Fig 12-1 Typical SNTP Configuration
All ES4626/ES4650 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 ES4626/ES4650 and the two SNTP/NTP servers. 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 ES4626/ES4650
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).
