The page refreshes and displays the SNTP Global Configuration section and the SNTP
Global Status section.
The default is SNTP. The local clock can be set to SNTP only if the following two
conditions are met:
• The SNTP server is configured.
• The SNTP last attempt status is successful.
7. Next to Client Mode, select the mode of operation of the SNTP client:
• Disable. SNTP is not operational. No SNTP requests are sent from the client nor are
any incoming SNTP messages processed.
• Unicast. SNTP operates in a point-to-point fashion. A unicast client sends a request
to a designated server at its unicast address and expects a reply from which it can
determine the time and, optionally, the round-trip delay and local clock offset relative
to the server.
• Broadcast. SNTP operates in the same manner as multicast mode but uses a local
broadcast address instead of a multicast address. The broadcast address provides a
single-subnet scope while a multicast address provides an Internet-wide scope.
The default is Disable.
8. If the SNTP client mode is Unicast, you can add the IP address or DNS name of one or
more SNTP servers for the switch to poll.
For more information, see
9. In the Port field, specify the local UDP port that the SNTP client receives server packets on.
The allowed range is 1025 to 65535 and 123. The default is 123. When the default is
configured, the actual client port value used in SNTP packets is assigned by the OS.
10. In the Unicast Poll Interval field, specify the number of seconds between unicast poll
requests expressed as a power of 2. to The allowed range is 6 to 10. The default is 6.
11. In the Broadcast Poll Interval field, specify the number of seconds between broadcast poll
requests expressed as a power of 2.
Broadcasts received prior to the expiry of this interval are discarded. The allowed range is
6 to 10. The default is 6.
12. In the Unicast Poll Timeout field, specify the number of seconds to wait for an SNTP
response to a unicast poll request.
The allowed range is 1 to 30. The default is 5.
13. In the Unicast Poll Retry field, specify the number of times to retry a unicast poll request to
an SNTP server after the first time-out before the switch attempts to use the next configured
server.
The allowed range is 0 to 10. The default is 1.
14. In the Time Zone Name field, specify a time zone.
