switch.

To confirm that the software downloaded correctly, execute
show system
and check the
Firmware revision
line.
For information on primary and secondary flash memory and the boot commands, see "Using Primary and
Secondary Flash Image Options" in the basic operation guide for your switch.
NOTE:
If you use
auto-tftp
to download a new image in a redundant management system, the
active management module downloads the new image to both the active and standby modules.
Rebooting after the
auto-tftp
process completes reboots the entire system.
Enabling TFTP (CLI)
TFTP is enabled by default on the switch. If TFTP operation has been disabled, you can re-enable it by specifying
TFTP client or server functionality with the
tftp [client|server]
command at the global configuration level.
Syntax:
[no] tftp [client | server]
Disables/re-enables TFTP for client or server functionality so that the switch can:
• Use TFTP client functionality to access TFTP servers in the network to receive downloaded files.
• Use TFTP server functionality to upload files to other devices on the network.
NOTE:
Usage notes
To disable all TFTP client or server operation on the switch except for the auto-TFTP feature, enter
the
no tftp [client|server]
command.
When IP SSH file transfer is used to enable SCP and SFTP functionality on the switch, this disables
TFTP client and server functionality. Once ip ssh file transfer is enabled, TFTP and auto-TFTP
cannot be re-enabled from the CLI.
When TFTP is disabled, instances of TFTP in the CLI
copy
command and the Menu interface
"Download OS" screen become unavailable.
The
no tftp [client|server]
command does not disable auto-TFTP operation. To disable an
auto-TFTP command configured on the switch, use the
no auto-tftp
command to remove the
command entry from the switch's configuration.
For information on how to configure TFTP file transfers on an IPv6 network, see the "IPv6
Management Features" in the IPv6 configuration guide for your switch.
Configuring the switch to download software automatically from a TFTP server using
auto-TFTP (CLI)
The
auto-tftp
command lets you configure the switch to download software automatically from a TFTP server.
At switch startup, the auto-TFTP feature automatically downloads a specified software image to the switch from a
specified TFTP server and then reboots the switch. To implement the process, you must first reboot the switch
using one of the following methods:
