Purging Module Configurations; Powering Off Switching Modules - Cisco MDS 9000 Series Configuration Manual

Managing Modules

Purging Module Configurations

Enter the purge module slot running-config command to delete the configuration in a specific module. Once
you enter this command, the Cisco NX-OS software clears the running configuration 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 you clear it 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 will receive an
error message that prevents you from proceeding with the configuration. In this case, you must enter the purge
module 3 running-config command to clear the old configuration on Switch A before proceeding with using
this IP address.

Powering Off Switching Modules

You can power off a switching module from the command-line interface (CLI). By default, all switching
modules are in the power up state when the chassis loads or you insert the module into the chassis.
