62.2 Typical Examples of SNTP Configuration
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
SNTP/NTP
SERVER
SNTP/NTP
SERVER
