Page 16: Qos Overview
The operational theory of a service tunnel is that the encapsulation of the data between the two Alcatel Lucent service routers appear like a Layer 2 path to the service data although it is really traversing an IP or IP/MPLS core. The tunnel from one edge device to the other edge device is provisioned with an encapsulation and the services are mapped to the tunnel that most appropriately supports the service needs.
Page 17: Qos Policies
QoS Policies QoS Policies 7210 SAS 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 18 QoS Overview and marks the traffic accordingly. The FCs are mapped onto the queues. There are 8 queues at the port level. FC-to-queue mapping is static and is not configurable. The number of queues are static and there are always 8 queues at the port level. An access egress policy also defines how to remark the forwarding class to IEEE 802.1p bits in the customer traffic.

Page 20: Service And Network Qos Policies
QoS Overview Service and Network QoS Policies The QoS mechanisms within the 7210 SAS E are specialized for the type of traffic on the interface. For customer interfaces, there is service ingress and access egress traffic, and for access uplink interfaces, there is network ingress and network egress traffic (Figure Access Uplink Access...
Page 21: Network Qos Policies
QoS Policies Network QoS Policies Network QoS policies define ingress forwarding class meters and maps traffic to those meters for access uplink ports. When a network QoS policy is created, it always has two meters defined that cannot be deleted, one for the all unicast traffic and one for all multipoint traffic. These meters exist within the definition of the policy.

QoS Overview network. If the profile state is marked in the service core packets, out-of-profile packets are preferentially dropped over in-profile packets at congestion points in the core network. For network egress, traffic remarking in the network QoS policy is always enabled. Table 4 lists the default mapping of forwarding class to Dot1p values.

Page 24: Network Queue Qos Policies
QoS Overview Network Queue QoS Policies Network queue policies define the network forwarding class queue characteristics. Network queue policies are applied on egress on access uplink ports. There are 8 queues available at the port and FCs are mapped to these 8 queues. All policies will use eight queues like the default network queue policy.

Page 26: Meter Parameters
QoS Overview Meter Parameters This section describes the meter parameters provisioned on access and network meters provisioned on access uplinkfor QoS. The meter parameters are: • Meter ID on page 26 • Committed Information Rate on page 26 • Peak Information Rate on page 27 •...
Page 27 QoS Policies Peak Information Rate The peak information rate (PIR) defines the maximum rate at which packets are allowed to exit the meter. It does not specify the maximum rate at which packets may enter the meter; this is governed by the meter's ability to absorb bursts and is defined by its maximum burst size (MBS).
Page 28: Table 6: Administrative Rate Example
QoS Overview Table 6: Administrative Rate Example Administrative Rate Operation Rate Operation Rate Operation Rate (Min) (Max) (Closest) 1275 If user has configured any value greater than 0 and less than 64 then operation rate configured on hardware would be 64 kbps irrespective of the constraint used. Committed Burst Size The committed burst size parameter specifies the maximum burst size that can be transmitted by the source at the CIR while still complying with the CIR.
Page 29 QoS Policies Meter Counters The 7210 SAS E maintains following counters for meters within the system for granular billing and accounting. Each meter maintains the following counters: • Counters for packets or octets marked as in-profile by meter • Counters for packets or octets marked as out-of-profile by meter Meter Modes The 7210 SAS E supports following meter modes: •...
Page 30: Queue Parameters

Page 31 QoS Policies When defining the CIR for a queue, the value specified is the administrative CIR for the queue. 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. The interpretation of the administrative CIR is discussed below in Adaptation Rule on page 33 Although the 7210 SAS is flexible in how the CIR can be configured, there are conventional...
Page 32 QoS Overview Peak Information Rate The peak information rate (PIR) defines the maximum rate at which packets are allowed to exit the queue. It does not specify the maximum rate at which packets may enter the queue; this is governed by the queue's ability to absorb bursts. The actual transmission rate of a egress queue depends on more than just its PIR.
Page 33: Table 7: Supported Hardware Rates And Cir/Pir Values
QoS Policies Adaptation Rule The adaptation rule provides the QoS provisioning system with the ability to adapt specific CIR and PIR defined administrative rates to the underlying capabilities of the hardware the queue will be created on to derive the operational rates. The administrative CIR and PIR rates are translated to actual operational rates enforced by the hardware queue.
Page 34 QoS Overview 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. Committed Burst Size The committed burst size (CBS) parameter specifies the amount of buffers that can be drawn from the reserved buffer portion of the queue’s buffer pool.
Page 35: Service Ingress Qos Policies
QoS Policies Service Ingress QoS Policies Service ingress QoS policies define ingress service forwarding class meters and map flows to those meters. When a service ingress QoS policy is created, it always has two meters defined that cannot be deleted: one for the all traffic and one for all multipoint traffic. These meters exist within the definition of the policy.

Page 40: Access Egress Qos Policies
QoS Overview Access Egress QoS Policies An access egress policy defines the queue and marking characteristics for the traffic egressing towards the customer on the access ports. There are 8 queues always available at the access port and FCs are mapped into these 8 Queues. By configuring appropriate queue shape rates the individual FC traffic can be managed so that each FC traffic is well within SLA limits and does not impact the serviceability of other FCs.

Page 43: Buffer Pools
QoS Policies Buffer Pools Buffer pools cannot be created or destroyed in 7210 SAS. The default pools created are distributed among various ports. The 7210 SAS E only supports port egress buffer pools. The egress buffer pools are distributed as access uplink egress buffer pool and access egress buffer pools.
Page 44: Slope Policies
QoS Overview Slope Policies The available buffer space is partitioned into buffer pools. The buffers for a queue are allocated from a single buffer pool. Buffer pools are created for access port egress and access uplink port egress. Slope policies define the RED slope characteristics as a percentage of pool size for the pool on which the policy is applied.
Page 45 QoS Policies RED Slopes Operation and Configuration Each buffer pool supports a high-priority RED slope and a low-priority RED slope. The high- priority RED slope manages access to the shared portion of the buffer pool for high-priority or in- profile packets. The low-priority RED slope manages access to the shared portion of the buffer pool for low-priority or out-of-profile packets.
Page 46: Slope Policy Parameters
QoS Overview Slope Policy Parameters The elements required to define a slope policy are: • A unique policy ID • The high and low RED slope shapes for the buffer pool: start-threshold, drop-rate per egress queue settings for the high-priority and low-priority RED slopes. A slope policy is defined with generic parameters so that it is not inherently an access nor an access uplink policy.

Page 48: Port Scheduler Policies
QoS Overview Port Scheduler Policies Port scheduler policies control the traffic behavior on a per-port basis. Associated with each egress port is a set of eight class of service (CoS) queues and a default port-scheduler-policy named “default”. This default policy makes the port to behave in strict mode. The default policy cannot be modified.
Page 49 QoS Policies Displayed in Table 17, CoS queues 7 and 6 each have a minimum bandwidth specification of 10 Mbps, whereas the remaining QoS queues have a minimum bandwidth specification of 50 Mbps. All CoS queues have a maximum bandwidth specification of 1 Gbps. The goal of these settings is to guarantee the minimum bandwidth settings for each of the queues while also allowing each CoS queue to fully use the egress port capability by having the maximum bandwidth setting at 1 Gbps.
Page 50: Cpu Queues
QoS Overview CPU Queues The packets that are destined to the CPU are prioritized based on the application. Some of the applications that are prioritized are Layer 2 learn packets, EFM/CFM/STP/LACP packets, and Layer 3 packets. The CPU provides eight queues from BE (0) to NC (7). The packets destined to the CPU are classified internally and are put into the correct queue.
Page 51: Forwarding Classes
QoS Policies Forwarding Classes 7210 SAS devices support multiple forwarding classes and class-based queuing, so the concept of forwarding classes is common to all of the QoS policies. Each forwarding class (also called Class of Service (CoS)) is important only in relation to the other forwarding classes.
Page 52: Table 19: Forwarding Class To Queue-Id Map
QoS Overview Forwarding-Class To Queue-ID Map There are 8 forwarding classes supported on 7210 SAS 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.
Page 53: Qos Policy Entities
QoS Policies QoS Policy Entities Services are configured with default QoS policies. Additional policies must be explicitly created and associated. There is one default service ingress QoS policy, one default access egress QoS policy, one default network QoS policy and one default port scheduler policy. Only one ingress QoS policy and one egress QoS policy can be applied to a SAP or access/access-uplink port.
Page 54: Configuration Notes
Configuration Notes Configuration Notes The following information describes QoS implementation caveats: • Creating additional QoS policies is optional. • Default policies are created for service ingress, access egress, network, network-queue, slope, and port scheduler. • Associating a service or access/access uplink ports with a QoS policy other than the default policy is optional.

Page 56: Overview
Overview Overview The network QoS policy consists of an ingress and egress component. The ingress component of the policy defines how Dot1p bits are mapped to internal forwarding class and profile state. The forwarding class and profile state define the Per Hop Behavior (PHB) or the QoS treatment through the 7210 SAS.
Page 57: Normal Qos Operation
Network QoS Policies Normal QoS Operation The following types of QoS mapping decisions are applicable on a network ingress IP interface • Ethernet Dot1P value mapping (if defined) • Default QoS mapping The default QoS mapping always exists on an ingress access uplink port and every received packet will be mapped to this default if another explicitly defined matching entry does not exist.
Page 58: Dscp Marking Cpu Generated Traffic
Overview DSCP Marking CPU Generated Traffic Specific DSCP, forwarding class, and Dot1P parameters can be specified to be used by every protocol packet generated by the node. This enables prioritization or de-prioritization of every protocol (as required). The markings effect a change in behavior on ingress when queuing. For example, if OSPF is not enabled, then traffic can be de-prioritized to best effort (be) DSCP.

For information about the tasks and commands necessary to access the command line interface and to configure and maintain your 7210 SAS E, refer to CLI Usage chapter in the 7210 SAS E OS Basic System Configuration Guide.
Page 199: Basic Configurations
Slope QoS Policies Basic Configurations A basic slope QoS policy must conform to the following: • Each slope policy must have a unique policy ID. • High slope and low slope are shut down (default). • Default values can be modified but parameters cannot be deleted. Create a Slope QoS Policy Configuring and applying slope policies is optional.
Page 200 Overview Use the following CLI syntax to configure a slope policy: CLI Syntax: config>qos slope-policy name description description-string high slope start-threshold percent queue queue-id drop-rate rate no shutdown low-slope start-threshold percent queue queue-id drop-rate rate no shutdown The following displays the slope policy configuration: A:ALA-7>config>qo>slope-policy# info ---------------------------------------------- description "slope policy SlopePolicy1"...
Page 201: Applying Slope Policies
Slope QoS Policies Applying Slope Policies • Ports Apply slope policies to the egress buffer pool on the physical ports. Ports The following CLI syntax examples may be used to apply slope policies to ports: CLI Syntax: config>port>access>egress>pool>slope-policy name config>port>accesss>uplink>egress>pool>slope-policy name 7210 SAS-E OS Quality of Service Guide Page 201...
Page 202: Default Slope Policy Values
Overview Default Slope Policy Values The default access egress and access uplink egress policies are identified as policy-id “default”. The default policies cannot be edited or deleted. Table 27 displays default policy parameters: Table 27: Slope Policy Defaults Field Default description Default slope policy high (RED) slope...
Page 203: Deleting Qos Policies
Slope QoS Policies Deleting QoS Policies A slope policy is associated by default with access and access uplink egress pools. A default policy may be replaced with a non-default policy, but a policy cannot be entirely removed from the configuration. When a non-default policy is removed, the policy association reverts to the default slope policy policy-id default.
Page 204: Copying And Overwriting Qos Policies
Overview Copying and Overwriting QoS Policies You can copy an existing slope policy, rename it with a new policy ID value, or overwrite an existing policy ID. The option must be specified or an error occurs if the destination overwrite policy ID exists.

Page 209 QoS Commands Configuration Commands Generic Commands description Syntax description description-string no description Context config>qos>slope-policy 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 210 Slope QoS Commands Operational Commands copy Syntax copy slope-policy src-name dst-name [overwrite] Context config>qos Description This command copies existing QoS policy entries for a QoS policy-id to another QoS policy-id. The copy command is a configuration level maintenance tool used to create new policies using exist- ing policies.
Page 211 QoS Commands Slope Policy QoS Commands slope-policy Syntax [no] slope-policy name Context config>qos Description This command enables the context to configure a QoS slope policy. Default slope-policy “default” Parameters name — The name of the slope policy. Values Valid names consist of any string up to 32 characters long composed of printable, 7- bit ASCII characters.
Page 212 Slope QoS Commands Slope Policy QoS Policy Commands high-slope Syntax [no] high-slope Context config>qos>slope-policy Description The high-slope context contains the commands and parameters for defining the high priority Random Early Detection (RED) slope graph. Each buffer pool supports a high priority RED slope for manag- ing access to the shared portion of the buffer pool for high priority or in-profile packets.
Page 213 QoS Commands RED Slope Commands shutdown Syntax [no] shutdown Context config>qos>slope-policy>high-slope config>qos>slope-policy>low-slope Description This command enables or disables the administrative status of the Random Early Detection slope. By default, all slopes are shutdown and have to be explicitly enabled (no shutdown). The no form of this command administratively enables the RED slope.
Page 214 Slope QoS Commands queue Syntax queue queue-id drop-rate num no queue queue-id Context config>qos>slope-policy>high-slope config>qos>slope-policy>low-slope Description Sets the low priority or high priority Random Early Detection (RED) slope drop-rate for the shared buffer per queue. The drop-rate num parameter is expressed as a scalar number, and mapping to the percent of packets dropped in congestion conditions is specified in Table 16, Drop Rate Value to Per- cent Mapping Values, on page...
