Switch management features 69

The SNTP supports primary and secondary NTP servers. The system tries

the secondary NTP server only if the primary NTP server is unresponsive.

Conﬁguring with CLI

To use the CLI to conﬁgure the SNTP feature, use the following procedure:

Step Action

Set the primary and secondary NTP server.

Enable the SNTP.

Display the UTC time.

Optionally, to ensure the synchronization happens immediately,

force a synchronization.

—End—

Setting local time zone

The SNTP uses Universal Coordinated Time (UTC) for all time

synchronizations so it is not affected by different time zones. For the switch

to report the correct time for your local time zone and daylight savings time,

you must use the following commands:

•

"clock time-zone" (page 213)

•

"no clock time-zone" (page 213)

• "clock summer-time" (page 213)

•

"no clock summer-time" (page 214)

•

"show clock time-zone" (page 214)

• Figure 75 "show clock summer-time" (page 215)

Using DNS to ping and Telnet

You can use the DNS client to ping or Telnet to a host server or to a host

by name.

To use this feature, you must conﬁgure at least one Domain Name Server

(DNS). You can also conﬁgure a default domain name. If you conﬁgure

a default domain name, that name is appended to host names that do

not contain a dot. The default domain name and addresses are saved in

NVRAM.
