Set The Time Manually - NETGEAR S3600 Series User Manual

S3600 Series 8- or 16-Port 10G/Multi-Gigabit Ethernet Smart Switch with 2 SFP+ Ports
• The toggle is gray and positioned to the left: An NTP packet from an NTP
server is not authenticated.
• The toggle is purple and positioned to the right: An NTP packet from an NTP
server is authenticated. The authentication is based on SHA256. If the packet
cannot be authenticated, it is dropped, and the switch cannot synchronize its
time with the NTP server that sent the packet. By default, this mode is enabled.
10. Click the NTP Broadcast Client Mode toggle to enable or disable the switch from
broadcasting NTP requests to an NTP server:
• The toggle is gray and positioned to the left: The switch does not broadcasts
NTP requests to an NTP server.
• The toggle is purple and positioned to the right: The switch broadcasts NTP
requests to an NTP server. By default, this mode is enabled.
NOTE: Broadcasting an NTP request can still be useful if there is no public
NTP server configured on the switch because it allows the switch to
synchronize its time with an NTP server that is accessible in the network,
as opposed to an external time server, such a public time server.
11. In the Broadcast Delay field, specify the estimated round-trip delay in microseconds
between the NTP client and the NTP broadcast server.
The range is from 1 to 999999. The default is 3000.
The delay is the period that is lost between the outgoing request and the incoming
response because of network traffic and routing. The switch adds the delay that you
specify to the time that it receives from the NTP server so that the switch can calculate
the actual time.
12. From the Source Interface menu, select the outbound interface.
The NTP client uses the source IP address of this interface to broadcast NTP queries.
By default, no source interface is configured.
13. Click the Apply button.
Your settings are saved.
