Erasing image and configuration files 7 NOTE Command option 23 adds configuration information to the running-config on the device, and does not replace commands. If you want to replace configuration information in the device, use "no" forms of the configuration commands to remove the configuration information, then use configuration commands to create the configuration information you want. Erasing image and configuration files To erase software images or configuration files, use the commands described below. These commands are valid at the Privileged EXEC level of the CLI: • erase flash primary erases the image stored in primary flash of the system. • erase flash secondary erases the image stored in secondary flash of the system. • erase startup-config erases the configuration stored in the startup configuration file; however, the running configuration remains intact until system reboot. File synchronization This section provides details for synchronizing the files on the management and interface modules. File synchronization between the active and standby management modules Each active and standby management module contains the following files that can be synchronized between the two modules: • Flash code - The flash code can include the following files: • monitor, which contains the management module's Real Time Operating System (RTOS). • primary, which contains the management module's primary IronWare image. • secondary, which contains the management module's secondary IronWare image. (An IronWare image contains the layer 1 - 3 software run by the management module.) During startup or switchover, the active module compares the standby module's flash code to its own. If differences exist, the active module synchronizes the standby module's flash code with its own. If you update the flash code on the active module, the active module automatically synchronizes (without comparison) the standby module's flash code with its own. • System-config file - The flash code also includes the system-config file. During startup or switchover, the active module compares the standby module's system-config file to its own. If differences exist, the active module synchronizes the standby module's system-config file with its own. When you save changes to the system-config file on the active module, the active module automatically synchronizes (without comparison) the standby module's system-config file with its own. • Running-config - The running-config file resides in the BigIron RX Series system memory. The BigIron RX Series switches allow you to do the following related to file synchronization: • Compare files on the active module with files on the standby module and immediately synchronize any files that are different.
