Brocade Communications Systems 6650 manual Logging changes to the startup-config file

3 Loading and saving configuration files

•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-configor 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-maxcommands. A system-maxcommand changes the size of statically configured memory.

2.During the second pass, the parser implements the system-maxcommands 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.

Brocade#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.

Brocade#reload

Logging changes to the startup-config file

You can configure a Brocade 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>

To disable or re-enable Syslog messages when the startup-config file is changed, use the following command.

Syntax: [no] logging enable config-changed
