Stacking Standby
The stacking feature supports a
Standby
or backup unit that assumes the
Master unit role if the Master unit in the stack fails. As soon as a Master
failure is detected in the stack, the Standby unit initializes the control plane
and enables all other stack units with the current configuration. The Standby
unit maintains a synchronized copy of the running configuration for the
stack. The Standby unit is automatically selected in the stack; however, you
can use the CLI to select a different stack member as Standby. See the
User’s
Configuration Guide
or the
CLI Reference Guide
for more information.
