egress
config>qos>network
Supported on all 7210 SAS platforms as described in this document
This command creates or edits egress policy entries that specify the FC to marking values map to be instantiated when this policy is applied to the access-uplink port.
The FC and profile state mapping to marking values (for example: IEEE 802.1p bits, etc.) bits mapping for all packets are defined in this context.
[no] fc fc-name
config>qos>network>egress
Supported on all 7210 SAS platforms as described in this document
This command specifies the FC name. The FC name represents an egress queue. The fc fc-name represents a CLI parent node that contains subcommands or parameters describing the marking criteria of packets flowing through it. The fc command overrides the default parameters for that FC to the values defined in the network default policy.
The no form of this command removes the FC to marking value association. The FC reverts to the mapping defined in the default network policy.
undefined FCs default to the configured parameters in the default network policy (policy ID 1)
Specifies the case-sensitive, system-defined FC name for which policy entries will be created.
adaptation-rule [cir adaptation-rule] [pir adaptation-rule]
no adaptation-rule
config>qos>network>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 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. See Table: Supported hardware rates and CIR and PIR values for egress queues on the 7210 SAS-D and Table: Supported hardware rates and CIR and PIR values for egress queues on the 7210 SAS-Dxp for information about supported hardware step-size rates for 7210 SAS-D and 7210 SAS-Dxp.
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.

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.

[no] slope-policy name
config>qos>network>queue
Supported on all 7210 SAS platforms as described in this document
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 fails. 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. The non-ring slopes are used by the traffic received on access SAP ingress and sent out of access SAP egress queues. The ring slopes are used by the traffic received on access-uplink port ingress and sent out of access-uplink port egress queues.
If the slope-policy command is not executed or the no slope policy command is executed, the default slope policy is associated with the queue.
The no form of the command reverts the default slope policy to the queue.
Specifies an existing slope policy name. If the slope policy name does not exist, the slope-policy command fails.
queue queue-id create
no queue
config>qos>network
Supported on all 7210 SAS platforms as described in this document
This command creates the context to modify queue parameters associated with a particular queue.
The no form of this command deletes the queue.
Specifies the ID of the queue.
Specifies that a network queue policy will be created.
rate [cir cir-percent] [pir pir-percent]
no rate
config>qos>network>queue
Supported on all 7210 SAS platforms as described in this document
This command defines the administrative Peak Information Rate (PIR) and the administrative Committed Information Rate (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 oversubscription 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 the 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 must be specified as a positive integer.
