Page 24 QoS Overview Service egress QoS policies are applied to SAPs and map forwarding classes to service egress queues for a service. The system can allocate a maximum of 8 queues per SAP for the 8 forwarding classes. All traffic types (that is, both unicast and BUM traffic types) share the same queue on service egress.
Page 25: Slope Qos Policy Command Reference
QoS Policies used to evaluate how buffers from the pool are allocated to different FCs and to in-profile and out- of-profile traffic within a given FC. The slope policies define the WRED parameters to use for in- profile/high-priority packets and for out-of-profile/low-priority packets. The high-slope and low- slope define the parameters for in-profile/high-priority packets and for out-of-profile/low-priority packets respectively.

QoS Policies Meter Parameters Note: Only 7210 SAS-E and 7210 SAS-D supports meters on SAP ingress and access-uplink port ingress. This section describes the meter parameters that can be defined for meters provisioned on the service entities (For example: SAP ingress on 7210 SAS-D). NOTE: Not all 7210 platforms support meters for all the policies.
Page 36: Peak Information Rate
QoS Overview converted to an operational CIR should the hardware not support the exact CIR and PIR combination specified. Refer to the interpretation of the administrative CIR in Adaptation Rule for Meters on page Peak Information Rate The peak information rate (PIR) defines the maximum rate at which packets are allowed to exit the meter.

Page 38: Maximum Burst Size (For Meters/Policers)
QoS Overview Maximum Burst Size (For Meters/Policers) The maximum burst size parameter specifies the maximum burst size that can be transmitted by the source while not complying with the CIR. If the transmitted burst is lower than the MBS value then the packets is marked as out-profile by the meter to indicate that the traffic is not complying with CIR.
Page 39: Color-Aware And Color-Blind Policing/Metering
QoS Policies In srtcm mode, the meter’s the CBS and MBS token buckets are replenished at single rate, that is, CIR . In trtcm1 mode, the meter implements the policing algorithm defined in RFC2698 and trtcm2 implements the policing algorithm defined in RFC4115. The meter mode supported for different QoS policies are different.
Page 40: Qos Overrides
QoS Overview QoS Overrides The QoS Override feature support allows the user to override the meter parameters such as CBS, MBS, Rate (CIR and PIR), Mode, and Adaptation rule (CIR and PIR) at the SAP context. It is only supported for access SAPs. The values are taken from the SAP-Ingress policy, when the meter parameter values are not overridden.
Page 41: Queue Parameters
QoS Policies Queue Parameters This section describes the queue parameters provisioned for queues used in service ingress policy, service egress policy, access egress policy, network qos policy and network queue policy. NOTE: Not all 7210 platforms support queues for all the above policies. In addition, the queue parameters support available varies across different platforms.
Page 42: Peak Information Rate
QoS Overview mission rate of the queue. If the current rate is at or below the CIR threshold, the queue is considered in-profile. If the current rate is above the threshold, the queue is considered out- of-profile. The in-profile and out-profile state of queue is linked to scheduler prioritizing behavior as discussed below.
Page 43: Adaptation Rule For Queues
QoS Policies PIR for the queues of the forwarding class is defined as a percentage of the network interface bandwidth. When defining the PIR for a queue, the value specified is the administrative PIR for the queue. 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 values specified.
Page 44: Committed Burst Size
QoS Overview Hardware Rate Steps Rate Range (kbps) 64kbps 67100 - 134180 kbps 128kbps 134190 - 268360 kbps 256kbps 268370 - 536730 kpbs 512kbps 536740 - 1000000 kbps To illustrate how the adaptation rule constraints minimum, maximum and closest are evaluated in determining the operational CIR or PIR for the 7210 SAS, assume there is a queue where the administrative CIR and PIR values are 90Kbps and 150 Kbps, respectively.
Page 45: Table 10: Default Cbs And Mbs Values
QoS Policies priority forwarding class service queues, the MBS can be relatively smaller than the other forwarding class queues because the high-priority service packets are scheduled with priority over other service forwarding classes. The MBS is provisioned on ingress and egress service queues within service ingress QoS policies and service egress QoS policies, respectively.
Page 46: Queue Counters
QoS Overview Queue – Ingress Profile Assignment on 7210 SAS-K On 72120 SAS-K queues can operate in two modes – profile mode and non-profile mode. SAP Ingress queues and Access-uplink Port Ingress Queues can operate in either profile mode or non- profile mode.
Page 47: Service Ingress Qos Policies
QoS Policies • Counters for packets and octets rejected at the queue • Counters for packets and octets transmitted in-profile • Counters for packets and octets transmitted out-of-profile The counters available vary among the 7210 SAS platform. Not all the counters are supported on all the platforms.
Page 48: Figure 3: Traffic Policing And Queuing Model For Forwarding Classes
QoS Overview The required elements to define a service ingress QoS policy are: • A unique service ingress QoS policy ID. • A QoS policy scope of template or exclusive. • The number of classification and meter resources to allocate for this policy. •...
Page 49: Service Ingress Qos Policies On 7210 Sas-K
QoS Policies Service ingress QoS policy ID 1 is reserved for the default service ingress policy. The default policy cannot be deleted or changed. The default service ingress policy is implicitly applied to all SAPs which do not explicitly have another service ingress policy assigned. In the default policy, all traffic is mapped to the default forwarding class which uses a meter by default.
Page 50: Figure 4: Traffic Queuing Model For Forwarding Classes
QoS Overview Optional service ingress QoS policy elements for 7210 SAS-K include: • Additional unicast queues or multicast queues up to a total of 8. • QoS policy match criteria to map packets to a forwarding class. Each queue can have unique queue parameters to allow individual shaping of the flow mapped to the forwarding class.

Page 57 QoS Policies Step 4: Match the Dot1p value in the packet (if available) with the value configured in each of the Dot1p entry defined in the Dot1p classification policy. Assign the FC corresponding to the first entry which matches with Dot1p value in the packet. If there is no match, go to next step. Step 5: Assign the default FC.
Page 58: Hierarchical Ingress Policing
QoS Overview Hierarchical Ingress Policing Note: Hierarchical Ingress Policing supported only on 7210 SAS-D devices. Hierarchical ingress policing allows the users to specify the amount of traffic admitted into the system per SAP. It also allows the user to share the available bandwidth per SAP among the different FCs of the SAP.
Page 59 QoS Policies The subrate capabilities and per-service scheduling control are required to make multiple services per physical port possible. Without egress shaping, it is impossible to support more than one service per port. There is no way to prevent service traffic from bursting to the available port bandwidth and starving other services.

QoS Overview • CBS buffer pool • Ingress non-ring MBS pool • Egress non-ring MBS pool • Ingress ring MBS pool • Egress ring MBS pool CBS buffer pool is used to allocate buffers towards committed burst size (CBS) configured per queue for all the SAPs and access-uplink port queues and some internal system queues.
Page 65 QoS Policies are terminated. The traffic in both these directions is typically admitted into the ring after being shaped and groomed. That is in the upstream direction (that is, in the direction of customer to service edge) the SLA is enforced at service ingress points (that is, typically access SAPs) and the traffic is shaped and groomed in the downstream direction (that is, in the direction of service edge to customer) by the service edge device or the access aggregation device.
Page 66: Configuration Guidelines For Cbs And Mbs
QoS Overview • Traffic received on access-uplink SAP and sent out of another access SAP uses ring MBS buffer pool for MBS buffers on access-uplink SAP ingress and the non-ring MBS buffer pool for MBS buffers on access SAP egress. In this case, ring high-slope and ring low- slope is used on access-uplink ingress and non-ring high-slope and non-ring low-slope is used on access egress.
Page 67: Red Slopes
QoS Policies RED Slopes Operation and Configuration for 7210 SAS-E NOTE: 7210 SAS-E supports SRED mechanisms and not WRED. SRED uses the 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 68: Simplified Overview Of Red For 7210 Sas-D
QoS Overview Simplified overview of RED for 7210 SAS-D The following is a simplified overview of how a RED slope determines shared buffer availability on a packet basis: 1. The RED function keeps track of shared buffer utilization and shared buffer average utiliza- tion.
Page 69: Figure 5: Red Slope Characteristics
QoS Policies Figure 5: RED Slope Characteristics A RED slope itself is a graph with an X (horizontal) and Y (vertical) axis. The X-axis plots the percentage of shared buffer average utilization, going from 0 to 100 percent. The Y-axis plots the probability of packet discard marked as 0 to 1.
Page 70: Tuning The Shared Buffer Utilization Calculation
QoS Overview Tuning the Shared Buffer Utilization Calculation NOTE: This is not supported on 7210 SAS-E and 7210 SAS-K. 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.

Queue parameters for these 8 queues can be configured as part of the access egress QoS policy which is applied on the access ports and network queue policy which is applied on the access uplink ports. The queue ID 1 to 8 are assigned to each of the 8 queues.
Page 82: Configuration Notes
CPU Queues QoS policies can be applied to the following service types: • Epipe and VPLS → On 7210 SAS-D and 7210 SAS-E, SAP ingress policies are supported on an Epipe service access point (SAP) and VPLS SAP. → On 7210 SAS-K, SAP ingress policies and SAP egress policies are supported on an Epipe service access point (SAP) and VPLS SAP.
Page 83 Discard Eligibility Indicator (DEI) based Classification and Marking In This Section This section provides information about the Discard Eligibility Indicator (DEI) feature that describes the requirements for DEI based classification and marking for 7210 platforms. NOTE: DEI classification and marking is applicable only to 7210 SAS-D and 7210 SAS-K.
Page 84: Dei Based Classification On 7210 Sas-D
DEI based Classification on 7210 SAS-D DEI based Classification on 7210 SAS-D DEI based classification is supported on Access ports, Access-uplink ports, Network ports and Hybrid ports as applicable on 7210 SAS platforms. DEI bit in the received packet is used to determine the ingress profile for the packet.
Page 85: Dei Based Marking On 7210 Sas-D
Discard Eligibility Indicator (DEI) based Classification DEI based marking on 7210 SAS-D DEI based marking is supported on access ports, access-uplink ports and network ports. DEI bit can be used to mark the packet to carry the profile, assigned by an operator’s trusted node at the ingress to the carrier’s network, to the subsequent nodes in the network.
Page 86: Configuration Guidelines For 7210 Sas-D
Configuration Guidelines for 7210 SAS-D Configuration Guidelines for 7210 SAS-D The following are configuration Guidelines for DEI based classification and marking: • While disabling DEI based classification on a port, all the meters used by the SAPs configured on this port must be in color blind mode. The converse is also true, that is, while attaching a sap-ingress qos policy with meter as color aware to a SAP, the DEI based classification must have been enabled on the port on which SAP exists.
Page 87: Dei Based Classification On 7210 Sas-K
Discard Eligibility Indicator (DEI) based Classification DEI based Classification on 7210 SAS-K DEI based classification is supported on SAP ingress and access-uplink port ingress. DEI bit in the received packet can be used to assign the ingress profile for the packet. If in the received packet, DEI = 0, then the packet is considered to be GREEN or in-profile and if DEI = 1, then the packet is considered to be YELLOW or out-of-profile.

Overview Overview Egress port rate limiting allows the device to limit the traffic that egresses through a port to a value less than the available link bandwidth. This feature is supported on the 7210 SAS-Series platforms. Applications This feature is useful when connecting the 7210 SAS to an Ethernet-over-SDH (EoSDH) (or microwave) network, where the network allocates predetermined bandwidth to the nodes connecting into it, based on the transport bandwidth requirement.

Page 116: Overview
Overview Overview Network QoS policy has an ingress and egress component, which define the QoS processing behavior to be provided for packets that ingress the access-uplink port and egress the access- uplink port respectively. The ingress component of the policy defines how the Dot1p bits are mapped to internal forwarding class and profile state for 7210 SAS-D and 7210 SAS-E devices.
Page 117 Network QoS Policies • For packets sent out of a access-uplink port, the network QoS policy defines the marking values (for example: IEEE 802.1p bits, etc.) to use based on the forwarding class and the profile state • The default map of FC to marking values (for example: 802.1p bits) is as shown in default network qos policy, policy id 1.
Page 118: Normal Qos Operation
Overview Normal QoS Operation The following types of QoS mapping decisions are applicable on an access-uplink port. • Ethernet Dot1P value mapping (if defined) • Default QoS mapping The default QoS mapping always exists on an access uplink port and every received packet will be mapped to this default if another explicitly defined matching entry does not exist.

When enabled, the packet classified to this FC the DEI bit is used to determine the ingress profile for the packet. Packets received with DEI bit set to zero are treated as in-profile and packets with DEI bit set to one are treated as out-of- profile packets.
Page 162 Network Ingress QoS Policy Commands A maximum of eight dot1p rules are allowed on a single policy. Values 0 — 7 fc fc-name — The value given for the fc-name parameter must be one of the predefined forwarding classes in the system. Specifying the fc-name is optional. When a packet matches the rule, the forwarding class is only overridden when the fc fc-name parameter is defined on the rule.
Page 163 Operational Commands The meter must be created as multipoint. The multipoint designator cannot be defined after the meter is created. If an attempt is made to modify the command to include the multipoint keyword, an error is generated and the command will not execute. The multipoint keyword can be entered in the command line on a pre-existing multipoint meter to edit meter-id parameters.

Page 174 Network Egress QoS Policy Commands weight Syntax [no] weight weight Context config>qos>network>queue Description Platforms Supported: 7210 SAS-K. Allows users to specify 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.
Page 175 Operational Commands The actual CIR rate is dependent on the queue’s adaptation-rule parameters and the actual hardware where the queue is provisioned. Values 0 — 100 Default pir percent — Defines the percentage of the maximum rate allowed for the queue. When the rate command is executed, the PIR setting is optional.

Page 340: Overview
Overview Overview NOTE: Access egress policies are not supported on 7210 SAS-K. Instead 7210 SAS-K support service egress policies which allows for per SAP egress QoS differentiation using SAP based egress queues and shapers. An access egress policy defines the queuing for the traffic egressing on the access ports. Access- egress queue policies are used at the Ethernet port and define the bandwidth distribution for the various FC/queue traffic egressing on the Ethernet port.

Page 347: Deleting Qos Policies
Access Egress QoS Policies Deleting QoS Policies Every access Ethernet port is associated, by default, with the default access egress policy (policy- id 1). You can replace the default policy with a customer-configured policy, but you cannot entirely remove the policy from the port configuration. When you remove a non-default access egress policy, the association reverts to the default policy-id 1.

Page 370: Overview
Overview Overview The Service Egress policy defines the Service Level Agreement (SLA) for service packets as they egress on the access SAP. Service Egress QoS policies allow the definition of queue parameters along with remark policy. With the default service egress policy, the system allocates 1 (one) queue. All the 8 FCs are mapped to use the same queue.
Page 371: Configuration Guidelines For Sap Egress Policy
Service Egress Policies → Dot1p and/or IP DSCP marking must be supported on access SAP egress; Provide support for configuration of per FC Dot1p and/or IP DSCP marking, with the capability to assign different Dot1p and/or IP DSCP values for in-profile and out-of- profile packets.
Page 372 Overview • FC to queue map can be defined, this allows user to assign the packets classified into a particular FC to any one of the queues configured for the SAP. • Both unicast traffic and BUM traffic share a single queue per FC. In other words, unlike service ingress policy, it is not possible to assign different queues for BUM traffic and unicast traffic.

Page 465: Remark Policies For 7210 Sas-K Devices
Remark Policies for 7210 SAS- K devices In This Section This section provides information to configure remark policies using the command line interface. This section is applicable only to 7210 SAS-K devices. Topics in this section include: • Overview on page 448 •...
Page 466: Overview
Overview Overview The remark policies are used to configure the marking behavior for the system at the egress of access SAP or access uplink port. These policies allow the user to define the forwarding class to egress marking values and allow them to use the available hardware resources efficiently. Based on the packet encapsulation used, the remark policy allows the user to define and associate appropriate policies to service egress, and network QoS policies applied to access-uplink port.
Page 467 Remark Policies for 7210 SAS-K devices Table 48: Summary of remark policy and attachment points for 7210 SAS-K Remark Policy Qos Policy Attachment Point Packet Header Bits Marked Type dscp service egress policy Access SAP egress • IP DSCP bits in the IP header (if present) for ser- vice packets sent out of an Access SAP.
Page 468: Configuration Guideline For 7210 Sas-K
Overview Configuration Guideline for 7210 SAS-K • The 7210 SAS-K implements the marking policy only if the node adds ones or two tags or if it replaces existing one or two tags. It does not touch the VLAN tag which represents customer payload (for example, 7210 SAS-K does not implement marking for packets when forwarding traffic out of dot1q range SAP or a NULL SAP).
Page 469: Basic Configurations
Remark Policies for 7210 SAS-K devices Basic Configurations A basic remark policy must confirm to the following: • Each remark policy must have a unique policy ID. • The remark policy type must be specified. • The forwarding class to egress marking values must be specified. Creating a Remark Policy To create a new remark policy, define the following: •...

Page 473 Configuration Commands Generic Commands description Syntax [no] description description-string Context config>qos>remark Description 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.
Page 474 Operational Commands copy Syntax copy remark src-pol dst-pol [overwrite] Context config>qos Description This command copies existing remark policy entries to another remark 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.
Page 475 Remark Policy QoS Commands remark Syntax no remark policy-id remark policy-id [create] [remark-type remarking type] Context config>qos Description Platforms Supported: 7210 SAS-K. This command creates a new remark policy of the specified type. The following types of remark policies are available: •...
Page 476 Syntax [no] fc fc-name Context config>qos>remark Description This command specifies the forwarding class name and provides the context to configure the marking value for the FC. Based on the type of remark policy created, the FC command allows the user to specify the appropriate marking values. The fc command overrides the default parameters for the forwarding class to the values defined.
Page 477 Remark Policy Forwarding Class Commands de-mark-outer Syntax [no] de-mark-outer [force de-value] Context config>qos> remark-policy> fc Description This command is used to explicitly define the marking of the DEI bit of the outermost tag for fc fc- name according to the in and out of profile status of the packet. If no de-value is present, the default values are used for the marking of the DE bit: for example, 0 for in-profile packets, 1 for out-of-profile ones –...
Page 478 This command has no effect for egress packets sent out of all other non-QinQ SAPs for example: Dot1q SAP, NULL SAP, etc. Additionally, if the egress packets for fc-name are not IEEE 802.1Q or IEEE 802.1P encapsulated, this command has no effect. In other words, this command takes effect, only when the node adds 2 tags to the packet on the egress.
Page 479 dot1p-outer Syntax no dot1p-outer dot1p-outer dot1p-value Context config> qos> remark> fc> Description Platforms Supported: 7210 SAS-K. This command explicitly defines the egress IEEE 802.1P (dot1p) bits marking for fc-name. When the marking is set, all packets of fc-name that have either an IEEE 802.1Q or IEEE 802.1P encapsulation use the explicitly defined dot1p-value.
Page 480 dscp-out-profile Syntax dscp-out-profile dscp-name no dscp-out-profile Context config> qos> remark> fc Description Platforms Supported: 7210 SAS-K. This command specifies the out-of-profile DSCP name for the forwarding class. When marking is set, the corresponding DSCP value is used to mark all IP packets with out-of-profile status, on the egress of this forwarding class queue.
Page 481 When this command is used the DEI Bit is left unchanged by the egress processing if a tag exists. If a new tag is added, the DEI bit is set to 0. This variant of the command is mutually exclusive to the use of dot1p-outer command. In other words, user has a choice to use either this command or the dot1p-outer command but not both together.
Page 482 Show Commands remark-policy Syntax remark-policy [<policy-id>] [association|detail] Context show>qos Description This command displays remark policy information. Parameters The ID of the remark policy. policy-id — Displays detailed information about the remark policy. detail — Output Remark Policy Output Fields — The following table describes remark policy output fields. Label Description The ID that uniquely identifies the policy.
