Configuring Network Time - Extreme Networks Summit WM User Manual

Configuring the Summit WM Controller
NOTE
If the RADIUS connectivity test displays "successful" result, you must click Save on the RADIUS Authentication
screen (as depicted in Step 4) to save your configuration. After you save your changes, you will be logged out of the
Summit WM Controller. You must use the RADIUS login user name and password to log on the Summit WM
Controller.

Configuring network time

You can synchronize the network elements to a universal clock. This ensures accuracy in usage logs.
Network time is synchronized in one of two ways:
Using system time
Using Network Time Protocol (NTP), an Internet standard protocol that synchronizes client
workstation clocks.
NOTE
If the Summit WM Controller is left powered-down for more than 78 hours, its capacitor dies down and is unable to
keep the system clock working. In such a case, you must synchronize the network time, using the NTP server. If the
NTP server is not reachable, you must first manually set the system to the correct time, and then use the system
time to synchronize the network time.
To apply time zone settings:
1 From the main menu, click Wireless Controller Configuration. The Wireless Controller
Configuration page is displayed.
2 In the left pane, click Network Time. The Network Time page is displayed.
