Naming a Stack Unit

You can assign names to stack units to help identify them. Stack unit names can be up to 63 characters long. A stack unit name must start with an alpha character and must not contain spaces.
Perform these steps to assign a name to one or more stack members.
  1. Enter global configuration mode. 
    device# configure terminal
  2. Enter the stack unit command followed by the number of the stack unit you want to name. 
    device(config)# stack unit 1
    The device enters stack unit configuration mode.
  3. Enter the unit-name command followed by the name that you want to represent the unit in configuration output. 
    device(config-unit-1)# unit-name operations
    The example assigns the name operations to stack unit 1.
  4. (Optional) Repeat steps 3 and 4. You can repeat this step as many times as needed. 
    device(config-unit-1)# stack unit 2
device(config-unit-2)# unit-name engineering
    The example enters stack unit configuration mode for unit 2 and assigns the name engineering to the unit.
  5. When you are finished naming units, enter the write memory command in Privileged Exec mode to save the configuration. 
    device(config-unit-2)# end
device# write memory

The following example assigns names to the members of a three-unit stack, based on the building they support. 

device# configure terminal
device(config)# stack unit 1
device(config-unit-1)# unit-name building1
device(config-unit-1)# stack unit 2
device(config-unit-2)# unit-name building2
device(config-unit-2)# end
device# write memory
