Setting Up Ethernet Services

You can create and manage Ethernet services through the Traffic menus. The major steps required to create or manage services are:

1. 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".

2. 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".

3. 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 LX-S (formerly Accedian Skylight performance element: LX/LX-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 (See "Setting Up Ethernet Services").

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

1. Access the page Traffic ▶Configuration.

2. Select which VLAN you want to filter on for each policy list, then click Apply.

For more information on specific parameters, "Traffic Configuration (System ▶Configuration ▶Traffic ▶Rate)".

Viewing VID Sets

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").

To set up a bandwidth regulator

1. Access the page Traffic ▶Regulators ▶Configuration.
   A summary of all existing bandwidth regulators is displayed.
   

   ---

   Note: No bandwidth regulators are defined by default.

   ---

2. Click Add to add a new bandwidth regulator or click the Name of an existing bandwidth regulator to edit its settings.
   The New Regulator Configuration page is displayed.

3. Complete the required fields, then click Add.

For more information on specific parameters, refer to the following table.

Regulator Configuration (Traffic ▶Regulators ▶Configuration)

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.
• DSCP: DSCP bits in the IPv4 ToS 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. ("Setting Up Ethernet Services").

Before configuring a bandwidth regulator set, you must first set up a number of traffic regulators ("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

1. 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.

2. 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.

3. Complete the required fields, then click Apply.

For more information on specific parameters, refer to the following table.

BWR Set Configuration (Traffic ▶Mapping ▶Bandwidth Regulator Sets)

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.
• DSCP: DSCP bits in the IPv4 ToS 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

1. Access the page Traffic ▶Mapping ▶CoS Profiles.
   A list of existing CoS profiles is displayed. Four commonly-used profiles have been preconfigured.

2. Click the Add button to add a new CoS profile or click the Name of an existing CoS profile to edit its settings.

3. Complete the required fields, then click Apply.

For more information on specific parameters, refer to the following table.

CoS Profile Configuration (Traffic ▶Mapping ▶CoS Profiles)

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.

To configure port CoS mapping values

1. Access the page Traffic ▶Mapping ▶Port CoS Mappings.
   The Port CoS Mapping Configuration page opens. All the unit’s physical ports and logical (LAG) ports are listed in a grid.

2. Click a port or LAG from the list to select it and configure its port CoS mapping.

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.

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.
