Brocade Communications Systems S3-1002483-03 manual Logging changes to the startup-config file

6 Loading and saving configuration files

•Running configuration – This active configuration is in the system RAM but not yet saved to code flash. These changes could represent a short-term requirement or general configuration change. To display this configuration, enter the show running-configor write terminal command at any CLI prompt.

Each device can have one startup configuration file and one running configuration. The startup configuration file is shared by both flash modules. The running configuration resides in DRAM.

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 code flash. When you write configuration changes to code flash, 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:

BigIron RX# 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:

BigIron RX# reload

When the system detects differences between the running and startup configurations, it prompts you as follows:

Are you sure? (enter ‘y’ or ‘n’):

Enter y, and press the Enter key.

Logging changes to the startup-config file

You can configure a BigIron RX Series 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 at the global CONFIG level of the CLI:

Syntax: [no] logging enable config-changed
