i've gout a question regarding catalyst 3750 stack software upgrades.
is there any possibility to do a software upgrade to the stack without rebooting all stack
members at the same time?
i tried to do this manually with "archive download-sw /overwrite"
(without using /force-reload or /reload parameters) and then reboot one of the two members
in the stack. the remaining switch correctly becomes the Master. But when the member with the
new software comes up again, a version missmatch is detected (by the switch running the old sowftware) and the upcomming switch stucks in the boot process.
so everything i tried, i've got a network down for the whole stack.
we have a scenario where servers are connected to both members of a stack (for REDUNDANCY and
bandwidth aggregation). it would be nice if' there's any procedure to do an upgrade in the stack without
losing both connections to our servers at the same time...
