Traditionally, the loading of switch
software is accomplished through a serial port. This approach is slow,
inconvenient, and cannot be used for remote loading. To resolve these problems,
the TFTP and FTP modules are introduced into the switch. With these modules,
you can load/download software/files conveniently to the switch through an Ethernet
port.
This chapter introduces how to load BootROM
and host software to a switch locally and how to do this remotely.
You can load software locally by using:
l
XMODEM through Console port
l
TFTP through Ethernet port
l
FTP through Ethernet port
You can load software remotely by using:
l
FTP
l
TFTP
The BootROM
software version should be compatible with the host software version when you
load the BootROM and host software.
If your terminal is directly connected to
the switch, you can load the BootROM and host software locally.
Before loading the software, make sure that
your terminal is correctly connected to the switch to insure successful loading.
The loading process of the BootROM software is the same as that of
the host software, except that during the former process, you should press <Ctrl+U>
and <Enter> after entering the Boot Menu and the system gives different
prompts. The following text mainly describes the BootROM loading process.

I. Introduction to XMODEM
XMODEM is a file transfer protocol that is widely
used due to its simplicity and good performance. XMODEM transfers files via
Console port. It supports two types of data packets (128 bytes and 1 KB), two
check methods (checksum and CRC), and multiple attempts of error packet
retransmission (generally the maximum number of retransmission attempts is ten).
The XMODEM transmission procedure is
completed by a receiving program and a sending program: The receiving program sends
negotiation characters to negotiate a packet checking method. After the
negotiation, the sending program starts to transmit data packets. When
receiving a complete packet, the receiving program checks the packet using the
agreed method. If the check succeeds, the receiving program sends an
acknowledgement character and the sending program proceeds to send another
packet; otherwise, the receiving program sends a negative acknowledgement
character and the sending program retransmits the packet.
II. Loading BootROM software
Follow these steps to load the BootROM software:
Step 1: At the prompt "Enter your
choice(0-9):" in the Boot Menu, press <6> or <Ctrl+U>, and then
press <Enter> to enter the BootROM update menu shown below:

the switch.
Step 2: Update the BootROM program on the
switch.
<H3C> boot bootrom S3100-52P.btm
This will update BootRom file on
unit 1. Continue? [Y/N] y
Upgrading BOOTROM, please wait...
Upgrade BOOTROM succeeded!
Step 3: Restart the switch.
<H3C> reboot
Before restarting
the switch, make sure you have saved all other configurations that you want, so
as to avoid losing configuration information.
2)
Loading host software
Loading the host software is the same as
loading the BootROM program, except for that the file to be downloaded is the
host software file, and that you need to use the boot boot-loader
command to select the host software at reboot of the switch.
After the above operations, the BootROM and
host software loading is completed.
Pay attention to the following:
l
The loading of BootROM and host software takes
effect only after you restart the switch with the reboot command.
l
If the space of the Flash memory is not enough,
you can delete the useless files in the Flash memory before software downloading.
l
No power-down is permitted during software
loading.
II. Loading Process Using FTP
Server
As shown in Figure 1-9, the switch is used as the FTP server. You can telnet to the
switch, and then execute the FTP commands to download the BootROM program S3100-52P.btm
from the switch.
1)
Loading BootROM
Figure 1-9 Remote loading using FTP
server
Step 1: As shown in Figure 1-9, connect the switch through an Ethernet port to the PC (with IP
address 10.1.1.1)
Step 2: Configure the IP address of VLAN1
on the switch to 192.168.0.39, and subnet mask to 255.255.255.0.
You can configure
the IP address for any VLAN on the switch for FTP transmission. However, before
configuring the IP address for a VLAN interface, you have to make sure whether
the IP addresses of this VLAN and PC are routable.
<H3C> system-view
System View: return to User View with
Ctrl+Z.
[H3C] interface Vlan-interface 1
[H3C-Vlan-interface1] ip address
192.168.0.39 255.255.255.0
Step 3: Enable FTP service on the switch,
configure the FTP user name to test and password to pass.
[H3C-Vlan-interface1] quit
[H3C] ftp server enable
[H3C] local-user test
New local user added.
[H3C-luser-test] password simple pass
[H3C-luser-test] service-type ftp
Step 4: Enable FTP client software on PC. Refer
to Figure 1-10 for the command line interface in Windows operating system.
Figure 1-10 Command line interface
Step 5: Enter cd in the interface to switch
to the path that the BootROM upgrade file is to be stored, and assume the name
of the path is “D:\Bootrom”, as shown in Figure 1-11.
Figure 1-11 Switch to BootROM
Step 6: Enter “ftp 192.168.0.39”
and enter the user name test, password pass, as shown in Figure 1-12, to log on the FTP server.
Figure 1-12 Log on the FTP server
Step 7: Use the put command to
upload the file S3100-52P.btm to the switch, as shown in Figure 1-13.
Figure 1-13 Upload file S3100-52P.btm to
the switch
Step 8: Configure S3100-52P.btm to be the BootROM
at reboot, and then restart the switch.
<H3C> boot bootrom S3100-52P.btm
This will update Bootrom on unit 1.
Continue? [Y/N] y
Upgrading Bootrom, please wait...
Upgrade Bootrom succeeded!
<H3C> reboot
When rebooting the switch, use the file S3100-52P.btm
as BootROM to finish BootROM loading.
2)
Loading host software
Loading the host software is the same as
loading the BootROM program, except for that the file to be downloaded is the
host software file, and that you need to use the boot boot-loader
command to select the host software at reboot of the switch.
l
The steps listed above are performed in the
Windows operating system, if you use other FTP client software, refer to the
corresponding user’s guide before operation.
l
Only the configurations steps concerning loading
are illustrated here, for detailed description on the corresponding
configuration commands, refer to the chapter “FTP and TFTP”.
The remote loading using TFTP is similar to
that using FTP. The only difference is that TFTP is used instead off FTP to load
software to the switch, and the switch can only act as a TFTP client.
