Saving the Configuration After Installing or Exchanging a Module

The following cases automatically result in a change to the running-configuration on your switch:

■If you replace a module with another module of a different type and then reboot the switch

■If you install a module in a slot that has not previously been used (including when you install a module and apply power to the switch for the first time)

If you want to save such changes to permanent memory (startup-configuration), use the write memory command in the switch console. This causes the switch to use the new hardware configuration for subsequent reboots. (The switch always reboots from the startup-configuration.)

If you do not save the hardware changes to the startup-configuration, you will be prompted with the following message the next time you use the reboot or reload commands:

Do you want to save the current configuration [y/n]?

For more information on switch memory, including the startup-config and running-config memories, refer to the Management and Configuration Guide for your switch. See “View or Download the Manual Set” on page 1.
