Managing Firmware
You can upload/download firmware to or from a TFTP server, or copy
files to and from switch units in a stack. By saving runtime code to a file on
a TFTP server, that file can later be downloaded to the switch to restore
operation. You can also set the switch to use new firmware without
overwriting the previous version. You must specify the method of file
transfer, along with the file type and file names as required.
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.
- file to unit – Copies a file from this switch to another unit in the stack.
- unit to file – Copies a file from another unit in the stack to this 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, “.”,
“-”, “_”)
• Source/Destination Unit – Stack unit. (Range: 1 - 8)
Note: Up to two copies of the system software (i.e., the runtime
firmware) can be stored in the file directory on the switch. The
currently designated startup version of this file cannot be deleted.
