Chapter 39 Configuring NTP
Configuring NTP on the Switch
This example shows how to configure the NTP server address, enable NTP client and authentication
modes on the switch, and verify the configuration:
Console> (enable) set ntp server 172.20.52.65 key 879
NTP server 172.20.52.65 with key 879 added.
Console> (enable) set ntp client enable
NTP Client mode enabled
Console> (enable) set ntp authentication enable
NTP authentication feature enabled
Console> (enable) show ntp

Setting the Time Zone
You can set a time zone for the switch to display the time in that time zone. You must enable NTP before
you set the time zone. If NTP is not enabled, this command has no effect. If you enable NTP and do not
specify a time zone, UTC is shown by default.
To set the time zone, perform this task in privileged mode:
This example shows how to set the time zone on the switch:
Console> (enable) set timezone Pacific -8
Timezone set to 'Pacific', offset from UTC is -8 hours
Console> (enable)
Enabling the Daylight Saving Time Adjustment
Following U.S. standards, you can have the switch advance the clock one hour at 2:00 a.m. on the first
Sunday in April and move the clock back one hour at 2:00 a.m. on the last Sunday in October. You can
also explicitly specify start and end dates and times and whether the time adjustment recurs every year.
