I will give an example of updating the firmware of the Huawei Quidway S3928P-EI switch.
We look at the current firmware version:
display version
Let’s see what firmware files are in the device’s memory:
dir
If you do not have a firmware file, then you can download it from another similar switch, for example:
tftp 192.168.5.5 put ixnfo.com.bin
The command to download the firmware file to the switch’s memory:
tftp 192.168.5.5 get ixnfo.com.bin
Specify that the switch should be loaded from this file:
startup system-software ixnfo.com.bin
display startup
Restart the switch:
reboot
