|---|---|
| cbs |
The Committed Burst Size parameter specifies the relative amount of reserved buffer space for the specific queue, configured as a percentage of the total reserved buffer pool.
The CBS for a queue determines whether it has exhausted its reserved buffer pool space while enqueuing packets.
When the queue has exceeded its CBS it must contend with other queues for the available shared buffer space in the buffer pool.
Access to this shared pool space is controlled by the RED slope function.
type=float default=0 minimum=0 maximum=100 units=% Displayed(tab/group)=Committed Burst Size (Burst Size) |
| cir |
Specifies the committed information rate for the queue, as a percentage of the available bandwidth.
type=int default=0 minimum=0 maximum=100 units=% Displayed(tab/group)=CIR (CIR/PIR/FIR) |
| cirAdaptation |
Specifies the adaptation rule used to compute the operational CIR value.
type=qos.RateAdaptationRule default=closest Displayed(tab/group)=CIR Adaptation (CIR/PIR/FIR) |
| cirLevel |
type=qos.LevelOrDefault default=defaultLevel |
| cirWeight |
type=qos.Weight default=weight1 |
| expedite |
Specifies an internal hardware mechanism for the queue servicing priority.
When the Auto option is selected, the queue is treated in an expedited manner when all forwarding classes mapped to the queue are expedited types (nc, ef, h1 or h2).
The queue is treated in a non-expedited manner when a single non-expedited forwarding class (be, af, l1, or l2) is mapped to the queue.
When the Yes option is selected, the queue is treated in an expedited manner regardless of the forwarding class that is mapped to the queue.
When the No option is selected, the queue is treated in an non-expedited manner regardless of the forwarding class that is mapped to the queue.
type=qos.Expedite access=read-create default=auto Displayed(tab/group)=Expedite |
| fir |
Specifies the percentage of max rate allowed
type=int default=0 minimum=0 maximum=100 units=% Displayed(tab/group)=FIR (CIR/PIR/FIR) |
| firAdaptation |
Specifies the adaptation rule used to compute the operational FIR value.
type=qos.RateAdaptationRule default=closest Displayed(tab/group)=FIR Adaptation (CIR/PIR/FIR) |
| highPriority |
type=int default=-1 minimum=-1 maximum=100 units=% Displayed(tab/group)=High Priority Reserved (Burst Size) |
| hsAlternateClassPool |
Specifies whether the HS alternate class port pool buffer should be used for traffic.
type=boolean default=false Displayed(tab/group)=HS Alternate Port Class Pool (HSQ) |
| hsClassWeight |
Specifies the weight of the scheduling class
type=int default=1 minimum=1 maximum=8 Displayed(tab/group)=HS Class Weight (HSQ) |
| hsMbs |
Specifies percentage of reserved buffer space for the queue.
type=float default=100 minimum=0 maximum=100 units=% Displayed(tab/group)=HS Maximum Burst Size (HSQ) |
| hsWredQueueSlopePlcyPointer |
Specifies the name of the Slope policy to be applied for network-queue queue
type=Pointer default=Slope:_tmnx_hs_default Displayed(tab/group)=HS WRED Slope Policy (HSQ) |
| hsWrrWeight |
Specifies the Weighted Round Robin (WRR) weight which this queue should parent
into the scheduler. The weight of each queue determines how much bandwidth that
queue gets out of the total rate for the scheduling class.
type=int default=1 minimum=1 maximum=127 Displayed(tab/group)=HS WRR Weight (HSQ) |
| level |
type=qos.Level default=level1 |
| mbs |
Specifies the relative amount of reserved buffer pool space for the maximum buffer for a queue.
The MBS for a queue is used to determine whether the queue has exhausted its total allowed buffer space while enqueuing packets.
When the queue has exceeded its maximum amount of buffer space, all packets are discarded until the queue transmits a packet.
Even when a queue has not exceeded its MBS size, buffer pool space is not guaranteed. The RED slope may also force the discard of the packet.
You must set proper CBS parameter values and control CBS oversubscription to avoid queue starvation (when a queue does not receive its fair share of buffer space).
You must also properly set the RED slope parameters for the needs of the network queues.
type=float default=0 minimum=0 maximum=100 units=% Displayed(tab/group)=Maximum Burst Size (Burst Size) |
| multicast |
type=generic.TruthValue access=read-create default=false Displayed(tab/group)=Multipoint |
| networkQueuePktoffset |
Specifies the per packet byte offset for this queue.
type=int default=127 minimum=-62 maximum=127 Displayed(tab/group)=Network Queue Packet Offset |
| pir |
Specifies the peak information rate, as a percentage of available bandwidth.
On ingress, the PIR defines the maximum rate at which the queue can transmit packets through the switch fabric.
On egress, the PIR defines the maximum rate that the queue can transmit packets out an egress interface.
The specified PIR value does not guarantee that the queue can transmit at the intended rate.
The actual rate sustained by the queue can be limited by oversubscription factors or available egress bandwidth.
type=int default=100 minimum=1 maximum=100 units=% Displayed(tab/group)=PIR (CIR/PIR/FIR) |
| pirAdaptation |
Specifies the adaptation rule used to compute the operational PIR value.
type=qos.RateAdaptationRule default=closest Displayed(tab/group)=PIR Adaptation (CIR/PIR/FIR) |
| poolName |
type=string default= minimum=0 maximum=32 Displayed(tab/group)=Pool Name |
| poolObjectPointer |
type=Pointer default= |
| portAvgOverhead |
Indicates the encapsulation overhead.
type=float default=0 minimum=0 maximum=100 units=% Displayed(tab/group)=Port Average Overhead |
| portParent |
Specifies whether this queue is parented by a port-level scheduler.
type=generic.TruthValue default=false Displayed(tab/group)=Port Parent (/Port Parent) |
| portParentCirLevel |
Specifies the port priority this queue will use to receive bandwidth from the port-level scheduler for its within-cir offered load.
type=qos.LevelOrDefault default=defaultLevel Displayed(tab/group)=CIR Level (/Port Parent) |
| portParentCirWeight |
Specifies the weight this queue will use to receive bandwidth from the port-level scheduler for its within-cir offered load.
type=qos.Weight default=weight0 Displayed(tab/group)=CIR Weight (/Port Parent) |
| portParentLevel |
type=qos.Level default=level1 Displayed(tab/group)=Level (/Port Parent) |

| queueParent |
type=string access=read-only default= minimum=0 maximum=32 |
| slopePolicyPointer |
type=Pointer default=Slope:default Displayed(tab/group)=Slope Policy |
| weight |
Specifies the weight this queue will use to receive bandwidth from the port-level scheduler for its above-cir offered load.
type=qos.Weight default=weight1 |
