QoS on Meraki for Microsoft Teams

0

Howdy folks,

I’ve been a long time user of Meraki equipment and I am thoroughly thrilled to bits on how well it performs and how easy it is to configure.  One thing I have noticed while doing testing on my Microsoft Teams deployments with direct routing is that  I couldn’t see the Quality of Service, QoS, tagging being honoured by the network.  Here is how I’ve done it and I hope it helps you too.  In this post, I’ll show you how to configure a Security Appliance, Switches, and Wireless Access Points.

Before we get started on the Meraki side of things, make sure you enable QoS in Microsoft Teams.  Mark Vale has written a complete guide of enabling this within the Admin Center:  https://blog.valeconsulting.co.uk/2018/07/24/microsoft-teams-quality-of-service/  

By default, QoS is turned off on Meraki equipment.  Let’s work our way through the Meraki Dashboard and we’ll show you how to enable the Traffic Shaping and QoS functionality.

 

Security Appliances:

Select Security Appliance, Traffic Shaping, and then go to Traffic shaping rules.

Select the Enable default traffic shaping rules and click save.

 

Switches:

Go to Switch, Switch Settings, and Quality of Service

You will initially be greeted with the QoS service being turned off.

Click the Add a QoS rule for this network

 

We want to honour the QoS tagging on both TCP and UDP, this is a protocol of Any.

 

In addition, we want to Trust incoming DSCP configuration

 

We can view what the trusted DSCP to COS Mapping like however, this matches the Microsoft Recommendation.

Microsoft Teams QoS configuration can be found here:

https://docs.microsoft.com/en-us/microsoftteams/qos-in-teams

Finally, don’t forget to save

 

Wireless AP:

To enable QoS on Meraki Wireless Access Points, you will need to go to Wireless, Firewall & traffic shaping and enable

By default nothing is selected, you will need to enable traffic shaping by dropping down the Share Traffic on this SSID

 

Select the default Rules and drop down the Enable the default traffic shaping rules, from the drop-down.

 

You’ll see the required items for Teams is there, DSCP tags 46, 34, and 18.

 

Click Save.

 

Do this for all SSID that require to have the Traffic Shaping and QoS Rules applied.

 

Conclusion

That’s it, once this has replicated back to your equipment this should then have the correct QoS and Traffic Shaping information on your Meraki Network.
