Configuring portal Web server detection

A portal authentication process cannot complete if the communication between the access device and the portal Web server is broken. To address this problem, you can enable portal Web server detection on the access device.

With the portal Web server detection feature, the access device simulates a Web access process to initiate a TCP connection to the portal Web server. If the TCP connection can be established successfully, the access device considers the detection successful, and the portal Web server is reachable. Otherwise, it considers the detection to have failed. Portal authentication status on interfaces of the access device does not affect the portal Web server detection feature.

You can configure the following detection parameters:
