Configuration file restoration

CAUTION
The switch has limited 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, or ACL parameters. However, if there
is any changed parameter that does not belong to SNMP, Fabric Watch, or ACL, then you must
disable the switch. When you use the configDownload command, you will be 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 v6.1.0 and later.
ATTENTION
In Fabric OS v6.2.0 and later, the configuration download process can only restore 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

CAUTION
Using the SFID parameter erases all configuration information on the logical switch.
Use this parameter only when the logical switch has no configuration information you want to
save.
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 using an account assigned to the admin role, and if necessary
with the chassis-role permission.
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.
5. At the “Do you want to continue [y/n]” prompt, enter y.
6. Wait for the configuration to be restored.
7. If you disabled the switch, enter the switchEnable command when the process is finished.
NOTE
Because some configuration parameters require a reboot to take effect, after you download a
configuration file, you must reboot to be sure that the parameters are enabled. Before the reboot,
this type of parameter is listed in the configuration file, but it is not effective until after the reboot.
