Managing Files on a Stack Image files downloaded to the primary unit of a stack are automatically downloaded to all stack members. If you activate the backup image on the primary, it is activated on all units as well so that when you reload the stack, all units use the same image. The running-config, startup-config, and backup-config files, as well as all keys and certificates are synchronized across the stack when the running-config file is saved to the startup-config file. Configuration scripts are not distributed across the stack and only exist on the unit that is the primary unit at the time of the file download. Uploading Configuration Files by Using SNMP When you use SNMP to upload a configuration file to a TFTP server, the agentTransferUploadFileName object must be set to the local filename, which is either startup-config or backup-config. How Is the Running Configuration Saved? Changes you make to the switch configuration while the switch is operating are written to the running-config. These changes are not automatically written to the startup-config. When you reload the switch, the startup-config file is loaded. If you reload the switch (or if the switch resets unexpectedly), any settings in the running-config that were not explicitly saved to the startup-config are lost. You must save the running-config to the startupconfig to ensure that the settings you configure on the switch are saved across a switch reset. To save the running-config to the startup-config by using the web-based interface, click (the save icon), which is available at the top of each page. To save the running-config to the startup-config from the CLI, use the write command. Images and File Management 511
