Restoring a configuration Restoring a configuration involves overwriting the configuration on the switch by downloading a previously saved backup configuration file. Make sure that the configuration file you are downloading is compatible with your switch model, because configuration files from other model switches might cause your switch to fail. The configuration download process is additive, that is, the lines read from the files are added to the current switch configuration. You can change a single configuration variable by downloading a file with that specific variable only. When you do so, all other variables remain unchanged. If a configupload command is issued on a non-FCR platform, such as the configuration file from an 400 MP Router, FCR-like parameters may be viewed in the uploaded data. This is harmless to the switch and can be ignored. Run the commands listed in Table 44 and save the output in a file format. Store the files in a safe place for emergency reference.

The configuration download process is additive, that is, the lines read from the files are added to the current switch configuration. You can change a single configuration variable by downloading a file with that specific variable only. When you do so, all other variables remain unchanged. NOTE: The switch has no error checking and edited files may become corrupted and can lead to switch failures. Configuration download without disabling a switch You can download configuration files to a switch while the switch is enabled, that is, you do not need to disable the switch for changes in SNMP, Fabric Watch, and ACL parameters. When you use the configDownload command, you will be prompted to disable the switch only when necessary. However, if there is any changed parameter that does not belong to SNMP, Fabric Watch, or ACL, then you must disable the switch. Configuration download without disabling a switch is independent of the hardware platform and supported on all hardware platforms running Fabric OS 5.2.0 and later.
