168 Maintaining the switch configuration file
In case something happens to your switch and you need to set it up again, run the commands listed in
Table 46 and save the output in a file format. Store the files in a safe place for emergency reference.
CAUTION: 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 or Fabric Watch parameters. However, if there is any changed
parameter that does not belong to SNMP or Fabric Watch, you must disable the switch. When you use the
configDownload
command, you are prompted to disable the switch only when necessary.
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.
IMPORTANT:
In Fabric OS 6.2, the configuration download process can restore only Logical Switches that
already exist and with the same FIDs. It cannot be used to clone or repair the current switch because the
configDownload
command cannot create Logical Switches if they do not exist.
Restoring a configuration
1. Verify that the FTP service is running on the server where the backup configuration file is located.
2. Connect to the switch and log in as admin.
3. If there are any changed parameters in the configuration file that do not belong to SNMP, Fabric
Watch, or ACL, disable the switch by entering the
switchDisable
command.
4. Enter the
configDownload
command.
The command becomes interactive and you are prompted for the required information.
