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.
