High traffic mDNS

Screenshot_2021-02-17 Clients - Meraki Dashboard.pngHi Guys, I found this type of traffic on Meraki MX68, one printer in the network generates too much traffic mDNS .

What's going on ?

Re: High traffic mDNS

Whoa, that’s a fair amount of mDNS traffic! If that’s all coming from one device I’d be thinking there might be something wrong with it (maybe it needs a firmware update). My suspicions would be Apple Print technologies if they’re built into it, they use Bonjour, which uses mDNS - maybe turn them off and see if it ‘goes away’.
