Creating 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. Traffic type profiles enable you to assign priority and service level criteria for traffic types. You can link an application traffic type profile with an application SLA profile, which can be linked to an SD-WAN policy intent.
To create an Application Traffic Type profile:
- Select Configuration > SD-WAN > Application Traffic Type Profiles.
The Application Traffic Type Profiles page appears.
- Click the Add (+) icon to create a new traffic type profile.
The Create New Traffic Type Profile page appears.
- Configure the traffic type profile parameters as per the guidelines provide in Table 1.
- Click OK to save the traffic type profile configuration.
If you want to discard your changes, click Cancel instead.
If you click OK, 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
Enter the name of the traffic type profile that you want to create. Can be a unique string of not more than 15 characters that contains alphanumeric characters and hyphen (-).
Select the priority value that you want to assign to the traffic type profile. Traffic type profiles with higher priority values takes precedence over the ones with lower values when network congestions occur.
Note: You cannot create two traffic type profiles with S-High or High priority.
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.
S-High, which denotes strict high or the highest priority.
M-High, which denotes medium high.
M-Low, which denotes medium low.
Click the toggle button to enable the traffic type profile. You can only have a maximum of six traffic profiles enabled at a time. You can assign only those traffic type profiles that are marked as enabled to application SLA profiles.
Note: If there are more than six traffic type profiles enabled when you deploy a policy, the policy deployment fails.
Tip: You can select one of the already configured traffic type profiles from the Copy probe parameters from list to populate the values in the probe parameters fields. When you select a traffic type profile, the probe parameter values associated with that profile are populated to the fields. You can edit the values if required. .
Specify the size of the data packets, in bytes, to be used for active probes. The range is 4 through 256.
Specify the interval, in seconds, between two probes. The range is 1 through 10.
Specify the number of probes that form a test. The range from 10 through 1000.
Specify the maximum number of probes that can be sent in one go. The range is from 10 through 100. The value for this parameter must not exceed the value you configured for Probe Count.
Choose the DSCP value that you want to assign to the traffic type profile. Differentiated Services Code Point (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: You can assign a DSCP value to only one traffic type profile.
(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.
(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 the traffic type never exceeds the maximum bandwidth configured for the traffic type.
Move the slider button to choose the bandwidth buffer that you want to allocate to the traffic type profile.
Note: The total buffer allocation of all the traffic type profiles that are in enabled state must not exceed 100%.
