Packet Prioritization

[carl222]

Hi,

We have a branch with limited Internet bandwidth. I need to prioritize Teams, Office 365 and microsoft.com traffic.

I am a bit confused by this documentation:

https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/Using_Packet_Prioritization_on_a_Tr...

Do I need to just basically put a single custom traffic shaping rule for these apps and set priority to High ?

High priority will give me 4/7 of the bandwidth but what about the rest of the traffic, will it be treated as Normal 2/7 ?

Thanks

Yes 1 rule is fine

Yes all other traffic is treated as Normal

The first thing you need to do is configure the uplink WAN upstream and downstream speed parameters.  You'll need to measure these, and then configure the settings to match.

https://documentation.meraki.com/MX/Firewall_and_Traffic_Shaping/SD-WAN_and_Traffic_Shaping#Uplink_b... 

Then under Security & SD Wan/Traffic Shaping and QoS I would only enable the default rules.

Then I would go into the Microsoft Teams admin portal, and enable QoS.

@PhilipDAth I don't have QoS enabled on the downstream L2 switch. Does that make a difference ?

What are these Default Rules doing anyways ?

Do they mark packets or they respect marking and queue/schedule packets accordingly ?

Thanks

>respect marking and queue/schedule packets accordingly

Correct.  If you have applications that need QoS they can usually mark their own packets.

I can't remember when I last had to configure QoS on a Meraki MX - the default rules work great.  Meraki simple.

@PhilipDAth All right so problem solved for Teams.

Now what about Netflix and YouTube. We cannot completely block them for business reasons but we also don't want them to hug all their bandwidth.

How would you proceed ?

Custom rules and put them in low priority ? This is what I have in mind :

I wouldn't normally both with priority.  I would just set a bandwidth limit.
