Loading and saving configuration files
3
You can upload either the startup configuration file or the running configuration file to the TFTP
server for backup and use in booting the system:
• Startup configuration file – This file contains the configuration information that is currently
saved in flash. To display this file, enter the show configuration command at any CLI prompt.
• Running configuration file – This file contains the configuration active in the system RAM but
not yet saved to flash. These changes could represent a short-term requirement or general
configuration change. To display this file, enter the show running-config or write terminal
command at any CLI prompt.
Each device can have one startup configuration file and one running configuration file. The startup
configuration file is shared by both flash modules. The running configuration file resides in DRAM.
When you load the startup-config file, the CLI parses the file three times.
1. During the first pass, the parser searches for system-max commands. A system-max
command changes the size of statically configured memory.
2. During the second pass, the parser implements the system-max commands if present and also
implements trunk configuration commands (trunk command) if present.
3. During the third pass, the parser implements the remaining commands.
Replacing the startup configuration with the
running configuration
After you make configuration changes to the active system, you can save those changes by writing
them to flash memory. When you write configuration changes to flash memory, you replace the
startup configuration with the running configuration.
To replace the startup configuration with the running configuration, enter the following command
at any Enable or CONFIG command prompt.
PowerConnect# write memory
Replacing the running configuration with the
startup configuration
If you want to back out of the changes you have made to the running configuration and return to
the startup configuration, enter the following command at the Privileged EXEC level of the CLI.
PowerConnect# reload
Logging changes to the startup-config file
You can configure a device to generate a Syslog message when the startup-config file is changed.
The trap is enabled by default.
The following Syslog message is generated when the startup-config file is changed.
startup-config was changed
If the startup-config file was modified by a valid user, the following Syslog message is generated.
startup-config was changed by <username>
