Traffic type in SDA

[rasmus.elmholt]

Hi,

Multiple places in the SDA configuration it is possible to define traffic types to be Data and/or Voice.

Choose the Traffic type from the drop-down list.

You can choose to send voice or data traffic through the virtual network.

You have the option to select this multible places like Host Onboarding -> Virtual network -> IP pool and Host Onboarding -> Wireless SSID.

Can anybody tell me what this setting does exactly to the configuration of the Pool/Client and to the traffic in the fabric?

References to official documentation would be great as I am not able to find any information on this.

There is no practical difference on actual switches (as its just a vlan, an SVI, an L2 LISP instance and a DT pool just like any other vlan). But it will be considered as possible pool to be elected under the following drop down menu:

* Host onboarding Voice VLAN pool
* ISE Authorization Profile when selecting "SGT" as AV Pair, as DNAC pushes the Pool as part of an existing VN on ISE.

Yes, and we always configure it on the pool, the WLAN, and on the authorization profile as well. But why? When there is no difference?

Does it have anything to do with QoS config?

Anyone figure this one out or is it a mystery!

Hi @KatherineTran 

As far as I'm aware, the Traffic Type (or Type of Enterprise/Guest Network) setting under Design -> Network Settings -> Wireless, dictates the QoS policy that will be applied to the associated SSID during provisioning. 'Voice and Data' will enable a QoS SSID policy of Platinum and 'Data' will enable a QoS SSID policy of Silver. Note in the later versions of DNA Center you can now select VoiP (Platinum), Video (Gold), Best-Effort (Silver) and Non-Real Time (Bronze) under Traffic Type which is much clearer and more flexible

The Traffic setting when adding an IP address pool to an SDA virtual network only impacts the options that are presented when configuring a fabric edge port using the DNAC Host Onboarding application. If the IP address pool is set to 'Data' the IP pool can only be configured as the switchport Data VLAN (switchport access vlan <vlan>). If the IP address pool is set to 'Voice' the IP pool can only be configured as the switchport Voice VLAN (switchport voice vlan <vlan>). 

I'm not aware of any other differences when the traffic type is set as Voice or Data.

Hope that this helps.
