Chapter 6 Managing Switch Stacks
Understanding Stacks
Stack Offline Configuration
You can use the offline configuration feature to provision (to configure) a new switch before it joins the
stack. You can configure the member number, the switch type, and the interfaces associated with a switch
that is not yet part of the stack. That configuration is the
provisioned configuration . The switch to be
added to the stack and to get this configuration is the provisioned switch .
The provisioned configuration is automatically created when a switch is added to a stack and when no
provisioned configuration exists. You can manually create the provisioned configuration by using the
switch stack-member-number provision type global configuration command.
When you configure the interfaces for a provisioned switch (for example, as part of a VLAN), the
information appears in the stack running configuration whether or not the provisioned switch is part of
the stack. The interface for the provisioned switch is not active and does not appear in the display of a
specific feature (for example, in the
show vlan user EXEC command output). Entering the no shutdown
interface configuration command has no effect.
The startup configuration file ensures that the stack can reload and can use the saved information
whether or not the provisioned switch is part of the stack.
Effects of Adding a Provisioned Switch to a Stack
When you add a provisioned switch to the switch stack, the stack applies either the provisioned
configuration or the default configuration to it.
Table 6-1 lists the events that occur when the switch stack
compares the provisioned configuration with the provisioned switch.
Table 6-1 Results of Comparing the Provisioned Configuration with the Provisioned Switch
Scenario Result
The stack member numbers and
the switch types match.
1.
If the stack member number of the
provisioned switch matches the stack
member number in the provisioned
configuration on the stack, and
2. If the switch type of the provisioned switch
matches the switch type in the provisioned
configuration on the stack.
The switch stack applies the provisioned
configuration to the provisioned switch
and adds it to the stack.
The stack member numbers
match but the switch types do
not match.
1.
If the stack member number of the
provisioned switch matches the stack
member number in the provisioned
configuration on the stack, but
2.
The switch type of the provisioned switch
does not match the switch type in the
provisioned configuration on the stack.
The switch stack applies the default
configuration to the provisioned switch
and adds it to the stack.
The provisioned configuration is changed
to reflect the new information.
The stack member number is
not found in the provisioned
configuration. The switch stack applies the default
configuration to the provisioned switch
and adds it to the stack.
The provisioned configuration is changed
to reflect the new information.
