9800-CL WLC 17.3.1 - External Webauth - Append Parameters

[yprasannas]

Hello, Any one using External Webauth with append parameters? 

In the AIROS if external webauth (Web Authentication on WLAN Controller - Cisco) is used for SSID, the request to external URL is redirected by appending parameters - AP MAC address, Client MAC address, SSID and initial redirect url. It would look like ..https://IPAddress_external_server/somepage.html?switch_url=http://virtualIP/login.html&ap_mac=20:00:00:00:00:23&client_mac=11:22:22:44:55:66&wlan=testssid&redirect=msn.com/

In the  9800 Series - code 17.3.1 , by default the append parameters is not happening. Guide mentions to hardcode values. Is there a way to dynamically generate these values?

Any inputs is appreciated. 

Thank you!
