12.3 Typical SNTP Configuration Examples
Fig 12-2 Typical SNTP Configuration
All ES4700 series 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 ES4700 series 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 ES4700 series should like the following:
Switch#config
Switch (Config)#sntp server 10.1.1.1
Switch (Config)#sntp server 20.1.1.1
From now on, SNTP would perform time synchronization to the server according to the
default setting (polltime 64s, version 1).
