Page 18: Qos Overview
QoS Overview QoS Overview The 7210 SAS D, E are designed with QoS mechanisms on both ingress and egress to support multiple services per physical port. The 7210 SAS D, E have extensive and flexible capabilities to classify, police, shape, and mark traffic.
Page 19: Qos Policies
QoS Policies QoS Policies 7210 SAS D, E QoS policies are applied on service ingress, access ports, egress and access uplink ports and define: • Classification rules for how traffic is mapped to forwarding classes • • Forwarding class association with meters and meter parameters used for policing (rate- limiting).
Page 20 QoS policy defines both ingress and egress behavior. One network queue policy can be applied to the access uplink port. If no QoS policy is explicitly applied to a SAP or port, a default QoS policy is applied. Page 20 7210 SAS D, E OS Quality of Service Guide...
Page 21: Table 2: Qos Policy Types And Descriptions
Slope Ports • Enables or disables the high-slope, low-slope, and non-TCP parameters within the egress pool. Port scheduler Port • Defines the parameters for the port scheduler. 7210 SAS D, E OS Quality of Service Guide Page 21...

Page 24: Table 4: Default Network Qos Policy Egress Marking
For network egress, traffic remarking in the network QoS policy is always enabled for 7210 SAS E devices and can be enabled or disabled for 7210 SAS D devices. Table 5 lists the default mapping of forwarding class to Dot1p values.

Page 28: Meter Parameters
When defining the CIR for a meter, the value specified is the administrative CIR for the meter. The 7210 SAS D, E have a number of native rates in hardware that it uses to determine the operational CIR for the meter. The user has some control over how the administrative CIR is converted to an operational CIR should the hardware not support the exact CIR and PIR combination specified.
Page 29: Table 7: Administrative Rate Example
When defining the PIR for a meter, the value specified is the administrative PIR for the meter. The 7210 SAS D, E have a number of native rates in hardware that it uses to determine the operational PIR for the meter. The user has some control over how the administrative PIR is converted to an operational PIR should the hardware not support the exact CIR and PIR combination specified.
Page 30 Closest: The system identifies the next multiple of 8 kbps that is closest to the specified rate. For 7210 SAS D devices, the maximum CIR and PIR rate is 4000000. The range of CBS and MBS is 4 up to 16384.
Page 31 RFC4115. Color Aware Policing The 7210 SAS D, E support Color Aware policing at the network ingress, where as at service ingress policing is color blind. In color aware policing user can define the color of the packet using the classification and feed those colored packets to the meter.
Page 32 The profile marked by the meter is used to determine the packets eligibility to be enqueued into a buffer at the egress (when a slope policy is configured at the egress). Page 32 7210 SAS D, E OS Quality of Service Guide...
Page 33: Queue Parameters
The queue ID is used to uniquely identify the queue. The queue ID is only unique within the context of the QoS policy within which the queue is defined. On 7210 SAS D, E, the queue ID is not a user configurable entity but the queue ID is statically assigned to the 8 Queues on the port...
Page 34 The CIR for the access uplink queues are defined within network queue policies based on the forwarding class. The CIR for the access uplink queues is specified as a percentage of the network interface bandwidth. Page 34 7210 SAS D, E OS Quality of Service Guide...

Page 36: Table 8: Supported Hardware Rates And Cir/Pir Values
In 7210 SAS E devices, for the supported CIR/PIR range values 0 to 1Gb, the same hardware rate step of 64 kbps is used. In 7210 SAS D devices, for the supported CIR/PIR range values 0 to 1Gb, the same hardware rate is shown in...
Page 37 If the adaptation rule is closest, the operational CIR and PIR values will be 64 Kbps and 128 Kbps, respectively, as those are the closest matches for the administrative values that are even multiples of the 64 Kbps rate step. 7210 SAS D, E OS Quality of Service Guide Page 37...

Page 47: Buffer Pools
Buffer pools cannot be created or destroyed in the 7210 SAS. The default pools created by the system are distributed among various ports. The 7210 SAS D, E only support port egress buffer pools. The egress buffer pools are distributed as access uplink egress buffer pool and access egress buffer pools. During system initialization, based on the maximum number of ports to be supported for access and access uplink, the total buffer is distributed into the access egress buffer pool and the access uplink egress buffer pool.
Page 48: Slope Policies
By default, each pool is associated with slope-policy default which disables the high-slope and low-slope for all the queues. Access and access uplink pools are created at the port level; creation is dependent on the physical port mode (access uplink or access). Page 48 7210 SAS D, E OS Quality of Service Guide...
Page 49 By default, the high-priority, low-priority, and non-TCP RED slopes are disabled. In the 7210 SAS D, WRED is supported. WRED uses average queue lengths, queue thresholds provisioned, and drop probablility to calculate the packet’s eligibility to be enqueued. The committed portion of the buffer pool is exclusively used by a queue to enqueue traffic within committed rate.
Page 50 If the buffers are from the CBS portion of the queue, the returned buffers do not result in a change in the shared buffer utilization. Page 50 7210 SAS D, E OS Quality of Service Guide...
Page 51 RED slope. Tuning the Shared Buffer Utilization Calculation The 7210 SAS D allows tuning the calculation of the Shared Buffer Average Utilization (SBAU) after assigning buffers for a packet entering a queue as used by the RED slopes to calculate a packet’s drop probability.

Page 62: Table 21: Forwarding Class To Queue-Id Map
Forwarding-Class To Queue-ID Map There are 8 forwarding classes supported on 7210 SAS D, E. Each of these FC is mapped to a specific queue while traffic is flowing on the egress port. By mapping FC to different queues the differential treatment is imparted to various classes of traffic.
