stack master
The stack master Global Configuration mode command enables forcing the selection of a stack
master. Use the no form of this command to return to the default configuration.
Syntax
• stack master unit unit
• no stack master
• unit — Unit number of the new master (Range: 1 - 2)
Default Configuration
Disables forcing the selection of a stack master.
Command Mode
Global Configuration mode.
User Guidelines
• 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.
Syntax
• stack reload [ unit ]
•
unit — Number of the unit to be reloaded (Range: 1 - 8)
Console(config)# stack master unit 2
