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-keycommand.

Use the no form of this command without an argument to clear all configured servers in the list.

Example

Console(config)#ntp server 192.168.3.20

Console(config)#ntp server 192.168.3.21

Console(config)#ntp server 192.168.4.22 version 2

Console(config)#ntp server 192.168.5.23 version 3 key 19
