3.1 ConfigurationFileArchitecture
The current configuration of the Managed Switch is based on the “running-config” file in the
system RAM.
When the ACA is disconnected, the Managed Switch boots up with “startup-config” file in the non-
volatile RAM (NVRAM), and the “running-config” file is copied from the “startup- config”.
When the ACA with an applicable configuration file is connected, the Managed Switch boots up
with the “switch.cfg” file in the ACA from where the “running-config” and “startup-config” files are
copied.

Command Line Interface (CLI) can modify the “running-config” file in the system RAM.
To save the modification before rebooting, copy the “running-config” file to the “startup-config” file
in the NVRAM.
If this copy command is executed while the ACA is connected, the “running-config” file is
saved as “switch.cfg” in the ACA. (For copying the configuration file, see section “4.3.5 copy”
command.)
Since the ACA is identified as a USB storage device by connecting to a computer, the
configuration file in the ACA is named as “switch.cfg,” a binary format file.
