Hi,
The default format of the MAC address in the calling-station-id attribute of RADIUS packets from the device is xxxx-xxxx-xxxx, which means you can get the value by checking the device's MAC address.
Since the AC device supports configuring the ip address under the logical interface, you can get the device's MAC by executing the command 'display interface vlanif 1'. Kindly refer to the example below:
<Huawei>display interface vlanif 1
Vlanif1 current state : UP
Line protocol current state : DOWN
