Administration: Time Settings

Cisco 220 Series Smart Plus Switches Administration Guide Release 1.0.0.x
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.
The switch supports Simple Network Time Protocol (SNTP) and when enabled,
the switch dynamically synchronizes its time with the SNTP server time. The
switch operates only as an SNTP client and cannot provide time services to other
devices.
This chapter describes how to configure the system time, time zone, and Daylight
Savings Time (DST).
It includes the following topics:
• System Time Options
• Configuring System Time
• Configuring SNTP Server
