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.

This command copies or overwrites existing network queue QoS policies to another network queue policy ID.
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.

This command enables the context to configure a network queue policy. Network queue policies on the Ethernet port define network egress queuing.
On the 7210 SAS-K 2F1C2T, the network queue policy can be associated with access-uplink ports to define queues to be used on egress.
On the 7210 SAS-K 2F6C4T and 7210 SAS-K 3SFP+ 8C, the network queue policy can be associated with access-uplink ports and network ports to define queues to be used on egress.

This command enables the context to configure a QoS network-queue policy queue.
The user has an option to define the FC to queue map. Either one or multiple FCs can be mapped to the same queue.
The no form of this command deletes the queue.

This command defines the method used by the system to derive the operational CIR and PIR rates when the queue is provisioned in hardware. For the cir and pir parameters, the system attempts to find the best operational rate depending on the defined constraint.
The no form of this command removes any explicitly defined constraints used to derive the operational CIR and PIR created by the application of the policy. When a specific adaptation-rule is removed, the default constraints for rate and cir apply.

This command specifies the CBS value (minimum depth of the queue).
The no form of this command reverts to the default value.
32
Supported on all 7210 SAS platforms as described in this document
This command specifies the MBS value (maximum depth of the queue).
The no form of this command reverts to the default value.
512
Supported on all 7210 SAS platforms as described in this document
This command defines the queue priority. The queue priority is used by the scheduler to determine the order of service in both the within-cir loop and within-pir loop. Higher priority queues are serviced before lower priority queues.
The no form of this command reverts to the default value.

This command overrides the default slope-policy configuration for the queue. The specified slope- policy name must exist as a current slope policy name. If the slope policy does not exist, the slope-policy command will fail. If a slope policy is currently associated with a queue, the slope policy cannot be removed from the system.
The slope policy contains the ring and non-ring high and low WRED slope definitions that will be used by the queue. See Buffer Pools for more information about ring and non-ring buffer pools and slope usage.
If the slope-policy command is not executed or the no slope-policy command is executed, the default slope policy will be associated with the queue.
The no form of this command reverts the queue to the default slope policy.

This command defines the administrative PIR and the administrative CIR parameters for the queue. The PIR defines the maximum rate that the queue can transmit packets through the port. Defining a PIR does not necessarily guarantee that the queue can transmit at the intended rate. The actual rate sustained by the queue can be limited by over subscription factors or available egress bandwidth. The CIR defines the rate at which the system prioritizes the queue over other queues competing for the same bandwidth.
The rate command can be executed at anytime, altering the PIR and CIR rates for all queues created on the access ports.
The no form of this command reverts all queues created with the queue ID by association with the QoS policy to the default PIR(100), and CIR(0) parameters.
The actual CIR rate is dependent on the queue’s adaptation-rule parameters and the actual hardware where the queue is provisioned.

This command specifies the weight of the queue.
The configured weight determines the proportion of available bandwidth that is given to this queue in comparison to other queues contending for bandwidth at the same priority level.
The no form of this command reverts the weight to default.

This command displays network queue policy information.
The following output is an example of network queue information, and Table 40 describes the output fields.
Label | Description |
Policy | The policy name that uniquely identifies the policy |
Accounting | Displays whether the accounting mode is packet-based or frame-based |
Description | A text string that helps identify the policy’s context in the configuration file |
Port-Id | Displays the physical port identifier where the network queue policy is applied |
Queue | Displays the queue ID |
CIR | Displays the committed information rate |
PIR | Displays the peak information rate |
CBS | Displays the committed burst size |
FC | Displays FC to queue mapping |
