l The BootWare program is automatically upgraded when applications are upgraded, that is, you
do not need to upgrade the BootWare program separately.
l The file name, size, and path in the above figures may vary. Check the current BootWare and
application versions before upgrading them.
l If you upgraded the extended segment, you only upgrade part of the BootWare program. Once
an error occurs, you can start the BootWare upgrade process again
Upgrading Applications Using TFTP
When application files are large, you can upgrade them using the Trivial File Transfer Protocol (TFTP)
to greatly shorten the upgrade and maintenance time.
TFTP, a protocol in the TCP/IP suite, is used for trivial file transfer between client and server to
provide simple, low-overhead file transfer services. TFTP provides unreliable data transfer services
over the User Datagram Protocol (UDP) and does not provide any access authorization or
authentication mechanism. It employs timeout and retransmission to guarantee data delivery.
The SecBlade card serves as the TFTP client while the file server serves as the TFTP server. You can
upload/download applications to/from the file server by entering a corresponding command on the
configuration terminal.
You can upgrade application files using TFTP in the following two ways:
l On the BootWare menu
l At the CLI
Upgrading Applications Using TFTP on the BootWare Menu
1) Set up a TFTP upgrade environment.
l The SecBlade card serves as the TFTP client while the PC serves as the TFTP server.
l Use a crossover Ethernet cable to connect Ethernet interface GigabitEthernet 0/2 on the
SecBlade card to the PC and ensure the connectivity between the SecBlade card and the PC.
l Enable the TFTP server on the PC and set the path where the application files are stored.
l The TFTP server program is not shipped with the SecBlade card and you need to purchase and
install it.
l When you upgrade application files using TFTP on the BootWare menu, use Ethernet interface
GigabitEthernet 0/2 on the SecBlade card.
