1.6.7 Configuring SNTP
This section describes configuration information, procedures, and commands for SNTP.
1.6.7.1 Default Configuration
When an SBx3112 switch is initially booted up, the system time will be configured as follows:
• Standard Eastern Time, DST is OFF, and UTC offset is -5:00.
1.6.7.2 Configuration Guidelines
•
All command interactions are supported by both CLI and SNMP.
• DST support can be enabled or disabled, with the default setting disabled.
• Only a single time-zone can in effect at a time whether that is the user time-zone rule or one of the pre-
defined North-American time-zones.
• A Management Log entry is generated whenever DST starts or stops.
• Modifying the current system time will cause a reevaluation of whether or not DST is in effect.
• Disabling DST while DST settings are in effect will cause a reversion to the standard time UTC offset.
• If a pre-defined time-zone is being used, modifying the current UTC offset will generate a warning and clear
all of the DST settings.
• All logs (error, crash, trace, management) will indicate whether in DST or standard time. And all logs that
were generated prior to the onset of DST will retain their original time.
• The SHOW SYSTEM TIME command will indicate whether in DST or standard time.
1.6.7.3 Configuration Procedure
A typical SNTP configuration procedure involves the following steps:
• ADD SNTP SERVER - Inputs the hostname or IP address of the SNTP server that the Allied Telesis product will use.
• ENABLE SNTP - Activates the SNTP so that the SBx3112 will be able to synchronize its clock with the SNTP clock.
• SET SYSTEM TIMEZONE - Sets the timezone offset.
• RESET SNTP - Once the SNTP server is configured, this has the SBx3112 send an SNTP query to re-synchro-
nize the SBx3112 with the SNTP server. Note that the SNTP server must be enabled to do this.
To delete the SNTP server, the following sequence would be used:
• DISABLE SNTP - Deactivates the SNTP so that the SBx3112 will no longer synchronize its clock with the SNTP clock.
• DELETE SNTP SERVER - Deletes the hostname or IP address of the SNTP server that the SBx3112 is using.
