Table 1: SNTP parameters
SNTP parameter Operation
Time Sync Method Used to select either SNTP, TIMEP, NTP, or None as the time synchronization method.
SNTP Mode
Disabled
The Default. SNTP does not operate, even if specified by the Menu interface Time Sync
Method parameter or the CLI timesync command.
Unicast
Directs the switch to poll a specific server for SNTP time synchronization. Requires at
least one server address.
Broadcast
Directs the switch to acquire its time synchronization from data broadcast by any SNTP
server to the network broadcast address. The switch uses the first server detected and
ignores any others. However, if the Poll Interval expires three times without the switch
detecting a time update from the original server, the switch accepts a broadcast time
update from the next server it detects.
Poll Interval
(seconds)
In Unicast Mode: Specifies how often the switch polls the designated SNTP server for a
time update.In Broadcast Mode: Specifies how often the switch polls the network
broadcast address for a time update.Value is between 30 to 720 seconds.
Server Address Used only when the SNTP Mode is set to Unicast. Specifies the IP address of the SNTP
server that the switch accesses for time synchronization updates. You can configure up to
three servers; one using the menu or CLI, and two more using the CLI.
Server Version Specifies the SNTP software version to use and is assigned on a per-server basis. The
version setting is backwards-compatible. For example, using version 3 means that the
switch accepts versions 1 through 3. Default: 3; range: 1 to 7.
Priority Specifies the order in which the configured servers are polled for getting the time. Value is
between 1 and 3.
