Setting SNTP
A switch can be configured to synchronize its system clock with an SNTP server
by using the
SNTP Settings Page
.
NOTE This feature requires that the DNS servers be configured on the switch (see the
Defining DNS Servers section) to work properly.
The switch supports the following modes:
• Broadcast—The SNTP server broadcasts the time, and the switch listens to
these broadcasts. When the switch is in this mode, there is no need to
define a Unicast SNTP server.
• Unicast SNTP Server Mode—The switch sends Unicast queries to the list of
manually-configured SNTP servers, and waits for a response.
The switch supports having both modes active at the same time, choosing the
best source of the parameters according to the closest stratum (distance from the
reference clock.).
To define SNTP server settings:
STEP 1 Click Administration > Time Settings > SNTP Settings. The
SNTP Settings Page
opens.
STEP 2 (Optional) Select SNTP Broadcast Reception > Enable to listen to SNTP
Broadcast synchronization packets for system time information. If this option is
selected, the system does not display the SNTP server from which the time
parameters are received.
This page displays the following information for each Unicast SNTP server:
• SNTP Server—SNTP server IP address. Up to eight SNTP servers can be
defined. The preferred server is chosen according to its stratum level.
• Poll Interval—Interval (in seconds) at which the SNTP server is polled for
system time information. The poll interval is 1024 seconds.
