Command Usage
• This command specifies time servers that the switch will poll for time updates when
set to NTP client mode. It issues time synchronization requests based on the
interval set with the ntp poll command. The client will poll all the time servers
configured, the responses received are filtered and compared to determine the
most reliable and accurate time update for the switch.
• You can configure up to 50 NTP servers on the switch. Re-enter this command for
each server you want to configure.
• NTP authentication is optional. If enabled with the ntp authenticate command, you
must also configure at least one key number using the ntp authentication-key
command.
•Use the no form of this command without an argument to clear all configured
servers in the list.
