queue queue-id
config>qos>slope-policy
Supported on all 7210 SAS platforms as described in this document
Commands in this context configure the high-priority, low-priority, and non-tcp slope parameters per queue.
Specifies the ID of the queue for which the drop-rate is to be configured.
[no] high-slope
config>qos>slope-policy>queue
Supported on all 7210 SAS platforms as described in this document
This command defines the high priority RED slope graph. Each buffer pool supports a high priority RED slope for managing access to the shared portion of the buffer pool for high priority or in-profile packets.
The high-slope parameters can be changed at any time and the affected buffer pool high priority RED slopes will be adjusted appropriately.
See Table: Slope behavior (applicable to 7210 SAS-D) for information about the mapping of traffic types to use high-slope parameters on 7210 SAS-D. See Table: Slope behavior (applicable to 7210 SAS-Dxp) for information about the mapping of traffic types to use high-slope parameters on 7210 SAS-Dxp.
The no form of this command reverts the high slope configuration commands to the default values. If the commands within high-slope are set to the default parameters, the high-slope node will not appear in save config and show config output unless the detail parameter is present.
[no] low-slope
config>qos>slope-policy>queue
Supported on all 7210 SAS platforms as described in this document
This command defines the low priority RED slope graph. Each buffer pool supports a low priority RED slope for managing access to the shared portion of the buffer pool for low priority or out-of-profile packets.
The low-slope parameters can be changed at any time and the affected buffer pool low priority RED slopes must be adjusted appropriately.
See Table: Slope behavior (applicable to 7210 SAS-D) for information about the mapping of traffic types to use low-slope parameters on 7210 SAS-D. See Table: Slope behavior (applicable to 7210 SAS-Dxp) for information about the mapping of traffic types to use low-slope parameters on 7210 SAS-Dxp.
The no form of this command reverts 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.
[no] non-tcp-slope
config>qos>slope-policy>queue
7210 SAS-D
This command configures non-tcp profile RED slope parameters.
See Table: Slope behavior (applicable to 7210 SAS-D) for information about the mapping of traffic types to use non-TCP-slope parameters on 7210 SAS-D.
The no form of this command reverts to the default.
time-average-factor value
no time-average-factor
config>qos>slope-policy>queue
Supported on all 7210 SAS platforms as described in this document
This command configures 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 priority, 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 reverts the default setting.
7
Specifies the 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 shared buffer instantaneous utilization, zero using it exclusively. A high value weights the new shared buffer average utilization calculation more to the previous shared buffer average utilization value.
