QueueMgmtPolicy

Queue policy supports SRED (simple RED), which is based on instantaneous queue length.
startThreshold represents the instantaneous threshold at which drop would start, it would be calculated with respect to the shared buffer space of the port



public class QueueMgmtPolicy

Properties
exceedAdminStatus Specifies the admin state for the exceed priority RED slope. If this is set to 'down', the RED slope is inactive.

type=qos.AdministrativeState
default=down
Displayed(tab/group)=Administrative State (/Exceed Slope)

exceedMaxAverage Specifies the percentage of the buffer utilized after which the drop probability is 100 percent. This implies that all packets beyond this point will be dropped.

type=int
default=55
minimum=0
maximum=100
Displayed(tab/group)=Max Average (/Exceed Slope)

exceedMaxProbability Specifies the drop probability that increases steadily from 0 at the exceedStartAverage up to the exceedMaxProbability at the exceedMaxAverage.

type=int
default=75
minimum=1
maximum=99
Displayed(tab/group)=Max Probability (/Exceed Slope)

exceedStartAverage Specifies the percentage of the buffer utilized after which the drop probability starts to rise above 0.

type=int
default=30
minimum=0
maximum=100
Displayed(tab/group)=Start Average (/Exceed Slope)

hiAdminStatus Specifies the admin state for the high priority RED slope. If this is set to 'down', the RED slope is inactive.

type=qos.AdministrativeState
default=down
Displayed(tab/group)=Administrative State (/High Slope)

hiMaxAverage Specifies percentage of the buffer utilized after which the drop probability is 100 percent. This implies that all packets beyond this point will be dropped.

type=int
default=90
minimum=0
maximum=100
Displayed(tab/group)=Max Average (/High Slope)

hiMaxProbability The drop probability increases steadily from 0 at the hiStartAverage up to the hiMaxProbability at the hiMaxAverage.

type=int
default=75
minimum=1
maximum=99
Displayed(tab/group)=Max Probability (/High Slope)

hiStartAverage Specifies the percentage of the buffer utilized after which the drop probability starts to rise above 0.

type=int
default=70
minimum=0
maximum=100
Displayed(tab/group)=Start Average (/High Slope)

highPlusAdminStatus Specifies the admin state for the high-plus priority RED slope. If the highPlusAdminStatus is set to 'down', the RED slope is inactive.

type=qos.AdministrativeState
default=down
Displayed(tab/group)=Administrative State (/High Plus Slope)

highPlusMaxAverage Specifies the percentage of the buffer utilized after which the drop probability is 100 percent. This implies that all packets beyond this point will be dropped.

type=int
default=100
minimum=0
maximum=100
Displayed(tab/group)=Max Average (/High Plus Slope)

highPlusMaxProbability Specifies the drop probability that increases steadily from 0 at the highPlusStartAverage up to the highPlusMaxProbability at the highPlusMaxAverage.

type=int
default=75
minimum=1
maximum=99
Displayed(tab/group)=Max Probability (/High Plus Slope)

highPlusStartAverage Specifies the percentage of the buffer utilized after which the drop probability starts to rise above 0.

type=int
default=85
minimum=0
maximum=100
Displayed(tab/group)=Start Average (/High Plus Slope)

loAdminStatus Specifies the admin state for the high priority RED slope

type=qos.AdministrativeState
default=down
Displayed(tab/group)=Administrative State (/Low Slope)

loMaxAverage Specifies percentage of the buffer utilized after which the drop probability is 100 percent. This implies that all packets beyond this point will be dropped.

type=int
default=75
minimum=0
maximum=100
Displayed(tab/group)=Max Average (/Low Slope)

loMaxProbability The drop probability increases steadily from 0 at the loStartAverage up to the loMaxProbability at the loMaxAverage.

type=int
default=75
minimum=1
maximum=99
Displayed(tab/group)=Max Probability (/Low Slope)

loStartAverage Specifies percentage of the buffer utilized after which the drop probability starts to rise above 0.

type=int
default=50
minimum=0
maximum=100
Displayed(tab/group)=Start Average (/Low Slope)

mbs Specifies the maximum amount of buffer space, in kilobytes, allowed for any queue associated with this queue mgmt policy.

type=int
default=6250
minimum=1
maximum=1500000
units=kbytes
Displayed(tab/group)=Maximum Burst Size (/Burst Size)

portSpeed The value of PortSpeed for which the queue-mgmt policy is optimized. It must match the configured physical speed(port>ethernet>speed) of the underlying port, not it's egress-rate(port>ethernet>egress-rate).

type=int
default=100
minimum=10
maximum=400
Displayed(tab/group)=Port Speed

scope Specifies whether the policy can be applied to a single Queues or multiple Queues. When the parameter is set to template, the policy can be applied to multiple Queues. When the parameter is set to exclusive, the policy can be applied to only a single Queues. You can reassign the policy if you remove the assignment to the original SAP.

type=acl.ItemScope
default=template
Displayed(tab/group)=Scope

timeAvgFactor Specifies the average time factor of this queue mgmt policy.

type=int
default=7
minimum=0
maximum=31
Displayed(tab/group)=Time Average Factor
