The following table describes the nonconfigurable information displayed on the screen.
Captive Portal
The captive portal feature allows you to prevent clients from accessing the network until user 
verification is established. You can configure captive portal verification to allow access for 
both guest and authenticated users. Authenticated users must be validated against a 
database of authorized captive portal users before access is granted. The database can be 
stored locally on the device or on a RADIUS server. 
Configure Captive Portal Global Settings
You can control the administrative state of the captive portal feature, and configure global 
settings that affect all captive portals configured on the switch.
