Upgrading Software
Using TFTP
TFTP (Trivial File Transfer Protocol) is a simple file transfer protocol that is used
without complex interaction between clients and servers.
The client initiates a TFTP transmission. To download files, the client sends a read
request packet to the TFTP server, receives the packet from the server, and sends
the acknowledgement to the server. To upload files, the client sends a write
request packet to the TFTP server, sends the data packet to the server, and receives
the acknowledgement from the server.
The Switch 7700 provides the functions of the TFTP client.
A TFTP Server program is shipped on the CDROM with the Switch 7700.
Before you upgrade:
■
Verify that there is a connection between the TFTP server and the Switch 7700
(use the
ping
command.)
■
Verify that the TFTP server is set up according to the manufacturer's instructions
and that it is enabled and pointing to the correct directory.
To upgrade using TFTP:
1
Verify that you are logged in with super-user privileges.
2
From the Switch 7700 command line (in user view), TFTP the image file from the
TFTP server to the Switch 7700 using the following command:
tftp <TFTP Server IP Address> get <Source File/image>< Dest
File-Optional>
3
Set the boot parameters to specify the file to boot the system from, using the
following command:
boot boot-loader filename
4
Reboot the system.
The following example illustrates this procedure:
<SW7700>
tftp 10.10.110.1 get sw7700003.app
Transfer file in binary mode.
Now begin to download file from remote tftp server, please wait...
/
TFTP: 5690749 bytes received in 376 second(s).
File downloaded successfully.
<SW7700>
boot boot-loader sw7700003.app
The specified file will be booted next time!
<SW7700>
reboot
This command will reboot the system. Continue? [Y/N]
