System Management Commands 4

ntp client

This command enables NTP client requests for time synchronization from NTP time servers specified with the ntp servers command. Use the no form to disable NTP client requests.

Syntax

[no] ntp client

Default Setting

Disabled

Command Mode

Global Configuration

Command Usage

•The SNTP and NTP clients cannot be enabled at the same time. First disable the SNTP client before using this command.

•The time acquired from time servers is used to record accurate dates and times for log events. Without NTP, the switch only records the time starting from the factory default set at the last bootup (i.e., 00:00:00, Jan. 1, 2001).

•This command enables client time requests to time servers specified via the ntp servers command. It issues time synchronization requests based on the interval set via the ntp poll command.

Example

Console(config)#ntp client

Console(config)#

Related Commands

sntp client (4-54) ntp poll (4-58) ntp server (4-57)

ntp server

This command sets the IP addresses of the servers to which NTP time requests are issued. Use the no form of the command to clear a specific time server or all servers from the current list.

Syntax

ntp server ip-address [version number] [key key-number]no ntp server [ip-address]

•ip-address- IP address of an NTP time server.

•number - The NTP version number supported by the server. (Range: 1-3)

•key-number- The number of an authentication key to use in communications with the server. (Range: 1-65535)

4-57
