Fig 15-2 Typical SNTP Configuration
All ES4710BD 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 ES4710BD 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
ES4710BD 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).
