Configuring Network Time

You should synchronize the clocks of the controller and the APs to ensure that the logs and reports reflect accurate time stamps. For more information, see Working with Reports and Statistics.

The normal operation of the controller will not be affected if you do not synchronize the clock. The clock synchronization is necessary to ensure that the logs display accurate time stamps. In addition, clock synchronization of network elements is a prerequisite for the following configuration:

• Mobility Manager
• Session Availability

Network time is synchronized in one of two ways:

• Using the system‘s time — The system‘s time is the controller‘s time.
• Using Network Time Protocol (NTP) — The Network Time Protocol is a protocol for synchronizing the clocks of computer systems over packet-switched data networks.

The controller automatically adjusts for any time change due to Daylight Savings time.
