Chapter 1. X Family Startup Configuration

8 X Family CLI Reference V 2.5.1

Time Zone

The time zone option calculates and shows the local time. System logs are kept in Universal Time

(UTC), but the device calculates local time for display purposes. Entering the proper time zone enables

the device to display local time properly.

Daylight Saving Time

The daylight saving time option enables and disables the calculation of time based on the time of year.

NTP

The X family device can keep time using its internal CMOS clock or it can use a Network Time Protocol

(NTP) server.

NTP Server

Configuring a host as an NTP server causes the X family device to query that host to obtain

information on the current time. If multiple time servers are specified, the device aggregates data from

all available servers to calaculate the best time estimate. Providing multiple sources improves both the

reliability and accuracy of the time data.

NTP Peer

Configuring a host as an NTP peer causes the X family device to both send time information to and

receive time information from the host. This allows multiple devices to mutually exchange time

information, allowing for a higher resilience against the failure of one or more time servers.

Date and Time

If you are not using NTP, you must specify the current date and time.

Example

In this example, the time zone is set to Central Standard Time (CST), Daylight Saving Time changes are

enabled, and NTP is not enabled. The default date is accepted, and the current time is entered

manually:

Timekeeping options allow you to set the time zone, enable or

disable daylight saving time, and configure or disable NTP.

Would you like to modify timekeeping options? <Y,[N]>: y

Enter time zone or '?' for complete list [GMT]: CST

Automatically adjust clock for daylight saving changes? [Yes]: N

Do you want to enable the NTP client? [No]: N

Enter date <YYYY-MM-DD> [2006-06-09]:

Enter time <HH:MM:SS> in 24 hour notation [09:02:40]: 08:02:00

TimeZone: CST

DST enabled: No

NTP enabled: No

Date: 2006-06-09

Time: 08:02:00

Note: Use the show ntp session and sshow stp status commands to inspect

the operation of the NTP protocol.
