System Concepts

Active Configurations

The system has two configuration memories:

 Running configuration (RAM)

 Startup configuration (NVRAM)

The system operates based on the settings in the running configuration memory

(RAM). This configuration may or may not be the same as the configuration in

NVRAM. All configuration changes made through any of the user interfaces (CLI,

web interface, NMS) are stored only in the running configuration area. You must

explicitly copy the Running configuration to the Startup configuration.

Multiple users are permitted to be in the configuration mode at the same time, on

all three interfaces. If any of the users perform a save command, then the

configuration changes made by all the users will be saved to the startup

configuration.

System Terminology
