480T routing switch firmware image. It also includes a
discussion of how to save and load a primary and secondary image and
configuration file on the switch.
Saving Configuration Changes
The configuration is the customized set of parameters that you have
selected to run on the switch. As you make configuration changes, the new
settings are stored in run-time memory. Settings that are stored in run-
time memory are not retained by the switch when the switch is rebooted.
To retain the settings and have them load when you reboot the switch, you
must save the configuration to non-volatile (more permanent) storage.
The switch can store two different configurations: a primary and a
secondary. When you save configuration changes, you can select the
configuration you want to save the changes to. If you do not specify, the
changes are saved to the configuration area currently in use.
