Meraki DNS Settings

Hello,

I am looking for some insight into configuring DNS on Meraki Switching VS Meraki MX. If I am configuring DNS on the Meraki MX on the network edge under uplink settings, then configuring DNS on each individual switch in my network as well, if I don't use the same settings.. which would a client attached to one of those switches use, the MX or the MS?

I tend to see "DNS is misconfigured" even while the configuration is verified, and correct. Often, it's due to some sort of caching going on, so I'd wait a couple of hours and see if it goes away on it's own.

Re: Meraki DNS Settings

DNS settings affect the Meraki box you're configuring, e.g. for being able to talk to the dashboard. That does not affect your client devices at all, these would receive their DNS settings via DHCP (possibly).

Re: Meraki DNS Settings

Those are static overrides like on a client computer. Depending there the client is getting DHCP from then that will determine the DNS server used, otherwise fall back to static assignment

@SoCalRacer  Thank you for your reply. My Switch is  assigned 1.1.1.1 and 8.8.8.8 yet experiences "DNS is misconfigured" and becomes disabled intermittently. This causes their clients to fail until the alert clears.

@CptnCrnch Hi Thank you for your response. My only point of confusion lies in the behavior this causes, when the switch is alerting DNS is misconfigured, the clients are affected and cannot resolve DNS.

Re: Meraki DNS Settings

I assume a reboot on the switch has been done and firmware is up to date?

@SoCalRacer 
Yep. We did a reboot this morning on the switch experiencing the issue, but not the entire stack. SW2 and SW3 didnt seem to be affected, or at least did not show the same alert. 

Code is up to date

Current version: MS 12.17
