Fabric OS 6.1.x administrator guide 145
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.

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.
