Chapter 7 Managing Switch Stacks
Understanding Stacks
If you add a provisioned switch that is a different type than specified in the provisioned configuration to
a powered-down switch stack and then apply power, the switch stack rejects the (now incorrect) switch
stack-member-number provision type global configuration command in the startup configuration file.
However, during stack initialization, the nondefault interface configuration information in the startup
configuration file for the provisioned interfaces (potentially of th e wrong type) are executed. Depending
on how different the actual switch type is from the previously provisioned switch type, some command s
are rejected, and some commands are accepted.
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.
The stack member number of
the provisioned switch is in
conflict with an existing stack
member.
The stack master assigns a new stack member
number to the provisioned switch.
The stack member numbers and the switch types
match:
1. If the new 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 provisioned configuration is changed
to reflect the new information.
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 of
the provisioned switch is not
found in the provisioned
configuration.
The switch stack applies the default
configuration to the provisioned switch
and adds it to the stack.
