How Do I Use Redirection Parameters?
You can run the url-parameter command to specify the parameters carried in a URL. The parameters to be carried need to be confirmed with the Portal server. For example, if a Portal server needs to carry the STA's MAC address and uses the keyword mac to identify the STA's MAC address, you can run the following command:
url-parameter user-mac mac
The keywords user-mac and mac are used by the Huawei device and Portal server respectively to identify the STA's MAC address.
