what should I take caution to when replace the cisco switch with a huawei s5720?

Most importantly, please check which STP protocol is used on a Cisco switch.

By default, Cisco switches run PVST+, while Huawei switches run MSTP - these two protocols are imcompatible (actually, they can work in compatibility in a specific enviroment), so you should reconfigure the Cisco switch to run the MSTP.

Alternatively, you can reconfigure the Huawei switch to run the VBST, which is compatible with PVST+.

Glad to help you! Any further questions, let us know.

Hi there, mate!
As @chenhui described VBST - Please, also take into account the quantity of VLANs that can be used with VBST. Huawei switches can provide the limited amount of VBST instances - it actually depends on the switch platform. So - if you are run out of 128 VBST instances (VLANS) - you should consider the Q-in-Q or Vlan translation model for cooperation/replacing other vendors switches.

Take care!

@ViktorG hi bro,
thanks for your guys, I'll check the documentation first.

And last but not the least to make sure STP priority is reduced on new switch than core switch, usually in good design they define less priority in CORE same as vlan ID :). Better put "root guard" on core switch downstream port.

Thank you.

Kindest regards,
