User Guidelines
This command is not relevant to standalone devices.
The following algorithm is used to select a unit as the master:
• If only one master-enabled unit is in the stack (1 or 2), it becomes the master.
• If a unit configured as a forced master, it becomes the master.
If a forced master unit is removed from a stack and placed in a different stack with another forced master unit, both
are considered to be forced, and the election criteria continue as follows:
• The unit with the longer up-time is elected master. Units are considered to have the same up-time if they were
powered up within ten minutes of each other.
• If both forced master units have the same up-time, Unit 1 is elected.
Example
The following example selects Unit 2 as the stack master.
stack reload
The stack reload Privileged EXEC mode command reloads stack members.
console(config)# hostname stack
stack(config)#
no hostname
console(config)#
console(config)#
stack master unit 2
