Effects of Replacing a Preconfigured Switch in a Switch Stack
When a preconfigured switch in a switch stack fails, is removed from the stack, and is replaced
with another switch, the stack applies either the preconfiguration or the default configuration to it.
The events that occur when the switch stack compares the configuration with the preconfigured
switch are the same as those described in “Effects of Adding a Preconfigured Switch to a Switched
Stack”.
Effects of Removing a Preconfigured Switch from a Switch Stack
If you remove a preconfigured switch from the switch stack, the configuration associated with the
removed stack member remains in the running configuration as configured information. To
completely remove the configuration, use the no member unit_number (this is in the stacking
configuration mode).
Table 20-1. Results of comparing the preconfiguration with the new switch
Scenario Result
The stack member numbers and the switch types
match.
• If the stack member number of the preconfigured
switch matches the stack member number in the
configuration on the stack, and
• If the switch type of the preconfigured switch
matches the switch type in the configuration on the
stack.
The switch stack applies the configuration to the
preconfigured new switch and adds it to the stack.
The stack member numbers match but the switch
types do not match.
• If the stack member number of the preconfigured
switch matches the stack member number in the
configuration on the stack, but
• The switch type of the preconfigured switch does
not match the switch type in the configuration on
the stack.
• The switch stack applies the default configuration
to the preconfigured switch and adds it to the stack.
• The configuration in the preconfigured switch is
changed to reflect the new information.
The stack member number is not found in the
configuration.
• The switch stack applies the default configuration
to the new switch and adds it to the stack.
• The preconfigured information is changed to reflect
the new information.
The stack member number of the preconfigured
switch is not found in the configuration.
The switch stack applies the default configuration to
the preconfigured switch and adds it to the stack.
