Slope Policy QoS Policy Commands
The low-slope parameters can be changed at any time and the affected buffer pool low priority
RED slopes must be adjusted appropriately.
The no form of this command restores the low slope configuration commands to the default
values. If the leaf commands within low-slope are set to the default parameters, the low-slope
node will not appear in save config and show config output unless the detail parameter is present.
non-tcp-slope
Syntax
[no] non-tcp-slope
Context
config>qos>slope-policy>queue
Description
This command configures non-tcp profile RED slope parameters.
The no form of the command reverts to the default.
time-average-factor
Syntax
time-average-factor value
no time-average-factor
Context
config>qos>slope-policy>queue
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 ,low priority and non-tcp packets WRED slopes for egress
access and network 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 — Represents the Time Average Factor (TAF), expressed as a decimal integer. The 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
