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, it 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 between 30-720 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. Refer to “SNTP Unicast Time Polling with Multiple
SNTP Servers” on page 9-37.
Server Version
Default: 3; range: 1 - 7. 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.
Priority
Specifies the order in which the configured servers are polled for getting the time. Value is between
1 and 3.
