39.2 Typical Examples of SNTP Configuration
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.
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
switch
