Select the required function and input the path and filename of the file the switch
attempts to download or upload, as it is to be received and interpreted by the TFTP
server. (The security mode in use on the TFTP server may affect this function.)
➽ Note:
By using
Download VLAN
’s default gateway, if it has one, the file can be
downloaded from another network anywhere on the Internet from which the VLAN
can get packets routed (even another directly connected VLAN). In the latter case,
the switch will actually load, or attempt to load, through the gateway and not ignore
its
Download Domain
parameter. If the switch is unable to reach a TFTP server to
which it should have a direct or indirect route, an incorrectly set
Download VLAN
may be the reason.
Execute <name> Download/Upload
This command is displayed on the sub-screens that are opened from the
TFTP
Download/Upload
screen.
The command
Execute <name> Download/Upload
initiates the download or
upload for a single switch only. The screen displays the block it last received from
the server (block 0 if no reply has been received) until the last packet arrives. The
switch does not attempt to load any of the image into flash memory until it receives
the final packet. Therefore, if interrupted or cancelled for any reason before the last
packet, the previous system image remains intact in flash memory.
Once the last packet has arrived, the switch immediately begins clearing flash
memory and loads it with the new image.
The switch will continue to use its previously loaded software until its next reset by
whatever means. The newly stored image is not functional until a reset is
performed.
➽ Note:
Be careful - if the process is interrupted during this time, the stored image
may be corrupted and the switch will not be able to boot normally! If this happens,
it is necessary to download the switch via its Out-of-Band Management port since
the system boot image does not contain software capable of operating the network
hardware of the switch or understanding IP and TFTP protocols. During this fairly
short vulnerable period of time, the diagnostic LED on the switch blinks to indicate
the clearing (slow blink) and reloading (faster blink) of flash memory. The screen
also displays messages indicating these events.
