Loading and saving configuration files

For easy configuration management, all Brocade devices support both the download and upload of
configuration files between the devices and a TFTP server on the network.
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.
device# write memory
NOTE
To return the unit to the default startup configuration, use the delete startup-config command.
