Description

This article introduces the procedure used to upgrade a Lenovo switch running ENOS using the CLI.

Solution

1. Establish a connection to the switch and enter privileged mode.
   RS G8124-E>enable
   
   Enable privilege granted.
   RS G8124-E#
   
    
2. Using the copy command and a selected transfer protocol, copy the Boot.imgs file to the boot-image.
   Note: For the examples in this article, TFTP will be used to transfer the file from TFTP server IP 10.10.10.1. The filename will be G8124-8.4.22.0_Boot.imgs.
   RS G8124-E#copy tftp boot address 10.10.10.1 filename G8124-8.4.22.0_Boot.imgs mgta-port
   
   boot kernel currently contains Software Version 8.4.22
   New download will replace boot kernel with file "G8124-8.4.22.0_Boot.imgs"
   from SFTP/FTP/TFTP server 10.10.10.1.

4. When complete, the switch will prompt you to change the boot image to the new image.
   Switch is currently set to boot software image1.
   Do you want to change that to the new image2? [y/n] y
   Next boot will use new software image2.
   
   RS G8124-E#
   
    
5. Restart the switch to apply the image.
   RS G8124-E#reload
   
   Reset will use software "image2" and the active config block.
