Add Traffic Type Profiles

 

You can use traffic type profiles to configure class-of-service parameters for various types of traffic. Traffic type profiles enable you to configure class-of-service parameters based on your specific business requirements, and assign priority and service level criteria for traffic types. You can link an application traffic type profile with a steering profile, which can be linked to an SD-WAN policy intent.

Note

The Add Traffic Type Profiles operation can be performed by users with an SP Administrator role or an OpCo administrator role.

To add an application traffic type profile:

  1. Select Configuration > SD-WAN > Application Traffic Type Profiles.

    The Application Traffic Type Profiles page appears.

  2. Click the Add (+) icon.

    The Create New Traffic Type Profile page appears.

  3. Configure the traffic type profile parameters as per the guidelines provide in Table 1.Note

    Fields marked with an asterisk (*) are mandatory.

  4. Click OK.

    A confirmation message appears indicating the job is created for adding a traffic type profile. You can view the status of the job from the Jobs page (Monitor > Jobs).

    After the job is complete, the traffic type profiles that you configured appear on the Application Traffic Type Profiles page.

    Table 1: Fields on the Create Traffic Type Profiles page

    Field

    Description

    General

    Name

    Enter a unique name that can contain alphanumeric characters and hyphens (-); the maximum length is 15 characters.

    Priority

    Select the priority value that you want to assign to the traffic type profile.

    The following list is arranged in the decreasing order of priority, where the first item indicates the highest priority and the fifth item, the lowest priority.

    1. S-High, which denotes strict high or the highest priority.

    2. M-High, which denotes medium high.

    3. High

    4. M-Low, which denotes medium low.

    5. Low

    When network congestion occurs, traffic type profiles with higher priority take precedence over the ones with lower priority.

    Note: You can enable only one profile with S-High and one profile with High priority at any given time

    Status

    Click the toggle button to enable the traffic type profile. By, default, the traffic type profile is disabled. You can enable a maximum of six traffic profiles at a time. You can assign only those traffic type profiles that are marked as enabled to application SLA profiles.

    Quality of Service

    Probe Parameters

    The following are the parameters for probes that are sent on links other than the active links:

    • Data Size

    • Probe Interval

    • Probe Count

    • Burst Size

    Probe results are used to verify the SLA compliance of links and to identify the best available link to which traffic can be routed if the active link fails to meet SLA.

    Copy probe parameters from

    You can select an existing traffic type profile from the Copy probe parameters from list to copy the probe parameters from that profile, and, if required, modify the values.

    Data Size

    Specify the size of the data packets, in bytes, to be used for active probes.

    Range: 4 through 256.

    Probe Interval

    Specify the interval, in seconds, between two probes.

    Range: 1 through 10.

    Probe Count

    Specify the number of probes within a test packet.

    Range: 10 through 1000.

    Burst Size

    Specify the maximum number of probes that can be sent in one go. The burst size must be less than or equal to the probe count.

    Range: 10 through 100.

    Bandwidth

    DSCP Value

    Choose the Differentiated Services Code Point (DSCP) value that you want to assign to the traffic type profile. DSCP values define the forwarding properties of the packet within the Differentiated Services framework. You can assign an Expedited Forwarding (ef), an Assured Forwarding (af), the Best Effort (be), or a Class Selector (CS) value. Class Selector value provides backward compatibility with IP Precedence. You can choose one of the following DSCP values:

    Note: For a traffic profile you assign only one type of DSCP value. .

    • ef

    • af11

    • af21

    • af22

    • af23

    • af31

    • af32

    • af33

    • af41

    • af42

    • af43

    • be

    • cs1

    • cs2

    • cs3

    • cs4

    • cs5

    • nc2/cs7

    IEEE 802.1P Value

    Select an IEEE 802.1p value to assign to the traffic type profile. IEEE 802.1p value specifies the QoS at the media access control (MAC) level. You can assign an Expedited Forwarding (ef), an Assured Forwarding (af), the Best Effort (be), or a Class Selector (CS) for the IEEE 802.1p Value.

    You can choose one of the following values:

    • None

    • be (000)

    • be1 (001)

    • ef (010)

    • ef1 (011)

    • af11 (100)

    • af12 (101)

    • nc1 (110)

    • nc2 (111)

    • cs6 (110)

    • cs7 (111)

    Drop Priority

    Drop priority, in case of congestion.

    The values for drop priority in order of high-to-low is:

    • Strict High

    • High

    • Medium-High

    • Medium-Low

    • Low

    Minimum Bandwidth

    (Optional) Move the slider button to choose the minimum bandwidth, as percentage of the total available bandwidth, that you want to allocate to the traffic type profile. The minimum bandwidth value denotes the guaranteed bandwidth allocation for the traffic type.

    Maximum Bandwidth

    (Optional) Move the slider button to choose the maximum bandwidth, as percentage of the total available bandwidth, that you want to allocate to the traffic type profile. The bandwidth allocation for a traffic type never exceeds the maximum bandwidth configured for the traffic type.

    Buffer

    Allocation

    Move the slider button to choose the bandwidth buffer that you want to allocate to the traffic type profile.

    Buffer allocation enables interfaces to queue and transmit traffic when there are large bursts of traffic and thus reduces the packet loss when network congestions occur. You can specify the buffer allocation as a percentage of the total available delay buffer.

    Note: The total buffer allocation of all the traffic type profiles that are in enabled state cannot exceed 100%.
