Troubleshooting :


completed different combination of configuration but no help


1) poe force-power

2)  poe legacy enable

poe high-inrush enable [ slot slot-id ]

3) port priority high

Althoug Same setup with different switch : controller is able to show appropiate power

Working fine in defaullt mode itself : Access controller is showing good power

Hi, yogijain,
I am afraid that your problem can only be handled by R&D. You are advised to contact TAC again, tell them about Cisco's conclusion, and then open another ticket.

Hi,
As we talked in the thread you posted before, I think it is the inconsistent negotiation of power supply caused the problem.
But you indicated the Cisco denies any issues at their terminal, maybe you can contact with the Huawei TAC to ask them for the information of the Cisco IP phone needed during the troublshooting, then seek Cisco engineers for providing the corresponding data.

One way to get around this problem is to add power injectors as you said in previous thread, this issue doesn't occur with S5720. So, it looks like a issue with power supplied to the AP.
