agentCosQueueIntfShapingRate 1.3.6.1.4.1.4413.1.1.3.3.2.3.1.2
Maximum bandwidth allowed for this interface as a whole, typically used to shape the outbound transmission rate. The value is specified in terms of percentage of overall link speed for the port in 1% increments. A value of 0 means there is no maximum bandwidth limit in effect and that the interface is allowed to transmit up to its maximum line rate (i.e., work conserving method). The default value is 0. When set to a non-zero value, the interface is restricted to using at most the bandwidth specified in this object for the outbound transmission rate (i.e., non-work-conserving method). This bandwidth value is independent of any per-queue maximum bandwidth value(s) in effect for the interface, as specified in the agentCosQueueMaxBandwidth ohject, and should be considered as a second-level transmission rate control mechanism that regulates the output of the entire interface regardless of which queues originate the outbound traffic. Valid value ranges depend on the value returned by object agentCosQueueIntfShapingRateUnits. If that object returns percent(1), agentCosQueueIntfShapingRate accepts values 0..100. If that object returns kbps(2), agentCosQueueIntfShapingRate accepts values 0,64..4294967295.

agentCosQueueMgmtTypeIntf 1.3.6.1.4.1.4413.1.1.3.3.2.3.1.3
The management technique used for all queues on this interface. If taildrop(1), then all new packets presented to the queues are dropped based on some maximum threshold value(s). If wred(2), then an active queue management scheme is employed whereby packet drop precedence is considered during times of queue congestion using WRED parameters. The necessary queue management parameters are specified in the agentCosQueueMgmtTable for the corresponding agentCosQueueIntfIndex value. The default for this object is taildrop(1). Implementations that support this object but do not support weighted RED must return taildrop(1) for this value and must not allow a value of wred(2) to be set.
OBJECT-TYPE    
  INTEGER taildrop(1), wred(2)  

agentCosQueueWredDecayExponent 1.3.6.1.4.1.4413.1.1.3.3.2.3.1.4
The decay exponent value used with the weighted random early discard (WRED) algorithm to determine how quickly the average queue length calculation reacts to the current length of the queue. A higher value produces a slower response, meaning previously sampled queue length values are factored into the calculation for a longer period of time. The default value is 9. Use caution when changing this value from its default. If set too low, short traffic bursts can cause WRED to drop too many packets. If set too high, WRED might not detect queue congestion in a timely manner and becomes ineffective. The default value should be sufficient for most users. This object value is only used when the agentCosQueueMgmtType is set to wred(2) and is otherwise ignored.
OBJECT-TYPE    
  Unsigned32 0..15  

agentCosQueueDefaultsRestore 1.3.6.1.4.1.4413.1.1.3.3.2.3.1.5
Causes the default values to be restored for all COS queue objects defined for this interface. This includes objects in the following tables: agentCosQueueTable agentCosQueueMgmtTable This object always reads as disable(2). This object may only be set to enable(1), which immediately causes the default value restoration action as described above. In essence, this models a momentary-style push button switch that triggers a restoration of the original default values for all affected objects.
OBJECT-TYPE    
  INTEGER enable(1), disable(2)  

agentCosQueueIntfShapingRateUnits 1.3.6.1.4.1.4413.1.1.3.3.2.3.1.6

OBJECT-TYPE    
  SEQUENCE OF  
    AgentCosQueueEntry

agentCosQueueEntry 1.3.6.1.4.1.4413.1.1.3.3.2.4.1
Each entry describes a single class-of-service (COS) queue for a given Interface Index. The number of configurable COS queues for an interface vary based on device capabilities. All objects defined for this table entry contain a default value corresponding to a typical, non-preferential treatment of packets traversing the interface's COS queues.
OBJECT-TYPE    
  AgentCosQueueEntry  

agentCosQueueIndex 1.3.6.1.4.1.4413.1.1.3.3.2.4.1.1
The COS queue index, numbered 0 to (n-1), where n is the total number of configurable interface queues for the device as indicated by agentCosQueueNumQueuesPerPort. In general, a higher numbered queue index is used to support higher priority traffic, although actual operation may be altered via configuration through this table.
OBJECT-TYPE    
  Unsigned32  

agentCosQueueSchedulerType 1.3.6.1.4.1.4413.1.1.3.3.2.4.1.2
The type of scheduling used for this queue. If strict(1), then all traffic placed on this queue is transmitted before any queue with a lower precedence (lower agentCosQueueIndex). A weighted(2) scheme gives this queue service relative to other weighted queues based on their relative agentCosQueueMinBandwidth object values. The default is weighted(2).
OBJECT-TYPE    
  INTEGER strict(1), weighted(2)  

agentCosQueueMinBandwidth 1.3.6.1.4.1.4413.1.1.3.3.2.4.1.3
Minimum guaranteed bandwidth allotted to this queue. The value is specified in terms of percentage of overall link speed for the port in 1% increments. A value of 0 means there is no guaranteed minimum bandwidth in effect (best-effort service). The default value is 0. The sum of all agentCosQueueMinBandwidth object values for the queues on the same interface must not exceed 100%. If the agentCosQueueMaxBandwidth corresponding to the same agentCosQueueIndex on this interface is currently set to a non-zero value, then setting this object to a value greater than agentCosQueueMaxBandwidth automatically updates agentCosQueueMaxBandwidth to the same value to maintain a proper relationship between the minimum and maximum queue bandwidth specification. The value of this object is ignored when agentCosQueueSchedulerType is set to strict(1).
OBJECT-TYPE    
  Percent  

agentCosQueueMaxBandwidth 1.3.6.1.4.1.4413.1.1.3.3.2.4.1.4
Maximum bandwidth allowed for this queue, typically used to shape the outbound transmission rate. The value is specified in terms of percentage of overall link speed for the port in 1% increments. A value of 0 means there is no maximum bandwidth limit in effect and that the queue is allowed to use any available excess bandwidth (i.e., work conserving method). The default value is 0. When set to a non-zero value, the queue is restricted to using at most the bandwidth specified in this object for the outbound transmission rate (i.e., non-work-conserving method). Any non-zero value set for this object must be equal to or greater than the value of agentCosQueueMinBandwidth for the same agentCosQueueIndex on this interface.

agentCosQueueMgmtType 1.3.6.1.4.1.4413.1.1.3.3.2.4.1.5
The queue depth management technique used when per-queue specification is supported. If taildrop(1), then all new packets presented to the queue are dropped based on some maximum threshold value(s). If wred(2), then an active queue management scheme is employed whereby packet drop precedence is considered during times of queue congestion using WRED parameters. The necessary queue management parameters are specified in the agentCosQueueMgmtEntry for the corresponding agentCosQueueIntfIndex and agentCosQueueIndex values. The default for this object is taildrop(1). Implementations that do not support weighted RED must return taildrop(1) for this value and must not allow a value of wred(2) to be set.
OBJECT-TYPE    
  INTEGER taildrop(1), wred(2)  

agentCosQueueMgmtTable 1.3.6.1.4.1.4413.1.1.3.3.2.5
Table of class-of-service queue drop precedence configuration parameters. The values in this table are used based on the agentCosQueueMgmtType for the corresponding agentCosQueueIntfIndex and agentCosQueueIndex values. These parameters are specified for each drop precedence level supported within a queue.

agentCosQueueMgmtEntry 1.3.6.1.4.1.4413.1.1.3.3.2.5.1
The individual objects in this table are specified for each drop precedence level supported within a particular queue on a given interface. Each object's usage is based on the current setting of the agentCosQueueMgmtType. See the individual object descriptions for details.
OBJECT-TYPE    
  AgentCosQueueMgmtEntry  

agentCosQueueDropPrecIndex 1.3.6.1.4.1.4413.1.1.3.3.2.5.1.1
The COS queue drop precedence level, numbered 1 to p, where p is the total number of drop precedences supported per queue, as indicated by agentCosQueueNumDropPrecedenceLevels. This is used as the minor index into the table. Each supported drop precedence level for a queue has its own set of configuration parameters. The actual number of drop precedence levels supported depends on the device characteristics. For example, some implementations may allow for three levels of drop precedence (1/2/3, sometimes referred to as green/yellow/red), some may support two levels (1/2, or high/low), while others only one. Some devices use the lowest (highest-numbered) drop precedence level to represent non-TCP traffic.

agentCosQueueMgmtTailDropThreshold 1.3.6.1.4.1.4413.1.1.3.3.2.5.1.2
Tail drop queue threshold above which all packets are dropped for the current drop precedence level. The value specifies the threshold based on a fraction of the overall device queue size in terms of sixteenths (0/16, 1/16, 2/16, ... 16/16). Since device implementations vary, the actual value deployed may be rounded up or down accordingly. The default value is calculated from the agentCosQueueIndex and agentCosQueueDropPrecIndex as shown in the following table (values listed for drop precedence levels 1, 2, and 3, respectively): Queue Index 0: 16, 14, 12 Queue Index 1: 16, 14, 12 Queue Index 2: 16, 14, 12 Queue Index 3: 16, 14, 12 Queue Index 4: 16, 14, 12 Queue Index 5: 16, 14, 12 Queue Index 6: 16, 14, 12 Queue Index 7: 16, 14, 12 This object is only used when agentCosQueueMgmtType is set to taildrop(1).

The value specifies the threshold based on a fraction of the overall device queue size in terms of sixteenths (0/16, 1/16, 2/16, ... 16/16). Since device implementations vary, the actual value deployed may be rounded up or down accordingly. The default value is calculated from the agentCosQueueIndex and agentCosQueueDropPrecIndex as shown in the following table (values listed for drop precedence levels 1, 2, and 3, respectively): Queue Index 0: 8, 6, 4 Queue Index 1: 9, 7, 5 Queue Index 2: 10, 8, 6 Queue Index 3: 11, 9, 7 Queue Index 4: 12, 10, 8 Queue Index 5: 13, 11, 9 Queue Index 6: 14, 12, 10 Queue Index 7: 15, 13, 11 This object is only used when agentCosQueueMgmtType is set to wred(2).

agentCosQueueMgmtWredDropProbScale 1.3.6.1.4.1.4413.1.1.3.3.2.5.1.5
A scaling factor used for the WRED calculation to determine the packet drop probability for the current drop precedence level. The value is specified as a number S from 1-15 and is used in the formula: 1/(2** S), meaning one packet is dropped out of every (2** S). Packet dropping begins when agentCosQueueMgmtWredMinThreshold is reached and proceeds linearly up to the (2**S) value specified by this object until the agentCosQueueMgmtWredMaxThreshold is reached, beyond which all packets are dropped. Smaller values of S produce a steeper slope, hence a higher incidence of randomly dropped packets. The default value is 10, which corresponds to a drop rate of 1 out of every (2**10)=1024 packets. This object is only used when agentCosQueueMgmtType is set to wred(2).
