Huawei system upgrade and patch installation

This article simply describes how to perform a system upgrade for a Huawei device (switch, router, WLAN controller, etc.) and install a patch.

Upgrading a Huawei device can be done in different ways. This example describes the way via the CLI with uploading the image using SCP.

1.

Download the right system image and patch from the Huawei website. The respective model is entered in the search bar. If you don't know your exact model then you can find it out from the CLI using display version. The system images has the ending .cc and the patches .pat.

➡️ It is important to read the release notes to find out possible dependencies.
2.

Upload the image and patch to the Huawei device. This can be done for example with SCP - see the article File upload to Huawei device with SSH.
3.

Check with the command dir if the image (e.g. s5720li-v200r011c10spc600.cc) and patch (s5720li-v200r011sph005.pat) is saved in the flash.
4.

Check if the image is valid (command is only available on newer Huawei CloudEngine switches)

<HUAWEI> check system-software s5720li-v200r011c10spc600.cc
5.

Configure the switch to load the new system image the next time it reboots

<HUAWEI> startup system-software flash:/s5720li-v200r011c10spc600.cc
6.

Configure the switch to load the new patch the next time it reboots

<HUAWEI> startup patch flash:/s5720li-v200r011sph005.pat
