i have x440-48T Switch stacks in my Local LAN, over the last 6 months the LAN has been brought to a standstill because of a failure on a stack, both times it was a different stack. No one can connect from external the whole Network is down. We have LACP enabled on all stacks.
The error what i see is this, anfter a reboot of the stack ist is good again but i dont understand why one failed Switch will bring the whole Network to a standstill.
