NOTE:
•
The BootWare program is automatically upgraded when applications are upgraded, that is, you do not
need to upgrade the BootWare program separately.
•
The file name, size, and path in the above figures may vary. Check the current BootWare and
application versions before upgrading them.
•
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 with 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:
•
On the BootWare menu
•
At the CLI
Upgrading Applications with TFTP on the BootWare Menu
1.
Set up a TFTP upgrade environment.
•
The SecBlade card serves as the TFTP client while the PC serves as the TFTP server.
•
Use a crossover Ethernet cable to connect default management Ethernet interface GigabitEthernet
0/1 on the SecBlade card to the PC and ensure the connectivity between the SecBlade card and
the PC. Different cards have different default management Ethernet ports. For specific information,
and
.
•
Enable the TFTP server on the PC and set the path where the application files are stored.
NOTE:
•
The TFTP server program is not shipped with the SecBlade card and you need to purchase and install it.
•
When you upgrade application files using TFTP on the IPS LSWM1IPS10 card, you need to connect the
management Ethernet interface meth 0/0 of the card to the PC.
•
For the SSL VPN card, because the card does not provide service ports on its panel, you need to use a
crossover Ethernet cable to connect the service port (such as GigabitEthernet 3/0/1) of the switch or
router to the PC, and guarantee that the SecBlade SSL VPN card can communicate with the PC.
2.
Configure Ethernet interface parameters on the BootWare menu.
Select 3 on the main menu to enter the Ethernet submenu, where you can select 5 to enter the Ethernet
parameter setting interface to configure the Ethernet interface parameters.
