Time Protocols
SNTP: Viewing, Selecting, and Configuring
To set the SNTP mode or change from one mode to the other, enter the
appropriate command.
Syntax
: sntp unicast
sntp broadcast
Enables SNTP for either broadcast or unicast mode.
Default: SNTP mode is disabled by default. SNTP does not
operate even if specified by the CLI
timesync
command or by
the menu interface
Time Sync Method
parameter.
Unicast:
Directs the switch to poll a specific server periodically
for SNTP time synchronization. The default value between each
polling request is 720 seconds but can be configured. At least
one manually configured server IP address is required.
Note:
At least one
key-id
must be configured as
trusted
and it
must be associated with one of the SNTP servers. To edit or
remove the associated
key-id
information or SNTP server
information, SNTP authentication must be disabled.
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
(configurable up to 720 seconds) 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.
Displaying SNTP Configuration Information
The
show sntp
command displays SNTP configuration information, including
any SNTP authentication keys that have been configured on the switch.
