You can create and manage Ethernet services through the Traffic menus. The major steps required to create or manage services are:
- Define Filters (Classify Traffic): The system is designed in a way that the traffic must first be classified before sending it to any service creation function (Service mapping, bandwidth profile or filters). Three different types of filters can be defined:
- Layer-2 filters and IPv4 filters. "Defining Filters".
- VID Sets. "Setting Up VID Sets".
- Define Service Attributes:
- Define bandwidth profiles. "Setting Up Bandwidth Regulators".
- Define CoS mapping: Sets VLAN priority based on DSCP, IP Precedence or PCP values of the ingress frame. "Setting Up CoS Profiles".
- Define bandwidth regulator sets. "Setting Up Bandwidth Regulator Sets".
- Create the Service ("Setting Up Traffic Policies"):
- Select the filter that you defined in the first step.
- Select the action to be applied to the traffic flow defined by the filter (Drop or Permit Traffic).
- Assign or select one or more of the following characteristics:
- EVC Mapping (encapsulation, Ethertype, VLAN ID)
- CoS Mapping (PCP action, Type, CoS profile or default mapping)
- Bandwidth profile (Regulator set if CoS Mapping is Preserve or Map, single Regulator (bandwidth profile) for default mapping or direct CoS mapping
To view a summary of the policy configurations, access the page Traffic ▶Policies.
Setting Up VID Sets
A VID set comprises one or more VLANs grouped in a logical entity. You can define VID sets for each traffic stream. For the Cisco Provider Connectivity Assurance Sensor LT-S (formerly Accedian Skylight performance element: LT/LT-S) Traffic-5, Traffic-6, Traffic-7 and Traffic-8 classify the incoming traffic before sending it to the service creation function.
Once a VID set is created, you can apply it to traffic policies as a filter.
VLAN Filtering
You can create VLAN filters using the VLAN type field (S-VLAN or C-VLAN) and VLAN ID or Range.
When using VLAN filtering, you also need to select the VLAN (inner or outer VLAN) for filtering the traffic for each policy list, e.g. Traffic-8.
To enable VLAN filtering
Access the page Traffic ▶Configuration.
Select which VLAN you want to filter on for each policy list, then click Apply.

Setting Up Bandwidth Regulators
You can set up bandwidth profiles (and the corresponding bandwidth regulators to enforce them) through the Traffic ▶Regulators ▶Configuration page. Compared to shaping, traffic regulation can easily scale to a high number of services per port.
The regulators you define are used to share token between services. The number of traffic regulators that can be defined varies, depending on the model you are using. Once a bandwidth regulator has been created, you can apply it to traffic policies ("Setting Up Ethernet Services").
Note: Disabling then re-enabling a regulator resets the CBS and EBS token buckets.
To set up a bandwidth regulator

Setting Up Bandwidth Regulator Sets
A bandwidth regulator set is used to regulate traffic bandwidth based on the value of the following information of the incoming frames:
- PCP: p-bits in 802.1Q / 802.1Q-in-Q tags.
- IP Precedence: IP precedence bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.
- DSCP: DSCP bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.
Once a bandwidth regulator set has been created, you can assign it to traffic policies for rate enforcement based on the map type being used.
Before configuring a bandwidth regulator set, you must first set up a number of traffic regulators (See "Setting Up Bandwidth Regulators").
To configure the bandwidth regulator set, you must assign in the mapping table, a traffic regulator (to a specific PCP, IP precedence or DSCP value. This table has N rows, where N depends on the type of the regulator set. If the type is PCP or IP precedence, then N=8. If the type is DSCP, N=64.
To configure a bandwidth regulator set
Access the page Traffic ▶Mapping ▶Bandwidth Regulator Sets.
A listing of the existing bandwidth regulator sets is displayed. For more information on specific parameters, refer to the table at the end of this procedure.Click the Add button to add a new bandwidth regulator sets or click the name of an existing bandwidth regulator set to edit its settings.

Setting Up CoS Profiles
A CoS profile is used to map an input frame to a Layer-2 class of service based on the conformance level (Green/Yellow) of the incoming traffic and on the value of the following information of the incoming frames:
- PCP: p-bits in 802.1Q / 802.1Q-in-Q tags.
- IP Precedence: IP precedence bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.
- DSCP: DSCP bits in the IPv4 ToS byte or in the IPv6 Traffic Class byte.
Once a CoS profile is created, you can apply it to traffic policies for CoS mapping and bandwidth policing. "Setting Up Ethernet Services".
To set up the CoS profile, you need to assign in the mapping table, a class of service value (0–7) to the outgoing traffic based on the conformance level (Green/Yellow) of the incoming traffic and on the mapping entry. The mapping table has N rows, where N depends on the type of the CoS profile. If the CoS profile type is PCP or IP precedence then N=8. If the CoS profile is a DSCP, N=64.
To set up a CoS profile

Setting Up Port CoS-to-PCP Mapping
A port CoS mapping is used to control the class of service assigned to the outer VLAN tag of input frames on which a dual VLAN tag action (e.g. push-push or push-replace) was applied in the unit. There is one configurable port CoS mapping for each physical or logical (LAG) port in the system.
The Port CoS mapping defines how to map the PCP (Priority Code Point) value of the outer VLAN tag based on the conformance level (Green/Yellow) of the outgoing frame and on the PCP value of its inner VLAN tag.
The mapping configuration is a translation table from one Service Provider's priority scheme to another's. Consequently, if you are not putting traffic through multiple Service Providers' networks, you do not need to modify the values in this page.

Understanding BLUE
The BLUE algorithm is used by the shapers for queue management.
BLUE is an enhancement to the RED congestion avoidance algorithm; it offers the same benefits as RED and provides similar queue monitoring. The main difference between BLUE and RED is that BLUE also uses the queue packet loss and utilization history. Its use of a drop probability is more friendly with TCP global synchronization and reduces the number of TCP retransmissions.
Each shaper uses BLUE to manage queues based on link use. It maintains a marking probability (pm) that is used to either mark or drop the frames. If the queue is continually dropping the frames, pm is increased by the factor d1. If the queue is empty or link is idle, pm is decreased by the factor d2.
Note: The value of d1 should be set significantly larger than that of d2. This is because link is underused when congestion management is either too aggressive or too conservative, but frame loss occurs only when congestion management is too conservative.
BLUE uses also freeze_time, which determines the time interval between two successive updates of pm. It allows the changes in the marking probability to take effect before the value is updated again. The BLUE algorithm is expressed as follows:
Upon Qlen > L1) event:
if ( ( now - last_update) > freeze_time )
pm := pm + d1
last_update := now
Upon Qlen < L2event:
if ( ( now - last_update) > freeze_time)
pm := pm - d2
last_update := now
To disable the BLUE algorithm
You might need to disable BLUE if your test equipment does not support it.

Configuring Queues
The Assurance Sensor LT-S has dedicated queues per port as listed below:
Parameter | Description |
---|---|
1 Gbps Ports | Four dedicated queues per 1 Gbps port:
|
10 Gbps Ports | Sixteen dedicated queues per 10 Gbps port:
Eight dedicated queues per 10 Gbps port:
|
10 Gbps Ports (NNIto-NNI Traffic) | Sixteen dedicated queues per port used for NNI-to-NNI traffic in an Ethernet Ring Protection (ERP) topology:
|
Each queue has a defined port and size. There are no user-assignable queues. When in LAG mode, the queues dedicated to the LAG’s ports are unavailable because the LAG’s own queues are used instead.
Note: Definitions: RPTQ stands for Ring Pass Through Queue. ADQ stands for Adequate Queuing Profile. DQP stands for Default Queuing Profile. You do not have to configure a queue for H-QoS if you do not plan to use the queue.
To configure queues
Access the page Traffic ▶Shaping ▶Queue ▶Configuration.
The Traffic Shaping Queue Configuration page opens. All the unit’s queues are listed in a grid.Select a queue from the list to configure by clicking it.
The queue’s details are displayed.Use the information in the table below to configure the queue, then click Apply.
For more information on specific parameters, refer to the following table.
Queue Settings (Traffic ▶Shaping ▶Queue ▶Configuration)
Parameter | Description |
---|---|
Outgoing Port | Traffic from this queue will egress on the port specified here. |
Name | The name assigned to this shaper. |
Queue Scheduling
Parameter | Description |
---|---|
Priority (0–7) | The strict scheduling priority assigned to this queue: 7 is the highest and 0 the lowest priority. Note: This value is provided for your convenience; however, it cannot be modified. When several queues have the same priority, scheduling is carried out in a round-robin fashion. |
Color | Make a selection from the drop-down list to assign a queue scheduling color to this queue. Queues without an enabled shaper can have a CIR or EIR priority. When the queue scheduling color is set to green, the queue priority is configured for CIR scheduling; when the queue scheduling color is set to yellow, the queue priority is configured for EIR scheduling. |
Queue Management Parameters
Parameter | Description |
---|---|
Maximum Queue Size (KiB) | The buffer's size, expressed in KiB (1024 bytes). Acceptable values range from 16 KiB–8000 KiB. Note: To be able to set the queue size to 8000 KiB on a specific port, the queue size needs to be decreased on other queue ports to ensure enough memory is available. The Maximum Queue Size must be greater than the Yellow Threshold value. |
Yellow Threshold (KiB) | When the queue length reaches this threshold, tail-dropping is performed on new packets with yellow marking. Acceptable values range from 16 KiB to the Maximum Queue Size value indicated above. |
BLUE State | Select to enable the BLUE queue management algorithm. The buffer is used to queue frames for later transmission. If the BLUE state is enabled, congestion management is ruled primarily by the BLUE queue management algorithm. If not, it is managed through simple tail-drops. |
BLUE Queue Full Threshold (%) | Once the queue fills to the specified percentage, the marking probability will be increased. The current range is from 5–98. The Blue Queue Full Threshold must be equal or greater than the Blue Queue Empty Threshold. |
BLUE Queue Empty Threshold (%) | Once the queue empties to the specified percentage, the marking probability will be decreased. The current range is from 5–98. The Blue Queue Empty Threshold must be less than the Blue Queue Full Threshold. |
BLUE Marking Probability Freeze Time (μs) | This value determines the minimum interval time, expressed in microseconds (in increments of 10) between two successive updates of marking probability. Maximum of 655350 μs |
BLUE Marking Probability Increment (%) | The marking probability is incremented by this value (expressed as a step percentage) in the event of a buffer overflow. Notes: If this parameter is set to 0, the BLUE algorithm is disabled. Maximum of approximately 25%. |
BLUE Marking Probability Decrement (%) | The marking probability is decremented by this value (expressed as a step percentage)if the link is idle. Notes: The percentage value you enter here is only an approximation; the actual configured value appears to the right of this field. The percentage value you enter here is only an approximation; the actual configured value appears to the right of this field. Maximum of approximately 25%. |
Note: When modifying the Bandwidth Regulators' CIR/CBS and EIR/EBS configuration, the user must ensure that the Queue Management Parameters, Maximum Queue Size, and Yellow Threshold are properly configured to match the desired SLA.
