Hey all I have a MX68 in an environment with a bunch of devices - average 130 clients a day. Half of these devices are LAN only ie NAS's, switches, IoT sensors, point to point bridge units. For those who know me, it's a retreat center. Recently, we've had a few larger groups come and the device has seemingly hard crashed. It has happened once every 2-3 weeks and requires a hard reset. Meraki support says the device is spec'd for 50 clients (insane for the money and I dont mind saying it out loud) and that it has been spiking high in utilization/CPU usage, like pegged high. I have nothing fancy going on.. a service VLAN and regular client VLAN, but not passing any data between them. Everybody on my network is texting, YouTubing, browsing the web and using web apps etc. Consumer usage. Ok so it is what it is. Support's suggestion was that if I didn't need one or both of the Advanced Security Package options to disable them, as the deeper packet inspection would raise utilization. We are an Apple/iOS/macOS house almost exclusively and when guests come honestly if they have PCs and don't have their own virus protection that's on them, so I decided to disable AMP. Looking at the event log in Security Center I have no confirmed positives, all clean. Looking at the utilization graph things do seem to have calmed down significantly but I havent yet been able to test it with a high influx of guests. If this continues, this will force me off of Meraki MX solutions and into something like Fortigate or Firewalla. Any other thoughts or suggestions from this incredible support community welcome. Here's the graph for the last few days. I turned AMP off on the 2nd of August. This is with standard client load of 130, with half of those being actual devices as I stated above.
