CAUTION: Do not download a configuration file from one switch to another switch that is a different model or firmware version, because it can cause the switch to fail. If you need to reset affected switches, enter the configDefault command. IMPORTANT: Verify that all domain IDs are unique prior to performing the configDownload because the switches will segment if they all have the same domain ID. If you download an existing configuration file to a switch that has a different interoperable mode setting, the configDownload command will fail. You must first change the switch's interoperable mode to equal that of the configuration file, reboot the switch, and then re-download the configuration file. Downloading a configuration file from one switch to another same model switch 1. Configure one switch. 2. Use the configUpload command to save the configuration information. See "Configuration file backup" on page 165 for more information. 3. Run configDefault on each of the target switches, and then use the configDownload command to download the configuration file to each of the target switches. See "Configuration file restoration" on page 166 for more information. Security considerations Security parameters and the switch's identity cannot be changed by the configDownload command. Parameters such as the switch name and IP address (lines in the configuration file that begin with boot) are ignored. Security parameters (lines in the configuration file that begin with sec), such as secure mode setting and version stamp, are ignored. For more detailed information on security, see Chapter 3, "Configuring standard security features" on page 99. Configuration restoration in a FICON environment If the switch is operating in a FICON CUP environment, and the ASM (active=saved) bit is set on, the switch ignores the IPL file downloaded when you restore a configuration. Table 47 describes this behavior in more detail. Table 47 Backup and restore in a FICON CUP environment ASM bit Command Description on or off on configUpload configDownload All the files saved in the file access facility are uploaded to the management workstation. A section in the uploaded configuration file labeled FICON_CUP is in an encoded format. Files saved on the switch that are also present in the FICON_CUP section of the configuration file are overwritten. Files in the FICON section of the configuration file that are not currently present on the switch are saved. The IPL file is replaced, because active=saved mode is on. A warning message is displayed in the syslog to warn that the IPL file is not being overwritten. off configDownload Files saved on the switch that are also present in the FICON_CUP section of the configuration file are overwritten. Files in the FICON section of the configuration file that are not currently present on the switch are saved. The IPL file is not replaced, because active=saved mode is off.
