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.
