This step ensures that any configuration you have made can survive a reboot.

2. Specify main startup images for the device and perform a warm reboot.

  • Use an .ipe file for upgrade:warm-reboot [ file ipe ipe-filename ]

  • Use .bin files for upgrade:warm-reboot [ file { boot boot-package | system system-package | feature feature-package&<1-30> } ]

Upgrade files must be saved in the root directory of the storage medium.

If the storage medium is partitioned, save the files to the root directory of the first partition.

If you do not specify upgrade files, the switch reboots without upgrading software.

3. (Optional.) Verify the software image settings.
