MX Low Latency Queue

New here

MX Low Latency Queue

We are migrating some locations over from Cisco ISR routers to Meraki MX.

The QoS design needs support for a low latency queue and being able to have the VoIP DSCP copied to the outside of the VPN packets after they leave the MX towards the remote site.

 

Is this something that can be done today or is road mapped?

 

Thanks in advance Jordan

Kind of a big deal

Re: MX Low Latency Queue

This can be done today.

 

Here is some info about QoS over VPN:

https://documentation.meraki.com/MX-Z/Firewall_and_Traffic_Shaping/QoS_over_a_Site-to-site_VPN

 

For priority queuing look at this:

and jump down to "Rule Actions".

Re: MX Low Latency Queue

Hello,

 

Appreciate your response. I had a look at both of the URLs above.

This isn't what I am looking for.

 

URL 1 - QoS with VPN Tunnel

This talks about QoS DSCP on the LAN side of the VPN tunnel and re-adding as it it is decapsulated on the far LAN side.

What we need is QoS on the outside of the Encapsulated VPN packets so that internet and upstream equipment honors the QoS we specify on the traffic type before it is encrypted. This is a standard Cisco IOS Router feature.

 

URL 2 - Priority Queuing

This was a good read about traffic shaping. What we are actually looking for is a Class Based Low Latency Queue that matches DSCP values so that in all cases it is prioritized. This will benefit us so that no matter how the WAN speeds are configured or traffic shaping is configured there will be guaranteed priority.

 

Hopefully there is some more info out there on the options coming down the pipe. Thanks!

Kind of a big deal

Re: MX Low Latency Queue

You are trying to apply a strick IOS concept to Meraki.  I'm telling you the equivalent method in Meraki.

 

Meraki has three queues, low, medium and high.  You use traffic shapping rules to put traffic into one of these three queues.  The queues are served in the ratio in the document link I supplied.  You can not configure the queues in any way.

 

This is your only option.
