Figure 14 Disabling time synchronization by disabling the SNTP mode
Configuring the SNTP mode
Enabling the SNTP mode means to configure it for either broadcast or unicast mode. Remember
that to run SNTP as the switch's time synchronization protocol, you must also select SNTP as the
time synchronization method by using the CLI timesync command (or the menu interface Time
Sync Method parameter.)
Syntax
timesync sntp
Selects SNTP as the time protocol.
sntp <broadcast|unicast>
Enables the SNTP mode.
Syntax
sntp server <ip-addr>
Required only for unicast mode.
Syntax
sntp server priority <1-3>
Specifies the order in which the configured servers are polled for getting the time.
Value is between 1 and 3.
Syntax
sntp <30-720>
Configures the amount of time between updates of the system clock via SNTP.
Default: 720 seconds
Enabling SNTP in broadcast mode
Because the switch provides an SNTP polling interval (default:720 seconds), you need only these
two commands for minimal SNTP broadcast configuration:
Syntax
timesync sntp
Selects SNTP as the time synchronization method.
Syntax
sntp broadcast
Configures broadcast as the SNTP mode.
