File Transfers
Downloading Switch Software
Using Auto-TFTP
The auto-tftp command allows you to configure the switch to download
software automatically from a TFTP server.
How It Works. At switch startup, the auto-TFTP feature automatically
downloads a specified software image to the switch from a specified TFTP
server, then reboots the switch. To implement the process, you must first
reboot the switch using one of the following methods:
â– enter the boot system flash primary command in the CLI
â– with the default flash boot image set to primary flash (the default), enter
the boot or the reload command, or cycle the power to the switch. (To reset
the boot image to primary flash, use boot set-default flash primary.)
Syntax:
auto-tftp <ip-addr > <filename >
By default, auto-TFTP is disabled. This command
configures the switch to automatically download the
specified software file from the TFTP server at the specified
IP address. The file is downloaded into primary flash
memory at switch startup. The switch then automatically
reboots from primary flash.
Notes: To enable auto-TFTP to copy a software image to
primary flash memory, the version number of the down-
loaded software file (for example, K_14_01.swi) must be
different from the version number currently in the
primary flash image.
The current TFTP client status (enabled or disabled)
does not affect auto-TFTP operation. (Refer to “Enabling
TFTP” on page A-9.)
Completion of the auto-TFTP process may require
several minutes while the switch executes the TFTP
transfer to primary flash, and then reboots again.
The no form of the command disables auto-TFTP operation
by deleting the auto-tftp entry from the startup configuration.
The no auto-tftp command does not affect the current TFTP-
enabled configuration on the switch. However, entering the
ip ssh filetransfer command automatically disables both auto-
tftp and tftp operation.
