FIGURE 93 Wireless Controller - Captive Portal screen
The Captive Portal screen displays the following:
Network Time
Controller Statistics
Network Time Protocol (NTP) is central to networks that rely on their controller or service platform
to supply system time. Without NTP, system time is unpredictable, which can result in data loss,
failed processes and compromised security. With network speed, memory, and capability
increasing at an exponential rate, the accuracy, precision, and synchronization of network time is
essential in a controller or service platform managed network. The controller or service platform
can use a dedicated server to supply system time. The controller or service platform can also use
several forms of NTP messaging to sync system time with authenticated network traffic.
Client MAC Displays the requesting client’s MAC address. The MAC displays as a link that can be selected to display
client configuration and network address information in greater detail.
Client IP Displays the requesting client’s IP address.
Captive Portal Displays the captive portal page’s IP address.
Authentication Displays the authentication status of the requesting client.
WLAN Displays the name of the WLAN the client belongs to.
VLAN Displays the name of the requesting client’s VLAN interface.
Remaining Time Displays the time after which the client is disconnected from the captive portal managed Internet.
