3 Configuring the Switch

CLI – This example configures the switch to operate as an SNTP unicast client and then displays the current time and settings.

Console(config)#sntp server 10.1.0.19 137.82.140.80 128.250.36.2

4-54

Console(config)#sntp poll 60

4-55

Console(config)#sntp client

4-53

Console(config)#exit

 

Console#show sntp

 

Current time:

Jan 6 14:56:05 2004

 

Poll interval: 60

 

Current mode:

unicast

 

SNTP status : Enabled

 

SNTP server 10.1.0.19 137.82.140.80 128.250.36.2

 

Current server: 128.250.36.2

Setting the Time Zone

SNTP uses Coordinated Universal Time (or UTC, formerly Greenwich Mean Time, or GMT) based on the time at the Earth’s prime meridian, zero degrees longitude. To display a time corresponding to your local time, you must indicate the number of hours and minutes your time zone is east (before) or west (after) of UTC.

Command Attributes

Current Time – Displays the current time.

Name – Assigns a name to the time zone. (Range: 1-29 characters)

Hours (0-12)– The number of hours before/after UTC.

Minutes (0-59)– The number of minutes before/after UTC.

Direction – Configures the time zone to be before (east) or after (west) UTC.

Web – Select SNTP, Clock Time Zone. Set the offset for your time zone relative to the UTC, and click Apply.
