I have 3 MS350 stacks, 6 switches in each stack, running on 8.10 software.
All stacks have been up and running without issue for the past month or so. No changes have been made on the Meraki switches or the Cisco Nexus 9k's that are upstream.
This morning within an hour all 3 stacks had switches that removed themselves from the stack and stopped forwarding traffic.
Stack 1 - 1 switch disappeared from the stack and stopped forwarding traffic - Did not come online until after a reboot. Uplink port was not on this switch.
Stack 2 - 1 switch disappeared from the stack and stopped forwarding traffic - Did not come online until after a reboot. Uplink port was not on this switch.
Stack 3 - 5 of the switches disappeared from the stack - 1 of the uplinks was on one of the switches that disappeared from the stack. After rebooting the switch with the uplink the 5 switches rejoined the stack. 1 switch in this stack stayed online, that switch has an uplink to the core.
It seems really strange that 3 stacks had the same issue within an hour, Meraki support suggested we hit a bug (8.10) and have requested I upgrade to 9.19.
Has anyone else been having stacking issues?
I typically put in Cisco 4500's or 3850's and these are my first 3 MS350 stack closets. This obviously isn't giving me a very warm and fuzzy feeling to have a failure like this after a month or so.
Curious what other users experiences have been when using MS350 stacks ???
