This command creates a text description stored in the configuration file for a configuration context.
The description command associates a text string with a configuration context to help identify the context in the configuration file.
The no form of this command removes any description string from the context.
Supported on all 7210 SAS platforms as described in this document
This command specifies the CBS value. The CBS is the minimum depth of the queue.
The no form of this command reverts to the default value.
Supported on all 7210 SAS platforms as described in this document
This command configures the in-profile WRED slope parameters.
The no form of this command reverts the high-slope configuration commands to the default values.
Supported on all 7210 SAS platforms as described in this document
This command configures the out-of-profile WRED slope parameters.
The no form of this command revert the low-slope configuration commands to the default values.
Supported on all 7210 SAS platforms as described in this document
This command specifies the MBS value. The MBS is the maximum depth of the queue.
The no form of this command reverts to the default value.
Supported on all 7210 SAS platforms as described in this document
This command enables the context to configure a QoS queue management policy. A set of profiles and templates are available in hardware for configuring queue parameters, such as CBS, MBS, and WRED slope parameters per queue. These profiles are available for use with multiple queues on the system. Queue management policies allow the user to define the queue parameters and allow for sharing among the queues.
The no form of this command reverts to the default value.

This command configures the time-average factor.
The value specified for the 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, where a value of zero means the shared buffer instantaneous utilization is used exclusively. A high value weights the new shared buffer average utilization calculation more to the previous shared buffer average utilization value.
The no form of the command reverts to the default value.

This command configures the scope as exclusive or template.
The no form of this command reverts the scope of the policy to the default.

This command configures the maximum average value.
The no form of this command reverts to the default value.
max-avg 90 — high slope default is 90% buffer utilization
max-avg 75 — low slope default is 75% buffer utilization
Supported on all 7210 SAS platforms as described in this document
This command configures the maximum probability value.
The no form of this command reverts to the default value.
max-avg 75 — high slope default is 75% maximum drop probability corresponding to max-avg
max-avg 75 — low slope default is 75% maximum drop probability corresponding to max-avg
Supported on all 7210 SAS platforms as described in this document
This command enables or disables the administrative status of the WRED slope.
By default, all slopes are shut down and have to be explicitly enabled (no shutdown), which implies a zero drop probability.
The no form of this command administratively enables the WRED slope.
shutdown

This command configures the starting average value.
The no form of this command reverts to the default value.
max-avg 70 — high slope default is 70% buffer utilization
max-avg 50 — low slope default is 50% buffer utilization
Supported on all 7210 SAS platforms as described in this document
This command copies the existing queue management policy entries to another queue management policy.
The copy command is a configuration level maintenance tool used to create new policies using existing policies. It also allows bulk modifications to an existing policy with the use of the overwrite keyword.
Supported on all 7210 SAS platforms as described in this document
This command displays queue management policy information.
The following output is an example of queue management policy information, and Table 47 describes the output fields.
Label | Description |
Policy | The ID that uniquely identifies the policy |
Description | A string that identifies the policy context in the configuration file |
Time Avg | The weighting between the previous shared buffer average utilization result and the new shared buffer utilization |
CBS | Displays the committed burst size |
MBS | Displays the maximum burst size |
Slope Parameters | |
Start Avg | Specifies the low-priority or high-priority RED slope position for the shared buffer average utilization value where the packet discard probability starts to increase above zero |
Max Avg | Specifies the percentage of the shared buffer space for the buffer pool at which point the drop probability becomes 1, expressed as a decimal integer |
Admin State | Up — The administrative status of the RED slope is enabled Down — The administrative status of the RED slope is disabled Specifies the low-priority or high-priority RED slope position for the maximum non-one packet discard probability value before the packet discard probability rises directly to one |
Max Prob. | Specifies the high-priority RED slope position for the maximum non-one-packet discard probability value before the packet discard probability rises directly to one |
