3.

Reset the system clock manually if the time, time zone, or summer time settings are
incorrect.

4.

If you want to configure the NTP system as an NTP client, choose the NTP servers.

Choosing NTP Servers

For the system, synchronizing to several stratum 2 or higher servers on the Internet
provides sufficient accuracy for the timing of event messages. You can find a list of
stratum 2 servers at

www.eecis.udel.edu/~mills/ntp.

If you have access to an NTP server that you know to be reliable and accurate, you can
synchronize the system to that server alone. You may prefer this method if you have used
Simple Network Time Protocol (SNTP) with other equipment.

If you know that an NTP server broadcasts on a network to which the system has an
interface, you do not need to configure NTP servers. Simply enable the system to accept
NTP broadcasts on that interface.

NTP Configuration Tasks

By default, the system is an NTP client. You must configure NTP client parameters to
start NTP client operation. You can also configure the system as an NTP server, whether
or not you configure NTP client parameters.

Enabling NTP Services

Before you can configure NTP client parameters or enable a virtual router to act as an
NTP server, you must enable NTP services. When you enable NTP services, the NTP client
associates itself with the current virtual router. Because there is only one system clock
to update, only the virtual router on which you configure NTP can act as the NTP client.
However, any virtual router can act as an NTP server. To enable NTP services:

1.

(Optional) Access the virtual router with which you want to associate NTP services.

2.

Issue the

ntp enable

command.

ntp enable

•

Use to enable NTP services on the system.

•

This command associates NTP services and the NTP client with the current virtual
router.

•

Example

host1:boston(config)#

ntp enable

•

Use the

no

version to disable NTP polling and clock correction and to remove the

association between NTP services and the virtual router.

•

See ntp enable.
