There are two possible methods for this. The first method involves generating a Xos Scripting File (.xsf) from the configuration. The second method will upload the actual configuration file (.cfg), in XML format, from the switch.
Method 1: Create a .xsf script from the current config
On the switch, use the upload config command to upload an EXOS CLI script to a TFTP server and ensure the virtual router is specified. This script will be the same as the output of show config. In this example, the script is called config.xsf. However, the filename does not matter, as long as the extension is .xsf.
X460G2-24p-G4.6 # upload config 192.0.2.156 config.xsf <vr-name>
Uploading config.xsf to 192.0.2.156 ... done!
1. To restore the config from this backup, use the tftp get command to download the script.
X460G2-24p-G4.7 # tftp get 192.0.2.156 <vr-name> config.xsf
Downloading config.xsf to switch... done!
2. Run the script with the load script command.
X460G2-24p-G4.8 # load script config
Note: Loading an .xsf script on a switch with non-default configuration may lead to command conflicts. When restoring a backup configuration using an .xsf file it is usually best to clear the switch configuration and load the script on top of the default configuration.

Method 2: Upload the .cfg configuration file
1. Use the show switch command to see what the currently selected configuration file is.
X460G2-24p-G4.8 # show switch

2. Upload that file to a TFTP server with the tftp put command.
X460G2-24p-G4.9 # tftp put 192.0.2.156 <vr-name> primary.cfg
Uploading primary.cfg to 192.0.2.156 ... done!
1. To restore the config, download the config file with the tftp get command.
X460G2-24p-G4.10 # tftp get 192.0.2.156 <vr-name> primary.cfg
/usr/local/cfg/primary.cfg already exists, do you want to overwrite it? (y/N) Yes
Downloading primary.cfg to switch..... done!
2. Select this file to be used as the config on the next reboot.
X460G2-24p-G4.11 # use config primary
The selected configuration will take effect after the next switch reboot.
3. Reboot the switch to boot to the new config file. When prompted, DO NOT save the config. Saving the config at this point will overwrite the newly selected config file.
X460G2-24p-G4.12 # reboot
Do you want to save configuration changes to currently selected configuration
file (primary.cfg) and reboot?
(y - save and reboot, n - reboot without save, <cr> - cancel command) No
