Hello All
I'm in the process of replacing a customer's existing network (Cisco Catalyst 2960x switches), which has QoS enabled.
We are migrating to Catalyst 9300M switches. I'll discuss with the customer about their QoS requirements (if indeed required at all) as I suspect the configuration was in place when WAN links were much lower in terms of bandwidth.
I've read some great articles on this forum relating to QoS on the MS platform (see below links).
https://community.meraki.com/t5/Security-SD-WAN/Meraki-MS-QoS-behavior-question/m-p/203036
https://community.meraki.com/t5/Switching/Recommended-QOS-settings/m-p/206113
From what I gather the Meraki MS provides a much more simplified QoS offering. I just want to ensure I am correct , in my assumption as the Meraki Documentation is rather limited.
1. To enable QoS I have to specifically configure vlan(s) via the below setting.
- Switch > Configure > Switch settings. Find the section Quality of service.
- Click Add a QoS rule for this network
This allows me to trust the DSCP values on the specific traffic, and/or set the DSCP value if required.
By performing the above step I am automatically saying "I want to apply QoS to this traffic"
I get the DSCP to CoS mapping and also the associated CoS to Weight x 6, configurable queues.
What I can't seem to find is anything to say under what conditions QoS is applied to a link/interface. In "traditional" Cisco platforms QoS only kicked in (excluding policing, shaping) when the interface was congested, assume Meraki operates in a similar manner? Is below the only Meraki documentation on QoS for the MS switches.
