Hi Victor,   Why would Meraki leave this version available with a bug like this present? I wouldn't count this as acceptable even on a product where upgrades were 100% manual, having this on a product that automatically upgrades is reckless at best.   These are production appliances that Cisco is heavily pushing and I'd expect better from a product line with a lease/subscription-style cost model. ...

I don't think my issue was spanning-tree related (I mentioned it because the logs v/ the website only show stp events on port down/up). The symptoms were identical though- the switch wasn't forwarding any local traffic. I know the interfaces reset as the clients on the network attempted to renew DHCP leases and failed. Bouncing the MS220 brought the network back up temporarily as mentioned.   I had the issue occur in a home-office environment with a flat network with the MS220 being the only switch installed - single VLAN, no loops, all ports configured as access ports including one to an AIR-CAP3702i in Autonomous mode. ...

I've had to rollback to MS 9.27 from MS 9.32 on an MS220-8P today - after the firmware update the device experiences 2-5 minutes of normal operation and then locks up, resetting interfaces and getting stuck with an orange indicator LED. Rollback immediately restores operations.   The logs for the MS only show stp events so it's difficult to diagnose. I'll try to upgrade again tonight and see if it was a glitch in the upgrade process, or if it's something that is reproducible. ... View more
