Hi alfred_loo,
You can use eNSP to simulate Huawei switches and routers for experiments.
Currently, the standalone eNSP has reached EOS and will not be downloaded or supported. The cloud-based eNSP is expected to be launched in the second half of the year. The old version can be used, you are kindly advised to contact your local channel/Huawei engineers to get eNSP.

Glad to help you! Any further questions, let us know.
By the way, you can get the eNSP at Download the eNSP - Huawei Enterprise Support Community, this is shared from our forum user.
