The Captive Portal screen displays the following:
Network Time
Access Point Statistics
Network Time Protocol (NTP) is central to networks that rely on their Access Point(s) to supply
system time. Without NTP, Access Point supplied network 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 an Access Point managed enterprise network. The Access Point can
use a dedicated server to supply system time. The Access Point can also use several forms of NTP
messaging to sync system time with authenticated network traffic.
The Network Time screen provides detailed statistics of an associated NTP Server of an Access
Point. Use this screen to review the statistics for each Access Point.
The Network Time statistics screen consists of two tabs:
• NTP Status
Client MAC Displays the MAC address of requesting wireless clients. The client address displays as a link that can
be selected to display configuration and network address information in greater detail.
Client IP Displays the IP addresses of captive portal resource requesting wireless clients.
Captive Portal Displays the IP address of the captive portal page.
Authentication Displays the authentication status of requesting clients.
WLAN Displays the name of the WLAN utilizing the Access Point managed captive portal.
VLAN Displays the name of the Access Point VLAN the requesting client uses a virtual interface for captive
portal sessions.
Remaining Time Displays the time after which the client is disconnected from the captive portal hosted Internet, and
Access Point connectivity.
