The interface-specific settings of the active switchstack master are saved if the active switchstack master
is replaced without saving the running configuration to the startup configuration. Note
A new, out-of-box switch joining a switch stack uses the system-level settings of that switch stack. If a switch
is moved to a different switch stack before it is powered on, that switch loses its saved configuration file and
uses the system-level configuration of the new switch stack. If the switch is powered on as a standalone switch
before it joins the new switch stack, the stack will reload. When the stack reloads, the new switch may become
the active switchstack master, retain its configuration and overwrite the configuration files of the other stack
members.
The interface-specific configuration of each stack member is associated with the stack member number. Stack
members retain their numbers unless they are manually changed or they are already used by another member
in the same switch stack. If the stack member number changes, the new number goes into effect after that
stack member resets.
• If an interface-specific configuration does not exist for that member number, the stack member uses its
default interface-specific configuration.
• If an interface-specific configuration exists for that member number, the stack member uses the
interface-specific configuration associated with that member number.
If you replace a failed member with an identical model, the replacement member automatically uses the same
interface-specific configuration as the failed switch. You do not need to reconfigure the interface settings.
The replacement switch (referred to as the provisioned switch) must have the same stack member number as
the failed switch.
You back up and restore the stack configuration in the same way as you would for a standalone switch
configuration.
Offline Configuration to Provision a Stack Member
You can use the offline configuration feature to provision (to supply a configuration to) a new switch before
it joins the switch stack. You can configure the stack member number, the switch type, and the interfaces
associated with a switch that is not currently part of the stack. The configuration that you create on the switch
stack is called the
provisioned configuration . The switch that is added to the switch stack and that receives
this configuration is called the provisioned switch .
You manually create the provisioned configuration through the switch stack-member-number provision type
global configuration command. You must change the stack-member-number on the provisioned switch before
you add it to the stack, and it must match the stack member number that you created for the new switch on
the switch stack. The switch type in the provisioned configuration must match the switch type of the newly
added switch. The provisioned configuration is automatically created when a switch is added to a switch stack
and when no provisioned configuration exists.
When you configure the interfaces associated with a provisioned switch, the switch stack accepts the
configuration, and the information appears in the running configuration. However, as the switch is not active,
any configuration on the interface is not operational and the interface associated with the provisioned switch
does not appear in the display of the specific feature. For example, VLAN configuration information associated
with a provisioned switch does not appear in the
show vlan user EXEC command output on the switch stack.
The switch stack retains the provisioned configuration in the running configuration whether or not the
provisioned switch is part of the stack. You can save the provisioned configuration to the startup configuration
file by entering the
copy running-config startup-config
privileged EXEC command. The startup configuration
