Figure 62-2:

Typical SNTP Configuration

All switches in the autonomous zone are required to perform time synchronization, which is done through two

redundant SNTP/NTP servers. For time to be synchronized, the network must be properly configured. There

should be reachable route between any switch and the two SNTP/NTP servers.

For example, assume the IP addresses of the SNTP/NTP servers are 10.1.1.1 and 20.1.1.1, respectively,

and SNTP/NTP server function (such as NTP master) is enabled, then configurations for any switch should

like the following:

Switch#config

Switch(config)#sntp server 10.1.1.1
