queue queue-id
config>qos>network-queue
Supported on all 7210 SAS platforms as described in this document
This command configures a QoS network-queue policy queue.
The FCs are mapped to queues, as listed in Table: FC-to-queue ID map. Only one FC can be mapped to one queue. A queue-id value of 8 is the highest priority and a queue-id value of 1 is the lowest priority. Network queues carry both the unicast and multicast traffic and no segregation is performed. The hardware port scheduler prioritizes the queue according to the priority for each queue. High priority traffic should be mapped to high-priority FCs. Mapping traffic to high-priority FCs does not guarantee high priority treatment, because the scheduler policy can influence the relative priority among the queues.
Specifies the queue within the policy. This is a required parameter each time the queue command is executed.
adaptation-rule [cir adaptation-rule] [pir adaptation-rule]
no adaptation-rule
config>qos>network-queue>queue
Supported on all 7210 SAS platforms as described in this document
This command defines the method used by the system to derive the operational CIR and PIR settings when the queue is provisioned in hardware. For the CIR and PIR parameters individually, 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 pir and cir apply.
adaptation-rule cir closest pir closest
Specifies the adaptation rule and defines the constraints enforced when adapting the CIR rate defined using the queue queue-id rate command. The cir parameter requires a qualifier that defines the constraint used to derive the operational CIR rate for the queue. When the cir parameter is not specified, the default constraint applies. The max (maximum), min (minimum), and closest qualifiers are mutually exclusive.
Specifies the adaptation rule and defines the constraints enforced when adapting the PIR rate defined using the queue queue-id rate command. The pir parameter requires a qualifier that defines the constraint used when deriving the operational PIR rate for the queue. When the pir command is not specified, the default constraint applies. The max (maximum), min (minimum), and closest qualifiers are mutually exclusive.
[no] slope-policy name
config>qos>network-queue>queue
Supported on all 7210 SAS platforms as described in this document
This command is used to override 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 High and Low slope definitions that will be used by the queue.
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 the command restores the default slope policy to the queue.
The name parameter is required and must specify an existing slope policy name. If slope-policy-name does not exist, the slope-policy command will fail.
rate [cir cir-percent] [pir pir-percent]
no rate
config>qos>network-queue>queue
Supported on all 7210 SAS platforms as described in this document
This command defines the PIR and the CIR parameters for the queue. The PIR defines the maximum rate at which 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 any time, changing 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 and CIR parameters.
Specifies the percentage of the guaranteed rate allowed for the queue. When the rate command is executed, a valid CIR setting must be explicitly defined. When the rate command has not been executed, the default CIR of 0 is assumed. Fractional values are not allowed and must be specified as a positive integer.
The actual CIR rate is dependent on the queue’s adaptation-rule parameters and the actual hardware where the queue is provisioned.
Specifies the percentage of the maximum rate allowed for the queue. When the rate command is executed, the PIR setting is optional. When the rate command has not been executed, or the PIR parameter is not explicitly specified, the default PIR of 100 is assumed. Fractional values are not allowed and the value must be a positive integer.
