Purging the Module Configuration
Purging the Module Configuration
To delete the configuration in an empty slot or in a slot with a powered-down I/O module, use the purge
module slot running-config command from EXEC mode. This command clears the running
configuration for the specified slot. This command does not work on supervisor modules or on any slot
that currently has a powered-up module. This command only works on an empty slot (where the
specified module once resided) or on a slot with a powered-down I/O module.
The purge module command clears the configuration for any module that previously existed in a slot
and has since been removed or powered down. 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 you clear that from the running configuration.
For example, suppose you create an IP storage configuration with a 48-port 10/100/1000 Ethernet
module in slot 3 in Device A. This module uses IP address 10.1.5.500. You decide to remove this I/O
module and move it to Device B, and you no longer need the IP address 10.1.5.500. If you try to
configure this unused IP address, you will receive an error message that prevents you from proceeding
with the configuration. In this case, you need to enter the purge module 3 running-config command to
clear the old configuration in Device A before using this IP address.
Powering Off I/O Modules
By default, all fabric modules are configured to be in the power up state.
