Scenario
A particular switching module is removed and the copy
running-config startup-config command is issued again.
A particular switching module is removed and the same
switching module is replaced before the copy
running-config startup-config command is issued again.
A particular switching module is removed and replaced
with the same type switching module, and a reload
module number command is issued.
A particular switching module is reloaded when a reload
module number command is issued.
A particular switching module is removed and replaced
with a different type of switching module. For example, a
16-port switching module is replaced with a 32-port
switching module.

Purging Module Configuration
Issue the purge module slot running-config command from EXEC mode to delete the configuration in
a specific module. Once this command is issued, the running configuration is cleared for the specified
slot. This command does not work on supervisor modules or on any slot that currently has a module.
This command only works on an empty slot (where the specified module once resided).
The purge module command clears the configuration for any module that previously existed in a slot
and has since been removed. While the module was in that slot, some parts of the configuration may have
been stored in the running configuration and cannot be reused (for example, IP addresses), unless it is
cleared from the running configuration.
For example, suppose you create an IP storage configuration with an IPS module in slot 3 in Switch A.
This module uses IP address 10.1.5.500. You decide to remove this IPS module and move it to Switch
B, and you no longer need the IP address10.1.5.500. If you try to configure this unused IP address, you

Switching Module Configuration Status
The switch currently has a 16-port switching module
and the startup and running configuration files are the
same.
You replace the 16-port switching module in the
switch with a 32-port switching module.
Next, you remove the 32-port switching module and
replace it with the same 16-port switching module
referred to in Step 1.
You reload the switch.

Consequence
The configured module information is lost.
The configured module information is
preserved.
The configured module information is
preserved.
The configured module information is
preserved.
The configured module information is lost
from the running configuration. The
default configuration is applied.
The configured module information
remains in startup configuration until a
copy running-config startup-config
command is issued again.
Sample response:
The switch uses the 16-port switching

module and the present configuration
is saved in nonvolatile storage.
