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, MAPS, Fabric Watch, or ACL parameters. However, if there is any changed parameter that does not belong to SNMP, MAPS, or
ACL, then you must disable the switch. When you use the configDownload command, you are prompted to disable the switch
only when
necessary
.
ATTENTION
The configuration download process can restore only logical switches that already exist and that use 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 the SFID 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 with admin permissions, and if necessary, with chassis permissions.
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 .
Wait for the configuration to be restored.
6. If you disabled the switch, enter the switchEnable command when the process is finished.
NOTE
Always perform a reboot after you download a configuration file. On dual-CP platforms, you must reboot both CPs
simultaneously.

*** CAUTION ***
This command is used to download a backed-up configuration
for a specific switch. If using a file from a different
switch, this file's configuration settings will override
any current switch settings. Downloading a configuration
file, which was uploaded from a different type of switch,
may cause this switch to fail.
A switch reboot is required for the changes to take effect.
Please make sure all the switches are disabled by
using "chassisdisable" command. Downloading configuration
to an online switch may result in some configuration not
being downloaded to that switch.
configDownload operation may take several minutes
to complete for large files.
