Describes the methods for upgrading device software using TFTP. This feature supports both automated and manual retrieval processes to ensure devices remain updated with the latest images.
Automatic Device Upgrade using TFTP
Upgrades the device image automatically by connecting to a local TFTP server at user-defined intervals. The device detects the image file and performs the upgrade process.
Direct Device Upgrade using TFTP
Describes the process for upgrading a device image directly from a TFTP server. This method allows administrators to specify the server IP and image file to initiate an immediate firmware update.
TFTP Device Upgrade using CLI
