7210 SAS-T (in access-uplink mode and Network), 7210 SAS-Sx 1/10GE: standalone and standalone-VC, and 7210 SAS-Sx 10/100GE
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.

config>qos>slope-policy>queue
7210 SAS-T (in access-uplink mode and Network), 7210 SAS-Sx 1/10GE: standalone and standalone-VC, and 7210 SAS-Sx 10/100GE
This command defines the high priority Random Early Detection (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.
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

7210 SAS-T (in access-uplink mode and Network), 7210 SAS-Sx 1/10GE: standalone and standalone-VC, and 7210 SAS-Sx 10/100GE
This command defines the low priority Random Early Detection (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.
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.

7210 SAS-T (in access-uplink mode and Network), 7210 SAS-Sx 1/10GE: standalone and standalone-VC, and 7210 SAS-Sx 10/100GE
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 Time Average Factor (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 reverts to the default value.
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.
