If
include-credentials
is configured, the SNTP authentication configuration is saved in the configuration file.
When the
show config
command is entered, all of the information that has been configured for SNTP
authentication displays, including the key-values.

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.
If there are already three SNTP server addresses configured on the switch, and you want to use the CLI to
replace one of the existing addresses with a new one, you must delete the unwanted address before you
configure the new one.
Displaying all SNTP server addresses configured on the switch (CLI)
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.
How to list all SNTP servers configured on the switch
switch(config)# show management
