6 System Time Synchronized system clocks provide a frame of reference between all devices on the network. Network time synchronization is critical because every aspect of managing, securing, planning, and debugging a network involves determining when events occur. Without synchronized clocks, accurately correlating log files between devices when tracking security breaches or network usage is impossible. Synchronized time also reduces confusion in shared file systems, as it is important for the modification times to be consistent, regardless of the machine on which the file systems reside. For these reasons, it is important that the time configured on all of the devices on the network is accurate. NOTE The switch supports Simple Network Time Protocol (SNTP) and when enabled, the switch dynamically synchronizes the switch time with time from an SNTP server. The switch operates only as an SNTP client, and cannot provide time services to other devices. This section describes the options for configuring the system time, time zone, and Daylight Savings Time (DST). It covers the following topics: • System Time Options • SNTP Modes • Configuring System Time Cisco Small Business 200 Series Smart Switch Administration Guide 52
