approximately at 20 percent of the first value, the total transmit cell memory size. When the txCellMemoryAvailable attribute decreases to the fourth value, the txCellMemoryCongestionState changes from 1 to 0. In congestion state 0, traffic with discard priority (DP) >= 1 is discarded. This threshold is set approximately at 10 percent of the first value, the total transmit cell memory size. The opposite effect occurs when the txCellMemoryAvailable attribute increases (txCellMemoryCongestionState increases from 0 to 3 accordingly).

This group contains frame services provisionable engineering parameters for this LogicalProcessor. Note that altering any of these parameters will result in a card reset.

An entry in the mscLpEngFcrcOvProvTable.

This attribute indicates 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 sub-connections requested by this attribute may be allocated. The desired number of sub- connections allocated is indicated by the sum of fcrc subConnectionPoolAvailable and fcrc subConnectionPoolUsage attributes. This pool is used for connection oriented services only. Each of the following components uses one sub-connection from this pool: FrAtm/n Dlci/n Siwf McsMgr Frf5EpG/n Frf5Ep/n Lmi McsMgr Frf5EpG/n Frf5Ep/n Dlci/n When the sub-connection pool is exhausted, no more connections are accepted from the services which utilize this pool. Note: Ip Routing entries also compete for this memory. The maximum size of this pool is 8192 for CQC based cards. The default cardDependent has the effect of setting subConnectionPoolCapacity to 1024 for both CQC cards and SGAF cards. VALUES ( 65535 = cardDependent )

This attribute indicates 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. An 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/n Ep/n EpD transportConnectionPreference attribute is set to atmOnly, each instance of the McsMgr DprsMcsEpG/n Ep/n component uses one resource record from this pool, otherwise it does not use this pool. Note: Frame and Cell queues also compete for this memory. Each DPRS instance requires two resource records and each VNS instance requires one resource records from this pool. (A VNS instance is an lnn combined with a trunk). The maximum size of this pool is 256 for CQC based cards. The default cardDependent has the effect of setting lnnConnectionPoolCapacity to 128 for CQC cards and 256 for SGAF cards. VALUES ( 0 = cardDependent )

This attribute indicates the number of desired IP routing entries for the Logical Processor. It is used to determine the number of IP routing resources to be allocated on the card. Each IP routing resource can hold between one and three IP routing entries. To calculate the number of IP routing resources required, an average of 2 IP routing entries per IP routing resource is used. If there are not enough resources on the card, a smaller pool is allocated. Operational attribute (in Fcrc Pqc) ipRoutesPoolSize indicates the actual size of the pool.

This attribute indicates the current availability of the transmit frame memory (in units of frames). The transmit frame memory is the memory available for storing frames to be transmitted by this FP.

This attribute indicates the lowest availability of the transmit PQC/ CQC frame memory (in units of frames). The transmit frame memory is the memory available for storing frames to be transmitted by this FP. This value is reset every 15 minutes and when the card is reset.

This attribute indicates the congestion state of the transmit frame memory on this FP. The congestion state of memory is indicated by a numeric value ranging from 0 to 3. When memory is in a congested state 'x', only traffic with discard priority (DP) 0 to 'x' is processed. Traffic with DP > 'x' is discarded. Therefore, if the congestion state is 3, there is no congestion and all traffic is processed. Likewise, when the congestion state is 0, there is maximum congestion and only traffic with DP=0 is processed.

This attribute indicates the congestion state of the receive frame memory on this FP. The congestion state of memory is indicated by a numeric value ranging from 0 to 3. When memory is in a congested state 'x', only traffic with discard priority (DP) 0 to 'x' is processed. Traffic with DP > 'x' is discarded. Therefore, if the congestion state is 3, there is no congestion and all traffic is stored. Likewise, when the congestion state is 0, there is maximum congestion and only traffic with DP=0 is stored.

This attribute indicates the total transmit frame memory size and the discard thresholds of the transmit frame memory. The transmit frame memory is the memory (in units of frames) used for storing frames to be transmitted by this FP. The first parameter indicates the total size of the transmit frame memory. This is derived from the connectionPoolCapacity and the txCellMemoryAllocation under the ARC component. When the txFrameMemoryAvailable attribute decreases to the second value, the txFrameMemoryCongestionState changes from 3 to 2. In congestion state 2, traffic with discard priority (DP) = 3 is discarded. This threshold is set approximately at 25 percent of the first value, the total transmit frame memory size. When the txFrameMemoryAvailable attribute decreases to the third value, the txFrameMemoryCongestionState changes from 2 to 1. In congestion state 1, traffic with discard priority (DP) >= 2 is discarded. This threshold is set approximately at 20 percent of the first value, the total transmit frame memory size. When the txFrameMemoryAvailable attribute decreases to the fourth value, the txFrameMemoryCongestionState changes from 1 to 0. In congestion state 0, traffic with discard priority (DP) >= 1 is discarded. This threshold is set approximately at 10 percent of the first value, the total transmit frame memory size. The opposite effect occurs when the txFrameMemoryAvailable attribute increases (txFrameMemoryCongestionState increases from 0 to 3 accordingly).

An entry in the mscLpEngFcrcTxFrThreshTable.

This variable represents the mscLpEngFcrcTxFrThreshTable specific index for the mscLpEngFcrcTxFrThreshTable.

This variable represents an individual value for the mscLpEngFcrcTxFrThreshTable.

This attribute indicates the total received frame memory size and the discard thresholds of the receive frame memory. The receive frame memory is the memory (in units of frames) used for storing frames received by this FP. The first parameter indicates the total size of the receive frame memory. This is derived from the connectionPoolCapacity and the rxFrameMemoryAllocation under the ARC component. When the rxFrameMemoryAvailable attribute decreases to the second value, the rxFrameMemoryCongestionState changes from 3 to 2. In congestion state 2, traffic with discard priority (DP) = 3 is discarded. This threshold is set approximately at 25 percent of the first value, the total received frame memory size. When the rxFrameMemoryAvailable attribute decreases to the third value, the rxFrameMemoryCongestionState changes from 2 to 1. In congestion state 1, traffic with discard priority (DP) >= 2 is discarded. This threshold is set approximately at 20 percent of the first value, the total received frame memory size. When the rxFrameMemoryAvailable attribute decreases to the fourth value, the rxFrameMemoryCongestionState changes from 1 to 0. In congestion state 0, traffic with discard priority (DP) >= 1 is discarded. This threshold is set approximately at 10 percent of the first value, the total received frame memory size. The opposite effect occurs when the rxFrameMemoryAvailable attribute increases (rxFrameMemoryCongestionState increases from 0 to 3 accordingly).
