Time Protocols SNTP Unicast Time Polling with Multiple SNTP Servers SNTP Unicast Time Polling with Multiple SNTP Servers When running SNTP unicast time polling as the time synchronization method, the switch requests a time update from the server you configured with either the Server Address parameter in the menu interface, or the primary server in a list of up to three SNTP servers configured using the CLI. If the switch does not receive a response from the primary server after three consecutive polling intervals, the switch tries the next server (if any) in the list. If the switch tries all servers in the list without success, it sends an error message to the Event Log and reschedules to try the address list again after the configured Poll Interval time has expired. Displaying All SNTP Server Addresses Configured on the Switch The System Information screen in the menu interface displays only one SNTP server address, even if the switch is configured for two or three servers. The CLI show management command displays all configured SNTP servers on the switch.
