Chapter 5 Switch Software Loading
The traditional switch software loading is serial loading, but it is slow and time-consuming, and it cannot realize remote loading
and is inconvenient for operation. To address these problems, TFTP module is introduced to switch to facilitate software loading
and file download via Ethernet. Specific operations are as follows:
Enter uBoot operation mode
To enter uBoot operation mode, press the combined key Ctrl + b during the switch startup when press Ctrl + b to stop auto-
boot: is prompted; startup information is as follows:
Restarting system.
U-Boot 3.0.2 (Development build) (Build time: May 10 201-17:14:19)
P1010 board revision major: 1, minor: 0, serial #:
P1010 pass 1.1, Core clock: 533 MHz, DDR clock: 265 MHz (530 Mhz data rate)
Board descriptor tuple not found in eeprom, using defaults
DRAM: 1 GB
Clearing DRAM...... done
Flash: 2 GB
BIST check passed.
Net: octeth0, octeth1
Press Ctrl + b to stop autoboot: 3 – Press Ctrl + b to enter uBoot operation mode
Identify a PC as loading server, connect the administration port of switch and the PC with net line; set IP address of the PC and
administration IP address of the switch for the same network segment; specific operations are as follows:
• Use the command help open_all to open all commands.
• Use the command setenv ipaddr address to set the administration IP address of the switch; the switch will copy image files to
the switch from TFTP server using this address.
• Use the command setenv serverip address to set the IP address of TFTP server; the switch will copy image files from this
TFTP server.
• Use the command ping to check if the switch communicates with the loading server.
• Can use the command printenv to view the current environment variables of switch.
• Can use the command saveenv to save the current environment variables of switch to EPROM.
• Can use the command reenv to restore the environment variables of switch to default value.
Run TFTP Server program on PC as a server, and set the directory where loading files are located; uBoot file supposed to be
upgraded is u_boot_v1.0.bin.
Run the command upgrade_uboot u_boot_v1.0.bin to upgrade uBoot; here the filename is u_boot_v1.0.bin.
Run the command reset to complete the upgrade of uBoot.
