Cisco 3750 Redundancy Test

The Cisco 3750 Catalyst Series offer high class switching functionality such as StackWise support with a 32 Gbit dual ring (16+16G). This means that you have a 32 Gigabit throughtput between Stack Switches.

During some testing with 2 stacked switches, I was able to simulate a failure by issuing the command:

reload slot 2 -> This will reload the module 2 switch.

switch# reload ?
LINE Reason for reload
at Reload at a specific time/date
cancel Cancel pending reload
in Reload after a time interval
slot Slot number card
standby-cpu Standby RP
