NETGEAR 8800 User Manual

Automatic Daylight Saving Time changes can be enabled or disabled. The default setting

is enabled. To disable automatic Daylight Saving Time, use the command:

configure timezone {name <tz_name>} <GMT_offset> noautodst

3. Enable the SNTP client using the following command:

enable sntp-client

After SNTP has been enabled, the switch sends out a periodic query to the NTP servers

defined in

step 4 (if configured) or listens to broadcast NTP updates from the network.

The network time information is automatically saved into the onboard real-time clock.

4. If you would like this switch to use a directed query to the NTP server, configure the switch

to use the NTP server(s). An NTP server can be an IPv4 address or an IPv6 address or a

hostname. If the switch listens to NTP broadcasts, skip this step. To configure the switch to

use a directed query, use the following command:

configure sntp-client [primary | secondary] <host-name-or-ip> {vr <vr_name>}

The following two examples use an IPv6 address as an NTP server and a hostname as

an NTP server:

dst_timezone_ID Specifies an optional name for this Daylight Saving Time specification. May be up to six

characters in length. The default is an empty string.
