Slope Policy QoS Commands
slope-policy
Syntax [no] slope-policy name
Context config>qos
Description This command enables the context to configure a QoS slope policy.
Default
slope-policy "default"
Parameters
name — The name of the slope policy.
Values
time-average-factor
Syntax time-average-factor value
no time-average-factor
Context config>qos>slope-policy
Description
This command sets a weighting factor to calculate the new shared buffer average utilization after
assigning buffers for a packet entering a queue. To derive the new shared buffer average
utilization, the buffer pool takes a portion of the previous shared buffer average and adds it to the
inverse portion of the instantaneous shared buffer utilization.
The time-average-factor command sets the weighting factor between the old shared buffer
average utilization and the current shared buffer instantaneous utilization when calculating the
new shared buffer average utilization
The TAF value applies to all high and low priority RED slopes for ingress and egress access buffer
pools controlled by the slope policy.
The no form of this command restores the default setting.
Default
7 - Weighting instantaneous shared buffer utilization is 0.8%.
Parameters
value —
specified for TAF affects the speed at which the shared buffer average utilization tracks the
instantaneous shared buffer utilization. A low value weights the new shared buffer average
utilization calculation more to the shared buffer instantaneous utilization, zero using it exclusively.
