CLI – Enter the following command.
Managing Firmware
You can upload/download firmware to or from a TFTP server. Just specify the method of
file transfer, along with the file type and file names as required. By saving runtime code to
a file on a TFTP server, that file can later be downloaded to the switch to restore
operation.
Only one copy of the system software (i.e., the runtime firmware) can be stored in the file
directory on the switch. When downloading runtime code, the new firmware file will
therefore overwrite the existing file.
Command Attributes
• File Transfer Method – The firmware copy operation includes these options:
- file to file – Copies a file within the switch directory, assigning it a new name.
- file to tftp – Copies a file from the switch to a TFTP server.
- tftp to file – Copies a file from a TFTP server to the switch.
• TFTP Server IP Address – The IP address of a TFTP server.
• File Type – Specify opcode (operational code) to copy firmware.
• File Name –
The file name should not contain slashes (\ or /), the leading letter of the file
name should not be a period (.), and the maximum length for file names on the TFTP
server is 127 characters or 31 characters for files on the switch. (Valid characters: A-Z,
a-z, 0-9, “.”, “-”, “_”)
Note:
Transferring a new operation code file to the switch will overwrite the existing file.
Versions of the code prior to 1.1.0.10 require the operation code file being transferred to
have the same destination file name as the existing code file for the transfer to succeed.
